8Round.
Leg by leg.

At the top choose Train and, below, what you want to do:

• Level 1 to Level 4: the whole race —eight runs and eight stations, in order— with shorter distances and lighter weights, to build up to Open.
• Stations: a single exercise. Pick it by swiping the photos and set the metres, reps, kilos or resistance by moving the rulers.
• Free: the whole race with your own numbers, leg by leg. Under each ruler you see what Open and Pro ask for.

To start, tap the same button again: once chosen it turns orange and «Start» appears underneath, pulsing. If that mode is Plus and you don't have it, it says «Plus only» and shows you what's included.

It's the race's short fitness test, and in 8Round it's free. It's in 8Round › Train, the «PFT» button: tap it and, when «Start» appears underneath, tap it again.

• Six legs back to back, no rest: 1 km run, 50 burpee broad jumps, 100 bodyweight stationary lunges, 1 km row, 30 hand-release push-ups and 100 wall balls (6 kg men, 4 kg women).
• You do it with the usual timer: «Start» and «Done» on each leg.
• At the end, besides the summary, it tells you which level to compete in from your time: under 25 minutes, Pro; 25 to 35, Open; 30 to 40, Doubles; 35 to 45, Relay. The bands overlap on purpose, as the race publishes them.
• It's saved in your history as PFT and only compared with other PFTs; it doesn't enter the ranking.

Repeat it every few weeks to see how you improve.

One big button: «Start» begins each leg and «Done» ends it. The gap between them is your transition and it's timed separately, because that's where the minutes go.

• Top left, which leg you're on (for example, 2/16).
• Top right, the clock for the whole race and your best up to that point.
• At the bottom, the leg clock and your best for it. Orange while you're in it; white while you get ready.
• If you race a ghost (the white button between Open and Pro), under the top clock it says whether you're ahead (green) or behind (red).
• Without a ghost too: in the same place you see how far ahead or behind you are of your best identical race; if you don't have one yet, of your predicted time. It shows on the watch too.
• Tapped by mistake? For eight seconds «Undo» appears above the button: everything goes back as it was and the clock loses nothing.
• When training (not in Compete or the PFT) you can «Pause»: the clock stops until you tap «Resume». That race is saved marked and isn't compared with the ones you do without stopping.

Without pausing, the clock never stops: if you leave the app or it closes, when you come back it carries on with the real time. The heart rate strap is paired in Settings › Your account.

• Got a Garmin? No strap needed: on the watch, turn on «Broadcast Heart Rate» (in the controls menu) and find it in Settings › Your account › Heart rate strap, just like a strap. It works the same for other watches that broadcast heart rate over Bluetooth.

iPhone only. Every race you finish, complete or not, is saved automatically in the Health app as a «Mixed Cardio» workout with the 8Round icon. It also shows in the Fitness app.

• The first time you finish a race, the iPhone asks for permission: tap «Turn On All» and «Allow»; it also covers the Apple Watch heart rate and it won't ask again. If you say no, change it later in Health › your photo › Apps › 8Round.
• Each leg goes in as a segment, with its start and end time. The metres you run go in as distance.
• With a heart rate strap, the calories too, which count towards your Move ring, and your heart rate for the whole race, shown in the workout just as if the watch had measured it.
• With an Apple Watch there are no duplicates: the watch only measures your pulse and the iPhone saves the workout.
• Turn it off in Settings › General › Save to Apple Health.
• Strava: in Settings, «Upload to Strava» › «Connect» and give permission in Strava. From then on, every race you finish is uploaded to your Strava as a workout, with a lap for every run and station, your heart rate if you wore a sensor and the splits in the description. «Disconnect» removes it. You need an 8Round account.

In the summary of any workout tap «Share my workout». The first one is the usual card, the size of an Instagram story; below it, more designs: with your record, your heart rate, the map, your splits, the date or a QR code so people can follow you.

• The ones with a checkered background are transparent: tap one again and with «Move» you place it and resize it with your fingers.
• «Take photo» or «Your photo» puts one of your photos behind the transparent ones; «Remove photo» takes it away.
• «Copy» lets you paste them on top of a photo in your Instagram story: hold your finger on the screen and «Paste».
• «Save» puts them in your photos, «To the community» sends it to a friend or a group, and «Share» opens WhatsApp, Instagram and the rest.
• The cross at the top left closes it.
• On Android, «Share» saves it to your gallery; the first time choose the «Pictures» folder and allow it.

It's the planet in the middle of the bar. It needs an account and a nickname.

• It opens with the planet spinning. At the top, three buttons: «Compete» (box invitations, racing in pairs or as a team, and your boxes), «Find a teammate» and «Workouts». When you open it, the planet spins and the community's people appear below; your friends are folded into the «Friends» pill: tap it and they unfold, and touching the planet folds them again and shows the people in the area you're looking at. Anything waiting for your answer pulses, and its button shows a red bubble with how many.
• Tapping the planet without an account takes you to create your account (with Apple, Google or your email; with email you get a code that you type in the app itself) and, with no extra steps, to your nickname and city, which are already filled in (a nickname like «Atleta4821» and the nearest city based on your connection) and can be changed right there; tap «Join» and the map opens over your country, with the people around you. After creating your account you get «Nickname»: a free nickname already suggested, with three alternatives, and your city; «Enter», which puts you on the map (if you'd rather not appear, turn it off in Settings › Your account › Community). If you don't set a nickname, the next time you open the app you get one («Atleta» and a number, never your name) and you count on the map as «No name» in your approximate city; in Community, «Complete your profile» lets you change that nickname (once) and decide whether to show up. «Count as «No name» on the map» can be turned off in Settings › Your account › Community. If you already had the app, it's offered once, with «Compete with people around the world». And when you finish your first full race without an account, once, with «Save your races and compete with people around the world».
• The community is for ages 14 and up, the same as in Reverfit Entreno and Socio, which share it (same nickname, same friends). From 14 to 17, only your friends and other minors can see you, and an adult can only add you with your code. Your account is the same in all Reverfit apps: when you delete it (Settings › Your account) you see the apps where you use it, each with its own switch; everything from the ones you tick is deleted, and the account only disappears when it is no longer in any of them.
• When you choose your nickname you pick your city, and «Show me on the map» comes switched on: that way people near you can find you to train. If you don't want to appear, switch it off right there; you can also change it later in Settings.
• Add a friend: ask from the map. If you haven't chosen a city, the app puts you in the nearest one based on your connection (IP); change it in Settings. Minors (14 to 17) don't show on adults' map and only they have a code: to add one, Settings › Your account › Community › «Add with code», type their code and tap «Ask». If someone asks you, they appear at the top with «Accept» or «Decline».
• Your friends: in the circle, their photo; if they have none, their app's icon (8R if they're on 8Round; the dumbbell if they're only on Reverfit Entreno). On the right, the dumbbell if they're also on Entreno. The ring is pink for women and blue for men, if they show it. Tap one to open the chat. If a friend has set a record, their circle shows a little bell; it goes away when you tap them. When someone writes to you or sends you a friend request, you get a notification and the planet (and the app icon) shows the number of unread messages and requests waiting for an answer.
• In the chat, «Translate» at the top shows your friend's messages in the app's language, in the same bubble; tap it again to see them as they were written. It stays on for that conversation. It's translated on your own phone, free and without the text leaving it (on iPhone, from iOS 18); the first time it may ask you to download the language.
• «Photo», next to where you type, sends a photo from your camera roll to the chat or group. It only appears if you and the other person (in a group, everyone) are 18 or over. Every photo goes through an automatic filter first and, if it isn't appropriate, it isn't delivered. Tap it to see it full size; from there you can report it and it stops being visible to everyone. Your result image can also be sent to a friend or group with «Send to a friend or group».
• Under your messages, the ticks: ✓ sent; grey ✓✓, delivered (they opened the app); green ✓✓, read. Press and hold one of your messages to delete it for everyone or, in its first 15 minutes, edit it; it shows «edited».
• Phone notifications, with sound: messages, groups, friend requests, new posts in your city, Doubles and Relay boxes you're invited to, who's interested in your post, comments on your workouts, high fives (the first one and, at the fifth, all together), who copies your workout and, at 8 pm, your friends' records that day. Between 10 pm and 8 am they arrive without sound. The bell, to the right of «Workouts» in the top row, keeps all of that with its count: who high-fived, commented on or copied your workouts, who's interested in your post, who wants to be your friend and your friends' records. Tap one to go to it; anything new also adds to the planet's count. Each one can be turned off separately in Settings › General › Community notifications, and it applies to Reverfit Entreno and Socio too. When you read a message in any of the three apps, the others clear their notification and count.
• Invite a friend (they send you a friend request from the map or use your box's code; if they're a minor, with their code in Settings › Your account › Community): if they're new to 8Round and you become friends, when they finish their first full race you both get a month of Plus free. Whoever invites gets up to 6 months a year.
• To chat you need your date of birth: without it you can browse the map, the board and the posts, but not send or receive messages. You're asked for it when you try to write, and minor protection and chat photos (adults only) depend on it.
• In «Find a teammate», each post says when it was posted and, if the person has no photo, shows their app's icon (8Round or Reverfit Entreno).
• Messages and ads with insults aren't sent: they go back to where you typed them.
• In the chat, the three dots at the top: remove friend, block or report.
• Groups: on the «Your friends» line, tap «Groups» to see your groups (and «Your friends» to go back); on the right, «New group»: give it a name, tick the friends you want (up to 50 people) and «Create». Whoever creates it is the admin: from the group's three dots they add their friends, remove someone or rename it. Anyone can see the members, leave the group or report it. Each message shows the nickname of who wrote it; you get a notification and the unread count, just like your friends' chats. If someone has blocked you, or you them, you don't see each other's messages.
• «Workouts», the third button at the top (tap it again to go back to the planet): your friends' races and workouts, from 8Round and Reverfit Entreno. Each card shows its app icon (8R or Entreno). «High five» is the like (above it you see how many it has; tap it to see who gave them); «Copy» saves that workout to your account, even if your friend deletes it later (tap it again to remove it); on a friend's 8Round race, «Race» (with the ghost) starts with their race as your ghost. At the top, two boards: «Friends», with your friends' workouts, and «World», with the globe: spin it or tap a country to see workouts from people there. In between you'll see your milestones, «Who to follow» and the monthly challenge. Your finished races show up there on their own, without your heart rate, for your friends and for everyone; turn «For everyone» off in Settings › Your account › Community, and «Post my races» removes them completely.
• The world map: spin the planet and zoom in; below, the people in the area you're looking at, with the same circle and icons as your friends. Anyone who doesn't want to appear with their name shows as «No name», with their app's icon (8R or Entreno), nothing else; if there are fewer than 3 in their city, they count in their country. The list below only shows people in the part of the planet you're looking at. Countries, cities and towns on the map come from GeoNames (geonames.org, CC BY 4.0 licence).
• Inviting to a box: inside the box, «Invite someone»; search by nickname or tap «Search on the map» and «Pick».
• Your nickname is also your name in the ranking, it cannot be changed and nobody else can have it (capitals and accents don't matter): choose it carefully.
• For the chat background, pinch the photo to zoom and drag it to move it.

It has four buttons at the top.

• History: the calendar and all your races (see «History»).
• Badges: your showcase (see «The monthly challenge and badges»).
• Records: choose Training or Competition and then what to look at: Level1 to Level4 on top; PFT, Stations, Open and Pro below. You see how far you were from your record in each race: the shorter the bar, the closer; the green dot is your best. You can look at the total time, just the stations or just the transitions. In the PFT the run counts as one more station. Below, your record with every leg and transition in order. In «Stations» tap the button with the photo and pick the exercise and its distance or reps; on top, your best with its day and source; below, every time you did it, latest first, with its day and source (PFT, a Level, Open, Pro, Free or a single training). Competition is what you run from Compete (Open and Pro; solo, Doubles or Relay).
• Level0 (in Training, the first of the Levels; it's free): your sessions with your bests (longest continuous run, most running time, longest distance and best pace), running pace session by session and each session with its km and pace. In Heart rate, your average running heart rate session by session, how much you stayed in your zone and, for the last one, heart rate segment by segment.
• Heart rate: choose Training or Competing and the type —each level, or each single station, for example just Ski—. You'll see how your average heart rate drops race by race, time in each zone (Warming up, Moderate, Intense and Maximum), leg by leg in its zone's colour and how much you recover in each transition. The bars fill as they come on screen.
• In Heart rate you choose what to look at: each level, «PFT» or «Stations». In «Stations» tap the button with the photo and pick the exercise and its distance or reps. Every time you did it with a strap or watch shows up, wherever it came from: a PFT, a Level, Open, Pro, Free or the single station. Each row gives the day, where it came from (and which km, in a race), the time and the average and peak heart rate.
• A Free race uses your own numbers, so its best mark is only a reference: it only really compares with another identical Free race.
• «See it with example races» fills in made-up races so you can look at everything; they do not go into the ranking and are removed in one go from Settings.

It's in the Plan tab (the second one in the bar), at the top. Choose Open or Pro on the card; it also applies to your training plan.

• The first time you open 8Round it asks whether you're a man or a woman (the race weights depend on it) and where you start: «From zero» takes you to Level 0 to build your plan and do your first session; «I already run», to Train with Level 1 selected, the short race to get started, which is free. If you haven't trained yet, the next day at 19:00 you get a reminder for your first workout (three times at most, and never if «Remind me to train» is on); your date of birth, weight and height go in Settings › Your account whenever you like.
• «Create my plan», in Plan: if you don't have a race yet, a few questions: whether you've already raced (your best time) or not yet (your goal), your division, when and where your race is, how many days you train and which watch you use; «‹» on the first question closes them. That creates your training plan and, until you have a full race, the card shows «Your goal»; after your first full race it becomes your predicted time, from your own times. Then Plus appears, which you can close with «Not now, keep it free».
• Your predicted time: what you'd do today, from your latest full races at that level (if you have none, from your single stations and running pace). Below, in green, «You could get down to…»: what you'd do fixing what costs you most.
• «See your race plan» opens the plan. First, where your time is: how much you'd gain in transitions, each station and holding your running pace, from most to least, and why.
• Your target: your predicted time, «No mistakes» (fixing only what you've already shown you can do) or a few minutes less.
• Leg by leg: the time for each of the 16 legs, pace per kilometre, how long you can stop before each one and the running clock, so you know which minute you should be at.
• «Race with this plan»: the plan becomes your ghost, and during the race you see whether you're ahead or behind it.

If any data is missing it says so: nobody's numbers are made up. Seeing it is free; racing with it is part of Plus.

The weeks left until your race, built around what costs you most time.

• Where: in the Plan tab, under your predicted time, «Create my plan». Choose your race day and how many days a week you train (3, 4 or 5) and tap «Create my plan».
• How it's built (as official guides and coaches recommend): first a base, then a specific phase and finally two weeks to taper. Three weeks building a little (one more set or half a km each week) and one lighter deload week. Never two hard days in a row.
• Each week has: your weakest station (with the weight rising from 60 % to race weight), a hard session (running tired or transitions), an easy run that grows from 6 to 10 km and, depending on your days, threshold (kilometres a bit faster than race pace) and strength. Every three weeks, a simulation: half in the base and full in the specific phase; the last one two weeks out.
• Race week: three short, easy sessions, the last one two days before, and rest the day before.
• On weighted stations you can change the kilos with the ruler: if you don't have that weight, set the one you have and the reps or metres adjust themselves to do the same work.
• Strength comes in two versions: with equipment (deadlift, Bulgarian split squat, barbell row, plank) or without (squats, lunges, push-ups, burpees). Pick the one you can do.
• In strength, each set is a ring: tap it when you finish and say how it went (easy, fine or hard). Next time, the gold ring on the right shows the weight to use, with its arrow: ▲ up, = repeat, ▼ down; tap it to set it on the ruler. Without weights, it's the reps or seconds that go up. If you also train with Reverfit Entreno on the same account, the kilos start from your last session there.
• With an Apple Watch or Garmin, your wrist shows the exercise, the set, the reps and the kilos, with the exercise video where there's a scene; «Done» on the watch marks the set as «fine», and you can change it on the iPhone.
• Each session says what to do, with numbers, and why.
• «Do it now» starts it with the 8Round timer and the settings already in: for example, the Ski at 1000 m with your best mark below and the «Start Ski» button. You can start it any day, but it ticks itself off when you do it on its scheduled day. If you tapped by mistake and haven't started, «Leave the race» saves nothing.
• The session guides you: a warm-up countdown, the main block and a cool-down. Stations are done in sets (for example, Ski 4 × 250 m) with the rest counting down; the next one starts on its own at zero. The others run with the 8Round timer.
• When you finish: your best set or your time against your best, your heart rate if you wear a strap or watch, and how it felt (easy, fine or hard): that nudges what's coming a notch up or down.
• The plan adapts: a session done on another day still counts («done on Wednesday»), and one you miss moves itself to the next free slot.
• At 7:30 on training days your phone reminds you of the session; turn it off in the plan.
• Today's session (or the next one) shows in the Plan tab, with the days left, and also at the top of 8Round › Train, with its start button. «See my plan» opens all the weeks. At the top, your time in orange, your target in green, the days to go and the sessions done.
• At the bottom of the plan you can change the date or days, or remove it. Creating and seeing it is free, and so are its first week's sessions; from the second week, doing them with «Do it now» is part of Plus.
• If you race with a heart rate strap or an Apple Watch, the plan also looks at your heart rate in recent races: if you recover little in transitions (under 10 %), it adds sessions to bring your heart rate down before each station; if your first km is higher than the rest, it asks you to start below that figure; and the station that pushes your heart rate highest goes into the plan even if it isn't the slowest. In «Today», under the goal, it says in orange why that session is due, with your numbers.

Results, reports and the calendar of upcoming events. They're the same as on reverfit.com: «Read more» opens it here and «View on the web» opens the full story there.

• When there's new news you get a notification, at most one a day, and the tab shows how many you haven't seen. Turn it off in Settings › General › Community notifications › «New news».

While 8Round is open in front of you, your phone screen won't switch off on its own; leave the app and it goes back to normal.

Open them with the cog at the top. They come in folded bubbles: tap one to open it.

• Look: dark is the default, because half of this app gets read in a hall with the lights down; grey is softer; light is for training in the sun.
• Language: Spanish or English.
• Remind me to train: one reminder a day. When you turn it on, a strip of hours appears: slide it sideways and tap yours.
• Buzz on every leg: one tap when you close a leg and another when you finish the race.
• Relay bell: a ring when it's your turn, racing as a pair or a team. It's the app's only sound: it plays even with your phone on silent and doesn't cut your music. Below it, the bell volume, which rings when you lift your finger so you hear it; and «Try the alert», to hear it before you need it. There are no other sounds on purpose: in a hall you can't hear them and with headphones they get in the way.
• Share anonymous usage: the app counts which screens are opened and for how long, with a random number from this phone, not your account. Not what you write or your races. It tells us what to improve; turn it off and nothing is counted.
• Your account: your email, your city (to compare yourself with your city and country) and Plus. Under «While you race», the heart rate strap (any Bluetooth one works; you pair it once and then it connects by itself), the Apple Watch and the Garmin.
• Your photo: if you add one, people in the community who can see you see it too: on the map, in the people list, on your workouts in the feed and in chat. Minors are only seen by their friends and other minors. In the ranking you show up with your initial. If someone reports it and we review it, it stops showing.
• Community: «Add with code» (to add a minor), your code if you are a minor, and what you show in the directory. If you turn it off, you show up on the map as «No name», with your app's icon. «Ranking» puts you in it with your nickname and time, and only people in the ranking can see it.
• Chat background: the photo stays on this phone and only you see it; your friends see their own.
• Your city: just the city, no street and no GPS. Change it any time.
• GPS is only used while you run outdoors (in Level 0 and in Train › Stations › Run) and on the Apple Watch without your iPhone: it measures your pace and distance and draws your route, which is saved with that workout in your account and, if you connect it, in your Strava. Apart from that, your location isn't looked at.
• Heart rate strap: Bluetooth is only used to read it while you race.
• Bluetooth is only used for the heart rate strap.
