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 meters, 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.

At the top choose Compete, then Open or Pro, and tap Individual, Doubles or Relay; when «Start» appears underneath, tap it again. What you run here is what counts for the ranking.

• Doubles and Relay happen in boxes: you create one with a day and time (and a name, if you like) and invite friends, anyone in Community or with their code.
• When you're all in, each of you taps «Start» and a countdown appears on every phone at once.
• As in the official rules: in Doubles you run the 1000 m together and split the stations; in Relay each of you does two 1 km laps with their station.
• The white ghost between Open and Pro is for racing your best time, another of your races or a friend's (see «Race against the ghost»).
• A box nobody races deletes itself 6 hours after the agreed time.
• If anyone changes who does what, you all have to tap «Start» again.
• In a Pro box, only people who have Plus and show it appear to invite; send the code to anyone who doesn't show it.

You can take the race on your wrist. It's all in Settings › Your account › While you race.

• Apple Watch: nothing to pair. If 8Round is on your watch, the row says «Ready»; if not, it tells you how to install it from the Watch app on the iPhone. Before you start, open 8Round on the watch.
• Garmin: you need the 8Round app on the watch (from Garmin's Connect IQ store) and Garmin Connect on your phone. On iPhone, tap «Garmin watch» and pick your watch in Garmin Connect, only the first time. On Android it finds it by itself.
• On both, the watch shows the leg, the time, the ghost and your heart rate, and the big button (START on the Garmin) does the same as «Start» and «Done» on the phone. In Doubles and Relay it buzzes when it's your turn, and the button is off when it isn't.
• The watch's heart rate counts like a strap's: you see it leg by leg, by zones, and in your Progress.
• «Video on the watch» (Settings › Your account › While you race): behind the numbers, Hugo or Nora moving through the station; turn it off for a still photo, which uses less battery. With your wrist down it always stays still.
• Heart rate strap: any Bluetooth chest strap or band works (Polar, Garmin, Wahoo, Coros…), and also any watch that broadcasts heart rate. Put it on and wet it a little before searching, as it won't read dry; then tap its name to pair it.
• Your max heart rate (Settings › Your account › While you race): it sets the zones and the calories. At first it comes from your age. If in a race you hold a higher heart rate for five seconds in a row, the app keeps that one, your real one, and shows «Measured» with its date; a one-second spike doesn't count, it's usually a misread. If a doctor or a stress test measured it, type it there and yours wins; delete it to go back to automatic.

It's in Progress › History, the first button. It's the calendar: days with a race or a plan session are orange. Below are your races, by month; tap one to open it. The plan's set sessions show with a PLAN tag and their best set against your record; the ones you did with the timer are already there as races.

• The summary: the time, how long you ran, how long at stations and in transitions (what HYROX calls the Roxzone), and each leg with how long you stopped before it.
• With a heart rate strap, also your average and peak heart rate, calories, time in each zone and how much you recover in each transition.
• At the top of the summary, «Share my race» (see the next section).
• At the very bottom, «Race against this one» and «Delete this race».

It's racing against a race already run, as if that person were next to you.

• Where: in Compete, in the Open and Pro row, the white ghost button in the middle. It works for whichever level you have selected, Open or Pro.
• Tap it and choose who to race: your best time at that level, another of your races (a list appears, fastest first) or a friend (pick the friend and one of their races). Anything not available yet is grayed out.
• Also from Progress › History: open a full race, scroll to the bottom and tap «Race against this one».
• While you race, under the top clock it says how far ahead (green) or behind (red) you are. It updates as you finish each leg.
• At the end, the summary says who won, by how much and in which leg you gained or lost most.
• «Against the world record»: your category's, by your sex and age group at that level (with no date of birth in your profile, the overall one), with the real splits of that race. Records as compiled by Rox Lyfe on 3 October 2026; splits from hyresult.com.

Pro still needs Plus.

In Community, the orange «Find a teammate» button opens an ad board to find someone to race or train with.

• Post your ad: Doubles (mixed, men's or women's) or Relay for a real race, with its city and date; or Train together, no race, just where you train.
• The app sets your level: your best time in that division or, if you don't have one yet, your predicted time. It can't be typed in, so nobody inflates it and similar levels find each other.
• Has your partner or a teammate dropped out? Tick «Urgent: someone dropped out» when posting: it shows first and in red, and the «Urgent» filter shows only those.
• On other people's ads, tap «I'm interested»: they get a notification, a friend request and a message with your interest. If they accept, you can message each other in Community.
• Filter by Doubles, Relay or Training, by category, by Open or Pro, by city or by «Level similar to mine».
• Nobody sees your phone or email. Race ads disappear after the race and training ads after two months. You can have three at a time and remove them whenever you like; long-press one to report it.

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.

• 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 kilometer, 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. It's 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».
• Each week brings its sessions: your weakest station, running tired, fast transitions, an easy run and, every three weeks, a simulation with your plan. The last week is easy, so you arrive fresh.
• Each session says what to do, with numbers, and why it's due.
• «Do it now» starts it with the 8Round timer and the settings already in: for example, the Ski at 1000 m with your best 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 the day it's due 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. It's 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.

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 gear 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; gray is softer; light is for training in the sun.
• Language: Spanish or English. In English, the exercises carry the names athletes use (Sled Push, Wall Balls, Farmers Carry).
• 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.
• 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: only your friends see it, in your list and in chat. On the map, the directory and the ranking you show up with your initial.
• Community: your code so people can add you, and what you show in the directory. If you turn it off, you show up on the map as a gray dot with no name. «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.
• Heart rate strap: Bluetooth is only used to read it while you race; where you are isn't stored.
