How can we help?

The app finds your last trainer and chest strap on its own. Three rings show power, cadence and heart rate; once power is live you can start. Without an FTP the app shows relative values only and cannot control the trainer.

The block and its target on top, live values in the middle, the profile with your position below. You adjust the intensity in 5 % steps. Pause and abort any time; an interrupted session can be resumed at the next start.

A short rating (effort, feel), then the review. Under "Upload to" you choose where the ride also goes. With an account it lives in wattout Cloud and on all your devices.

In the app under "Library" and on the web under Workouts you’ll find 117 workouts, the same ones the Coach plans from, named after category and level (e.g. "Load VII"). You can ride any of them or copy it into your own workouts. The library needs an account.

Build your own workouts on the web at wattout.app/app → Workouts. They live in wattout Cloud and are ready on all your devices.

wattout comes from the App Store: open wattout.app/get/ios on the device and the link takes you straight to the app. On iPad, wattout shows more numbers, and in Connected the other riders sit in a side panel.

Macs with Apple silicon run the iPad app. Install it from the Mac App Store, using the same link as for iPad: wattout.app/get/ios. Intel Macs are not supported.

The TV app comes from the App Store too: open wattout.app/get/tv on your iPhone, iPad or Mac, or search for wattout in the App Store on the Apple TV itself, signed in with the same Apple Account. Updates also come through the App Store.

You sign the TV in with your phone: it shows a QR code and a code. Scan the QR code, confirm the sign-in in the wattout app and check that the code matches the one on the TV. The TV then shows your planned workouts and the library, and the trainer connects to the Apple TV directly over Bluetooth. You can ride Connected on the TV as well; Apple Health is not available there.

wattout is available on Android as early access through Google Play: open wattout.app/get/android on the device. wattout adapts to phones, tablets and foldables.

At wattout.app/app you see your week and your rides, build your own workouts and manage your account. Riding happens in the apps.

The phases are Base, Build, Peak and, with an event, Taper, otherwise Test; lighter recovery weeks are worked in. With an event 6 to 12 weeks out the plan ends with the event week; without an event it is always 12 weeks. The workouts come from the library and keep fixed names, so you recognise sessions.

After every ride and every rating the Coach adjusts the coming seven days automatically, and also when your recovery changes noticeably (at most once a day, and only if you rode in the last 14 days). The dashboard shows why, for example "adjusted this week to your recovery". The start date and the phases never move. If you withdraw your consent to AI planning, your plan stays but stops adapting.

The Coach does not re-plan missed sessions by itself. A tap on "Neu planen" (re-plan) plans again from today, no new approval needed.

Only your first plan, or a changed goal or event date, produces a new 12-week plan for you to approve; everything else the Coach applies directly.

At most two hard sessions a week, at least 48 hours between them, never more than four days in a row, recovery weeks built in, never above your weekly budget. The server checks these rules on every plan and every adjustment, wherever it comes from.

No, not in the introductory phase: until 28 February 2027 the Coach is free for everyone, including all Premium features. We will tell you in good time before that changes.

Under the two-people icon you create a session, pick the workout and share the link or the code. A tap on the code copies the invitation; open invitations last seven days. Whoever joins can ride the suggested workout, their own next planned one, or any other.

In the lobby you decide per session what the others see: progress, relative power, Pain, cadence, heart rate, absolute watts. Heart rate and absolute watts are off by default.

The host starts once they and at least one other rider are ready. Anyone not ready at the start doesn’t ride along this time and sees a notice.

After the ride, what each rider did stands side by side. Different watts. Same pain.

On iPhone, iPad, Mac, Android and Apple TV. On iPad and large tablets the other riders sit in a side panel. On Apple TV you join with the code or pick the session in the CONNECTED row on Today; creating and inviting happens in the app.

Sleep, resting heart rate and HRV, plus, if available, your body weight as context, each for the last 30 days and going forward. Whether your completed workouts from other apps are included is a separate choice. This data reaches the wattout server only with Premium, and only the Coach uses it.

After every ride you choose under "Upload to" whether it lands in Apple Health or Google Health Connect as a workout. Writing happens from your phone, not from the Apple TV. Change the preselection under Settings → Completed workouts.

Garmin does not write workouts to Google Health Connect, so on Android the Coach does not see your Garmin sessions. You can bring your wattout rides to Garmin Connect as a FIT file by email.

You can withdraw these permissions any time in Apple Health or Google Health Connect.

You have a Wahoo KICKR Core in the basement and a Garmin watch on your wrist. The workout comes from the Coach, the library or your own. During the ride the KICKR holds the power targets while wattout shows block, target, power, cadence, heart rate and Pain. Afterwards the Garmin uploads its own recording to Garmin Connect. If you would rather see the wattout ride there, send it to yourself as a FIT file by email and upload it to Garmin Connect. Rating and figures stay in wattout.

Many training apps want birth date, weight and sex. For planning indoor training by FTP they add little: targets are relative to your power, and the Coach reads load from your rides and your heart rate. At the same time they are data that identify a person easily, and with sex we do not want to put anyone in a box. We keep to data minimisation: what we do not need, we do not ask for.

What the Coach uses, optionally, is deliberately coarse: an age band in five-year steps, because age affects recovery and how intensity is built up, and the maximum heart rate, so the pulse can enter Pain. If your body weight is in Apple Health or Google Health Connect and you share it, the Coach uses it purely as context. Everything works without these, just less individually.

As early access through Google Play until the app is released in the regular Play Store: join the Google group, activate early access and install the app. The three steps are on wattout.app/get/android. Updates then arrive automatically through Google Play.

If it speaks Bluetooth FTMS with ERG mode, yes. Most current smart trainers do. wattout doesn’t support ANT+.

No, but it’s worth it: with heart rate and your maximum heart rate, Pain gets more accurate. wattout pairs Bluetooth chest straps.

Not to ride: trainer control, recording and FIT export work without one. You do for the library, wattout Cloud, Connected and the Coach. You sign in without a password, with a code sent by email.

Your ride is recorded every second on the device and restored after a crash; you can resume an interrupted session at the next start. With an account every ride arrives in wattout Cloud exactly once.

Riding, your own workouts, the library, Connected, wattout Cloud, the export to Apple Health and Google Health Connect and the FIT file by email are free. The Coach is free in the introductory phase too, until 28 February 2027, including all Premium features.

Because it adds nothing to structured training and costs a lot. Virtual worlds need big studios, servers for thousands of concurrent riders, and are financed by subscriptions of 15 to 20 euros a month. For an interval session what counts is that the trainer holds the targets exactly, that you see your numbers clearly, and that the ride ends up where you analyse it. That is what wattout does, without a graphics card and without a subscription for scenery.

With a plan. Deciding every day whether and what to ride wears you down fast. The Coach takes that decision off you: the next workout is set on the dashboard, matched to goal, time and your last session. You only have to get on. Add Connected: agree on a time with friends, each on their own trainer, and the appointment holds.

No. wattout is deliberately not a closed system. We support proven platforms such as Apple Health, Google Health Connect and the ecosystems of the wearable makers instead of replacing them. You can send every finished ride to yourself as a standard FIT file, to your account’s email address, and upload it to Garmin Connect, Strava, Komoot and the like if you want. Your calendar stays your calendar. Stop tomorrow and you lose nothing.
