YOUB connects to 14 watches, bike computers, rings, scales and training apps: Apple Health (iPhone), COROS, Garmin, Hammerhead Karoo, Hevy, Intervals.icu, Oura, Polar, Rouvy, Strava, Suunto, Wahoo, Whoop and Withings. Connected sources bring in your recorded activities and, depending on the device, your sleep, heart-rate variability (HRV), resting heart rate and recovery scores. When you connect a provider, YOUB also imports a stretch of your past training, so your training load curves and the coach start from your real history. Garmin, Wahoo, Suunto and the Hammerhead Karoo additionally receive your planned sessions as structured workouts.

Supported Providers

Provider Activities Sleep & recovery History imported Planned workouts to device
Apple Health (iPhone) Workouts Sleep, HRV, resting heart rate Last 365 days No
COROS Workouts with full activity files Sleep and sleep score, HRV, resting heart rate, daily stress Last 90 days No
Garmin Activities with full activity files Sleep, HRV, resting heart rate, Body Battery, all-day stress Last 30 days Yes
Hammerhead Karoo Rides None Last 365 days Yes (cycling)
Hevy Strength workouts with sets, reps and weights None Last 365 days No
Intervals.icu Activities HRV, resting heart rate, weight Last 180 days No
Oura Workouts (as summaries) Sleep, HRV, Readiness Last 60 days No
Polar Training sessions Sleep, nightly HRV (Nightly Recharge) None: only sessions after you connect No
Rouvy Indoor rides None Last 365 days No
Strava Activities None Last 730 days No
Suunto Workouts Sleep, HRV, resting heart rate, recovery (Resources) Last 60 days Yes
Wahoo Workouts None Last 60 days Yes (running and cycling)
Whoop Workouts (as summaries) Sleep, HRV, Recovery, strain Last 60 days No
Withings None Sleep, weight, body composition Last 365 days No

A watch or band that records sleep and recovery gives the coach the fullest picture. Platforms such as Strava, Rouvy and Hevy add activities only. Whoop and Oura workouts arrive as summaries without a recorded file, so their Load Score is estimated from heart rate (see How YOUB Calculates Training Load).

All-day stress comes only from Garmin and COROS. If neither is connected, the stress chart stays empty.

Connecting a Wearable

Wearables connect under Settings > Wearables, or in the wearables step of the account setup. Tap Connect next to a provider, sign in on the provider's page and allow access. You return to YOUB and the provider shows Connected. The first activities can take a moment to appear, usually within about half an hour.

A few providers have an extra step:

  • Garmin: grant the "Historical Data" permission on the Garmin consent screen, otherwise your past workouts cannot be imported. Garmin also asks separately for permission to receive workouts; that permission is what puts your planned sessions on the watch.
  • Hevy: Hevy connects with an API key and needs an active Hevy Pro subscription. In Hevy, open Settings, then Developer, create an API key and paste it into YOUB.
  • Apple Health (iPhone only): iOS asks which data YOUB may read. If access was not granted, open the Health app and enable it under Sharing > Apps > YOUB.
  • Strava: once connected, the Strava entry offers a Trained by YOUB switch that adds "Trained by YOUB" to the description of new Strava activities.

When a provider withdraws access (for example after a password change on the provider's side), the wearable shows Reconnect needed. Reconnecting takes a few seconds and keeps your existing history.

Without a connected provider you can still send a recorded .fit file to the coach in the chat or over WhatsApp, which is also the way to bring in a single older workout.

Recording with the YOUB App

Without a watch, you can record a run, walk or ride with your phone in the YOUB app. The phone records the GPS track, distance, time and pace. It records no heart rate, and the phone's altitude is not used, so a phone recording shows no elevation gain and no grade-adjusted pace. A run or walk recorded this way still gets a Load Score from its pace; a ride gets none (see How YOUB Calculates Training Load). When a connected watch recorded the same session, the watch recording counts instead.

How Much History Is Imported

When you connect a provider, YOUB imports your past data once, going back the number of days shown in the Supported Providers table. After that first import, new data arrives as you record it. Older data stays with the provider.

  • Garmin limits the history import to the last 30 days. Reconnecting Garmin does not extend that window.
  • COROS serves only about the last three months of data, so the COROS history import covers about 90 days.
  • Polar imports no history: only sessions recorded after you connect arrive.
  • Rouvy holds rides from 2023 onward.

If you want the coach to see one specific older workout, send its .fit file in the chat.

Several Providers at Once

You can connect as many providers as you like, for example a Garmin watch together with Strava and a Whoop band. When the same workout arrives from two sources, YOUB recognises it as one workout and it counts once: one entry in your training log, one Load Score and one link to the planned session. You do not need to delete anything yourself.

Under Settings > Wearables, Provider priority lets you choose which source YOUB prefers when an activity or a health metric arrives from more than one provider.

Disconnecting a Wearable

To disconnect, tap Disconnect next to the provider in Settings > Wearables and confirm. YOUB removes its access to the provider, and the activities and health data already synced stay in YOUB unless you ask for them to be deleted (see Privacy and Data).

Some providers behave differently on disconnect:

  • Apple Health: disconnecting stops syncing and deletes the Apple Health data YOUB has stored for you.
  • Garmin: the planned workouts YOUB sent to your Garmin account are removed.
  • Hammerhead Karoo: YOUB's access is also withdrawn at Hammerhead, which removes the workouts YOUB put on the Karoo.
  • Wahoo, Suunto: planned sessions stop being sent to the device.

Health Data and the Morning Check-In

The coach's morning check-in is triggered by last night's sleep arriving from a sleep provider: Garmin, COROS, Polar, Suunto, Whoop or Oura. Apple Health and Withings sleep appears in the app but does not trigger the morning check-in. The coach reads your sleep, HRV, resting heart rate and, where the device provides one, a readiness or recovery score (Garmin Body Battery, Suunto Resources, Whoop Recovery, Oura Readiness) and adjusts the day's advice to it.

The message after a finished workout needs any connected source that delivers activities. Both messages can be switched off under Settings > Notifications (see How YOUB Works).
