Getting started
You'll need Android 9+, watchOS 11+ and a compatible iPhone for the initial watch setup. The Android app and Watch companion must be installed separately. Installation links will appear on the homepage when available.
- Set up your Apple Watch with an iPhone, install the companion app and allow access to workout data.
- Sign in to Swimiyo on Android and scan the connection code on your watch.
- Choose an existing swim workout on the watch and upload it. Then refresh your workouts on Android.
After setup, the watch only needs internet access to upload. You don't need an iPhone for everyday syncing. Resetting or re-pairing the watch may still require one.
Swimiyo does not pair Apple Watch directly with Android.
Common questions
I can't find a workout
Check that the swim was recorded, then review the companion app's health data permissions.
The connection code doesn't work
Check both devices' internet access, refresh the code on your watch and try again. Don't share the code.
A new workout hasn't appeared on Android
Check whether the watch finished uploading. Reconnect and retry if needed, then refresh Android using the same account.
Heart rate or other metrics are missing
The workout may not contain those samples, or the app may not have permission to read them. Missing data doesn't mean zero.
Which workouts should I compare?
Choose similar strokes and pool lengths. Check the comparison distance and whether the pace includes rests.
Can I use it offline?
You can view cached workout details. Uploads, new workouts and account actions need internet access.
Is the replay a video?
It simulates progress from length data. It isn't video footage or a GPS track.
How do I delete my account?
Go to Account Security and choose Delete account. See the account deletion page for details. Uninstalling the app does not delete cloud data.
