An automatic upload of the completed activities to Staminity
This section describes how to set up an automatic upload of the completed activities from various sources to Staminity:
- Uploading activities from Garmin Connect
- Uploading activities from intervals.icu: Polar, Suunto, Coros, Amazfit, Huawei and others
- Uploading activities from intervals.icu: Apple devices
- Uploading activities from intervals.icu: Fitbit, Samsung and others
Uploading activities from Garmin Connect
In order to upload your activities from Garmin Connect go to the Settings and in the “Synchronisation settings” section turn on the “Garmin Connect” switch. A Garmin Connect window opens: sign in to your Garmin account and allow Staminity to access your activities. The Garmin name and password are entered on the Garmin website only - Staminity does not receive them.

After connecting, Staminity uploads your past activities. When the initial synchronisation is finished, you will receive a notification: “Initial sync has been completed. ... from ... workouts uploaded from ...” - with the date they are uploaded from. After that, every new activity will be uploaded automatically.
The “Garmin Connect Export (beta)” switch sends planned activities from Staminity to Garmin.
Disconnecting is irreversible, so the app asks you to confirm it: already uploaded activities stay in Staminity, new ones stop coming.
Please note! In order to upload your activities, Staminity will need access to information about your activities in Garmin Connect. For this purpose, when you set up synchronisation with Garmin, an access to the information about your activities will be provided to the connected users.
Settings in Garmin: Profile settings - Privacy settings - Who can see my activities - My connections.
If you change this option, your activities won’t be uploading to Staminity.
Uploading activities from intervals.icu: Polar, Suunto, Coros, Amazfit, Huawei and others
Intervals.icu has a large number of external sources. If you don't use Garmin devices, it is recommended to use this service as an intermediate upload source.
Create an account in this service and go to its settings. Then in Staminity, in the “Synchronisation settings” section, turn on the “Intervals.icu” switch: an Intervals.icu window opens, where you allow Staminity access.
Strava is not suitable as a source. Activities that came to Intervals.icu from Strava cannot be uploaded to Staminity: Strava does not allow passing its data to other services. It looks as if the activity is in Intervals.icu but does not appear in Staminity - this is a Strava restriction, not a sync failure.
Connect the manufacturer of your device in Intervals.icu directly: Garmin, Wahoo, Polar, Suunto, Coros and others.




Uploading activities from intervals.icu: Apple devices
Activities from Apple devices also come to Staminity through Intervals.icu, but by their own path. First turn on the integration with Intervals.icu - as in the section above.
If you train with Apple Watch or your activity data is collected in Apple Health, the upload is set up through the Intervals.icu companion app - there is no such option in the website settings.
- Install the Intervals.icu Companion app from the App Store.
- Sign in with your Intervals.icu account - the sign-in uses OAuth, the password is not passed to the app.
- In the app settings, turn on automatic synchronisation of activities from Apple Health and Apple Watch to Intervals.icu. The reverse upload of activity data and health metrics is set up there too.
After that, activities will come to Intervals.icu, and from there - to Staminity, if the integration with Intervals.icu is already turned on in the settings (see the section above).
Uploading activities from intervals.icu: Fitbit, Samsung and others
Here, too, the integration with Intervals.icu has to be turned on - as in the section above: activities come to Staminity from there.
If the manufacturer of your device is not among the Intervals.icu connections, activities can be passed there through the Health Sync app. It exists for Android and iOS and transfers workouts from third-party sources to Intervals.icu.
What Health Sync can take as a source:
- on Android - Coros, Fitbit, Garmin, Google Fit, Huawei Health, Oura, Polar, Samsung Health, Suunto, Withings;
- on iOS - Apple Health, Fitbit, Garmin Connect, Huawei Health. Samsung Health is not available on iOS.
Details and setup - in the Intervals.icu announcement: Health Sync now supports Intervals.icu
