Amissa works with a variety of wearable devices that connect through Apple HealthKit, including Apple Watch, Oura Ring, Garmin, and most newer Fitbit devices.
Helpful Details:
Amissa syncs data—such as sleep, heart rate, and activity—through Apple HealthKit. Devices like Apple Watch, Oura Ring, and Garmin connect directly to HealthKit, so their data flows quickly and reliably into Amissa.
Most newer Fitbit devices can also work with Amissa, but they currently rely on paid third-party services to connect to HealthKit. This usually works, but syncing may be slower compared to devices with direct HealthKit integration. Fitbit has announced that their new app will support HealthKit directly, but we have not yet fully tested it.
Our Recommendation:
If you are purchasing a new wearable and want a reliable, affordable alternative to Apple Watch or Oura Ring, we recommend Garmin devices. Garmin offers both sporty and fashion-forward options and connects directly to HealthKit, ensuring your data flows automatically into Amissa and is available to providers like Helia.
