Garmin companion app

The STAmina Companion App turns your Garmin watch into a heart-rate sensor while you train with the STAmina phone app. It works with Garmin Descent™ Mk2 and other Garmin watches that support Connect IQ apps.

Your watch may have an SpO₂ sensor, but Garmin doesn’t make real-time SpO₂ available to apps, so STAmina shows heart rate only. See why there’s no real-time SpO₂ from watches.

Requirements #

  • STAmina Apnea Trainer 6.5.0 or later on your phone
  • The Garmin Connect™ app installed on your phone, with your watch connected and active: you’ll see a green dot next to the watch icon in Garmin Connect.

  2. In STAmina on your phone, open Settings → Devices → Add a new device → Smart watch.
