There's a Garmin app that connects with Sleep as Android, although I haven't had good luck with it on my Fenix watch. https://apps.garmin.com/en-US/apps/e80a4793-f5a3-44c7-bd7f-5...

Yes, they list a beta ConnectIQ (Garmin device app) app, but Garmin has some nice and more compact devices with heart rate as well (e.g. vivosmart 3) and those don't run apps.
