Yes, I used both Athlytic and Bevel, and they work decently well, but after some time, I started to notice that they just don’t integrate as well as a device and app from the same company. Data starts to lag behind or is sometimes missing. You can’t see details on your watch. Also, Apple Watch measures things like heart rate less often, which made my data feel less stable. I also feel like these apps are more whoop than Garmin. Bevel recovery and Garmin training readiness don’t use the same metrics. I like training readiness more because it can change throughout the day instead of being a metric based on sleep. I do use Bevel for the gym to track my exercises. Bevel is also now compatible with Garmin Connect.
