Polar Loop Screen-Free Health Band
Pros
- No subscription: full Polar Flow app access from day one
- Screenless 29 g band with 24/7 heart rate and sleep tracking
- Up to 8 days of battery life
Cons
- No screen, so all data lives in the phone app
- Wrist band rather than a ring or mat, which some sleepers find less comfortable at night
