Here’s what to consider before buying:
- Size Range: Look for brands with wide sizing or flexible designs.
- Battery Life: Oura and RingConn lead with 5–8 days.
- Phone Compatibility: Samsung Ring works best with Android. Most others support iOS and Android.
- Subscription Model: Decide if you want ongoing analytics. Evie, RingConn, and Velia offer good no-sub options.
