This has been fixed in version 4.1, which was built for watchOS 26 and fully supports Ultra 3. Please update and let us know if you run into any issues!

Great for which hand

Works great and not complicated to set up getting a good distance nearly 10 inch from a small magnet detection 👍

Superb ♥️♥️♥️

Works very well.
Lots of adjustments
Don’t forget about the stealth mode (stealth clock display while in use. Check instructions for using this feature).
Highly recommended by me - Charlie Dent.
