Health tracking is generally viewed as accurate and useful, especially around sleep and overnight recovery patterns.
At least one reviewer explicitly said the watch is more accurate than its predecessor for exercise and sleep tracking.
Heart rate accuracy is one of the M2's stronger areas for many workouts, but multiple reviews still recommend a chest strap when precision really matters.

Menu navigation is generally easier and more organized than before, though some reviewers still disliked the digital bezel behavior.
Music controls are useful for basic phone playback control, but they remain simple and depend on the phone being nearby.
Music controls are easy to access and part of the normal smartwatch feature set.

Third-party app support is a plus, with reviews specifically mentioning services like Strava and broader export options.

The M2 has no touchscreen, so responsiveness on that front is simply not part of the experience.
Touch responsiveness was repeatedly praised, though one reviewer found the touch bezel overly sensitive.
The user interface is usually described as clear and easy to understand, though still somewhat utilitarian and not always fast.
The refreshed interface, tiles, and Now Bar were widely praised for making the watch easier and faster to use.
