Band quality was mixed: one reviewer disliked the thick rigid strap, while others liked the secure, quick-release design.

Companion app quality was split: Apple Health was praised by one reviewer, while another disliked fragmented data across apps.

Companion app quality was mixed, with decent connectivity but route editing, waypoint categories, and Zepp route creation needing polish.

Fitness tracking accuracy was praised, especially for workout pulse, path snapping, GPS syncing, and broad activity tracking.

Fitness accuracy looked good where reviewers discussed tracked sport detail and elevation, but the broader evidence base was thinner than for GPS or heart rate.

Touchscreen responsiveness was praised for accurate, hassle-free input and joy-to-use responsiveness.

Touchscreen responsiveness was mostly good, though one reviewer found it overly sensitive and in need of subtlety.

Voice assistant quality improved with on-device Siri and faster responses, but dictation and offline capabilities still had occasional limits.

Voice assistant feedback was positive, with Zepp Flow described as useful and capable of offline watch control.

Comfort was mixed: some found the Ultra 2 comfortable, while others noted crown irritation, tugging, or adjustment time from the large case.

Comfort was the main hardware drawback: most reviewers found the watch bulky or uncomfortable for sleep, though one hands-on review found it comfortable despite the size.

Brightness was praised for the 3,000-nit upgrade and outdoor readability, though a few reviewers found the improvement subtle in practice.

Brightness was excellent, with reviewers finding the screen crisp and easy to see outdoors.

Reviewers found the Ultra 2’s health tracking credible for sleep-related disturbances and general health metrics, with heart-rate-linked data repeatedly described as accurate.

Reviewers found the newer sensor and overnight health data generally credible, though evidence focused on broad health metrics rather than every individual vital.

Bluetooth connectivity received limited but positive evidence around cycling accessory support, especially power meters.

Bluetooth/app connectivity was reliable in the Live Science test, with no disconnects or transfer problems reported.

Reviewers strongly praised the large workout library, especially niche outdoor and adventure modes, while noting most people will use only a subset.

Call handling was strong in the evidence, with a test call described as clear, loud, and phone-like to the person on the other end.

Call handling was viewed as solid, with wrist calls, louder speaker output, and audible prompts reducing phone reliance.

Coaching features improved with Training Load, perceived effort, and structured workout support, though evidence suggests they still sit below specialist training platforms.

Coaching was received positively, with Zepp Coach and training advice described as helpful for planning and guidance.

Materials quality was strong, with reviewers praising titanium, premium feel, and classy finishes.

Materials felt premium, with reviewers calling out the titanium back and more durable materials.

Charging convenience was helped by multi-day use and quick top-ups, though reviewers still noted the need to manage charging.

Charging convenience was positive where mentioned, thanks to the charging puck working with common USB-C cables.
