Amazfit Active 3 Premium vs Motorola Watch Ultra: which should you buy?
Get the Motorola Watch Ultra if you use an Android phone. It brings Polar's fitness and sleep coaching to a big, bright watch, and on Android it is the pick between these two. The Amazfit Active 3 Premium is the better buy for an iPhone owner and the cheaper watch for anyone.
Who should get the Motorola Watch Ultra
Get the Motorola Watch Ultra if you use an Android phone and want fitness and sleep coaching from a sports specialist. Motorola builds its fitness tracking and multi-stage sleep tracking on Polar's tools, with dual-band GPS for workouts. We have not confirmed how well it works with an iPhone, so iPhone owners should look elsewhere.
Who should get the Amazfit Active 3 Premium
Get the Active 3 Premium if you want a light everyday watch that takes running seriously. Amazfit gives it built-in running workouts, coached plans from a 5K to a marathon, and running power, plus heart rate, blood oxygen, skin temperature and sleep tracking with no subscription. It also carries free offline maps with turn-by-turn directions. On an iPhone it works with limits, so some features that need deeper phone access stay on Android.
The differences that matter
The screens are close, at up to 3,000 nits against 2,700 nits. Neither will wash out in the sun.
The real split is software. The Motorola leans on Polar's training and recovery tools, which many athletes trust, while the Active 3 Premium runs Amazfit's own coaching. Both track sleep, heart rate and workouts.

On Android, pick the Motorola Watch Ultra. On an iPhone, the Amazfit is the safer choice.
