For Android users, the Samsung Galaxy Watch 7 emerges as an ideal smartwatch option. Alternatively, the rugged Galaxy Watch Ultra offers better battery life and additional fitness tools, catering to those with active lifestyles. Both watches feature dual-frequency GPS and a robust set of health capabilities, such as ECG and blood oxygen sensing.
The Galaxy Watch Ultra features an impressive screen with a brightness of 3,000 nits, slightly brighter than the 2,000 nits on the Galaxy Watch 7. It also supports sleep apnea notifications with only two nights of tracking needed for accurate detection. However, to fully utilize the ECG and sleep apnea monitoring, a Galaxy phone is required, although all other fitness functionalities remain compatible with other Android devices.
