The best Android alternative from my point of view presents the Galaxy Watch 4. Released in 2021, it represents a new direction for Samsung in several ways. Firstly, the design of the standard model now resembles the former Watch Active and secondly, there is a new operating system instead of TizenOS. The WearOS-based OneUI Watch performed very well in the test.
Besides the good connectivity to the phone, there is a high-quality and powerful hardware including unique tracking functions. In return, the battery life is low due to the compact case, and some tracking features are Samsung-exclusive.
