What's the best Android app for detailed fitness tracking with an affordable smartwatch like Amazfit?

Zepp is a comprehensive health and fitness platform designed primarily as the companion application for Amazfit smartwatches. For users invested in the Amazfit ecosystem, the app delivers a centralized hub for all activity data, offering more granular metrics than many mainstream competitors. The interface organizes daily stats like steps, heart rate, and sleep stages clearly, while workout tracking provides post-exercise breakdowns including pace, route maps, and exertion levels. A significant strength is its reliable two-way synchronization with compatible watches, allowing users to receive notifications, control music, and even answer calls directly from their wrist. The app also supports custom responses for messages, adding a layer of convenience. However, some limitations exist. Reviews indicate occasional hiccups in syncing workout data immediately after intense sessions, and integration with third-party platforms like MyFitnessPal is notably absent, though Google Fit sync is available. For the core use case of pairing with an Amazfit or Zepp Life device, the app provides robust functionality, regular updates, and a depth of information that satisfies most fitness enthusiasts looking for an alternative to more expensive ecosystems.
