This release does not have a Play Store Description, so we grabbed one from version 3.1.5:

Not only an APP for smart watch, but also a service system for personal data, this is Lenovo Watch. It focuses more on personal motion data, calculating and extracting personal efficiency & health management, personal preference, life & work motion by data collecting, filtering, analyzing, feedback, summarizing, comparing and interacting. To a certain extent, Lenovo Watch can provide users intervention suggestion for time management, and serve the individuality much better with the big data.
