I have used many fitness app such as fitbit, Microsoft health, Google fit, Nokia fitness app, Samsung health but nothing could really better this UP app. It is sad to know that jawbone closed its fitness band but UP3 band is still advanced for sleep analysis. The UP app gives insight based on our activity. It will gives motivational words, ask us to take water if resting heart rate is down, keeps us informed about drawback in the exercise we do and provides alternative. This is definitely a milestone app that was underrated. It uses very good machine learning.. Great job
