Version 3.0 has a cleaner UI. I eliminated screens and features that were never used, and would occasionally lead to bugs. By doing so, I drastically improved the user experience. Making the app simpler also means that user retention will go up. I plan to add more features shortly.
As it stands the average user doesn't really track their fitness goals quite as I do. And this realization means I have to add some micro-interactions that can help the user better understand their intended goals.
