Made an app for Android to replace most of my spreadsheets:

It doesn't cost anything, no ads or in-app-purchases or anything, I don't make money off this, etc.

Mostly just curious what you guys think about the functionality. You can track food, lifts, arbitrary metrics, progress pictures, etc. There are also several calculators for things like macros, calories, and your TDEE (including an option to use your own data over time), which can help guide you into how to make adjustments in order to maintain your loss/gain rates.

Anyhow, I hope you find it helpful.
