About this app

"Full-on dieting is exhausting. But I'd like to be just a little more mindful."

Metabolog is a simple weight tracking app for diet and health care — made for exactly that feeling.

Log your weight quickly, glance at the graph, and you're done. Easy weight management that fits into your daily health routine.

**Your buddy Metabolog Man cheers you on**

Every time you log your weight, Metabolog Man has something to say. Lost weight? Gained a little? Hit your goal? Haven't opened the app in a while? He responds differently to each situation, with multiple phrases that appear at random. He never lectures you — he just quietly roots for you. If you prefer a cleaner look, you can hide him in settings.

**Keep the streak going — he gets emotional**

Hit a milestone and Metabolog Man has something special to say. We'll leave it at that.
