The Creator

I wanted a diary. Every other app wanted to be my coach.

Every workout app I tried had strong opinions about what kind of athlete I should be and how I should feel about my numbers. I just wanted a place to write down what I did — and look back at it with a smile.

Sweat Diary is that app. It doesn't analyse you, rank you, or nudge you. It just quietly keeps your diary and gets out of the way. I built it for myself, and I hope it fits your life too.
