Gravity.
A minimalist calisthenics tracker built in 24 hours.
I built Gravity because I was tired of fitness apps that feel generic and cluttered. I didn't want another standard template. I wanted an app that felt personal: designed exactly the way I train, with the aesthetic I love.
In just one single day, I went from a rough idea to a fully functional app. I documented the entire process in a video, link below.
Gravity is designed in a strict "Swiss International Style" (no rounded corners, massive typography) and handles "Hybrid Routines", mixing standard reps with EMOM intervals.
The iteration speed with Anything was so fast that I was literally making changes to the app while at the gym. I found a bug in the timer during my workout, typed a quick prompt, and it fixed and updated the app before my next set.
