who made it

Made by one person. Really.

Hi, I'm Tiago. I built trak on my own, here in Brazil, because I wanted a habit tracker I couldn't ignore — and none of them put my progress where I actually look: the Lock Screen. Every detail, from the app to the shortcut, went through my hands.

If something doesn't work for you, the email down in the footer lands straight in my inbox.
