I build things I actually want to exist.
Kirok — My alarm goes off at 4:20 a.m. I head to the gym at 5:00 a.m. I've tried countless fitness apps — some were really good — but none of them quite felt like mine. So I decided to build one myself, shaped by my own experience and feedback from friends who are just as passionate about workout.
DoEveryday — I like having a routine. I wanted a simple place to log mine, and I was curious what other people are quietly and consistently doing every day. I built this hoping it would encourage anyone trying to turn even the smallest habits into something that sticks.
Mise (pseudonym) — A friend with 10 years in the hospitality industry shared a problem he'd been sitting with for a long time. So we decided to build something about it together.
