The story

I built On Lifting for my kids and me. When they started lifting, the apps I knew had become expensive for students, lacked Family Sharing and kept their data on company servers. I’m a solo, self-funded developer: I left enterprise consulting, learned Swift in late 2023 and have built the app full time since. I train and use the app almost every day, and many features come from my TestFlight testers’ suggestions.
