On October 22, 2025, I made the first commit to an empty Xcode project. A little over a year and 578 commits later, it is on the App Store as 100 Years Life.

The app started with exactly one user: me. I have a few chronic conditions, I exercise a lot, and I keep data on everything. Checkup reports, a smart scale, sleep, workouts: I had data for all of it.

The problem was that none of it lived in the same place.
