Habitizer

Habitizer was a small iOS SwiftUI Application built to help develop timed habits.

It allows you created timed schedules that either auto-trigger at certain times or can be started from the app.

It was built in a two stage process - a simple UI designed in Claude Design, and then a mostly autonomous build process using specifications that completed mostly without human intervention over about 48hours of clock time, with a lot of it blocked by an outage and user gates (I had the audacity to go to sleep).

The specifications and approach were chosen to make it about as simple of an iOS app as you could build: SwiftData for the data modal, no server or syncing. The only thing that ended up being a little complex was the live view of the active habit.

Part of the goal of the project was to see what the end-to-end build would look like, and where the gotchas would be. Turns out there weren't many.
