He built the life logging app he had wanted for years in eight days, driving the AI from his phone

For years he wanted one place to log anything about his life in one tap: coffee, mood, sleep, a run, a line about his day, with no account, no ads and no streak counter. Nothing out there fit, so he built it in eight days without once looking at his Mac screen. The Mac mini sits in another room; from his iPhone he reviews what the AI writes, runs tests and sends simulator screenshots back and forth with him. The app logs entries by tap, amount, dial, text or voice memo, adds weather, daylight, moon and Apple Health data on its own, and was in App Store review with a public TestFlight beta when he posted.

This only partly worked. Read what happened before you try it.

How it works

  1. Set the AI up on a Mac mini in another room
  2. Direct it from his iPhone for eight days
  3. The AI writes the Swift, runs the tests and sends simulator screenshots
  4. He reviews and gives feedback from the phone
  5. Submit to the App Store and open a TestFlight beta

Why it’s worth knowing

The whole build happened with the computer in another room. The developer never saw the machine screen once; the phone was the entire workshop.
