Puzzles you can finish on a bus ride, and tools that keep your data on your own phone. Built by one person with an AI agent — shipped in public, one app every couple of weeks.

Our tools keep your data on your iPhone or in your own iCloud. No accounts, no servers of ours, nothing for anyone else to read.
Every app has one job. No feeds, no streak-shaming, no dark patterns — and Pro, where it exists, is a one-time purchase.
One person and an AI coding agent, shipping a new app every couple of weeks and writing down every mistake so the next app avoids it.
Icons, screenshots, facts and a one-paragraph description — ready to paste.
