Instead of using third party apps for a todo list, I recently wrote myself a utility - a background process to reschedule iOS Reminders I don't get to, make sure every reminder I create actually gets a scheduled date/time, and to deconflict reminders from calendar entries if I get an overlap.

It took less than 90 minutes using claude code, I have a testflight I've shared with friends for feedback, and I'll probably put it out there for a dollar once I add a couple more settings.

The built in UIs, syncing, and integrations are really good. It took me a while to realize I didn't need another todo list app, just to tweak the built-ins.

It's a fairly radical idea that AI can (and should!) be doing things invisibly with existing platforms and avoid the whole nightmare of UI development.
