Knock One Off
A to-do list that shows one task at a time.
Your lock screen holds a single task, the one you're doing now. Finish it there, and a cut-paper cat pushes it off the desk while the next one slides in.

Your next task on the Lock Screen. 
A cat helps you finish.
Built for the days when ten things are open and none get done. The current task lives in a Live Activity on the lock screen and in the Dynamic Island, with a Done button that works without opening the app.
Repeating and timed tasks, undo, and optional iCloud sync. No account, no ads, no tracking. Free with 4 cats and 2 scenes, and a one-time purchase unlocks all 12 cats. Called おしねこ in Japan, in 8 languages.
