Curio

A daily check-in app. Tap once to log your habit. Sessions run under two minutes.

A word puzzle that resets each round. Play one round or ten — it never asks for more.

A trivia card game with no timer pressure. Three questions, then done — pick it up again whenever.

A one-minute breathing pause. No setup, no account. Open it and it starts.

Built around quick resets

Every app here closes cleanly. No mid-session cliffhangers, no daily streaks held hostage. You decide when a session ends — the app is ready again the next time you have a spare moment.
