About
Roust is the alarm clock you can't sleep through. To stop it, you finish a short mission: a puzzle that takes under a minute once you're awake, and is just hard enough while you're not.
TWELVE MISSIONS, ALL FREE
Math, Slide, Lights on, Find the shade, In order, Memory, Hue, Connect, Code, Sort, Walk and Sudoku. Three levels each. Pick one per alarm, or let Roust surprise you with a different one every morning. Try any mission tonight, nothing scheduled.
BUILT FOR HEAVY SLEEPERS
• Loud sounds that ring through Silent mode and Focus.
• Stop it from the Lock Screen without the mission and it rings again a minute later, five times by default.
• A "Still up?" check five minutes after you finish, with a louder back-up if you don't answer.
• Every ring is scheduled in advance with the system's alarm service, so it rings even if the app is closed or your iPhone or iPad restarted.
• Test it tonight: hear the real sound before bed.
• Gentle pre-alarm, a different sound each morning, or import your own.
• Naps in one tap: 15, 20, 30 or 45 minutes.
• Stuck half asleep? After two minutes you can switch to a simple sum.
A MORNING WITH A LITTLE CHARACTER
Roust the rooster comments on your game, and the tiles wake up as you do. See your streak, how fast you got up, and your last seven mornings.
