Klocky is an alarm clock that does not stop with a simple tap. To silence it, complete a mission you chooseβ€”designed to get your mind, body, or voice fully awake. Wake up with intention Choose a positive affirmation or a Bible verse and read it aloud. Make Scripture, reflection, or a meaningful morning practice part of the routine that gets you out of bed. Prefer a different kind of challenge? Klocky includes more than ten ways to prove you are awake. Choose from 10+ wake-up missions: β€’ Read a positive affirmation aloud β€’ Read a selected Bible verse aloud β€’ Match six pairs in a color memory game β€’ Solve math problems β€’ Complete squats, push-ups, or jumping jacks β€’ Walk a set number of steps β€’ Find a household object with the camera β€’ Photograph the open sky or real grass Build an alarm around your morning Set the time, repeat days, alarm sound, and mission target. Your recent wake-ups and streak help you see the mornings you have won. Wake up to your music Choose an available song preview from Apple Music through your library, playlists, or catalogue search. Listen before selecting it, then save the preview on your iPhone for offline alarms. Designed with privacy in mind Camera-based missions are validated locally on your iPhone, and mission photos are never stored. Microphone, speech recognition, motion, and camera access are requested only when a mission needs them. Whether you want a stronger wake-up challenge, a positive affirmation, a Bible-based morning routine, or a reason to move before touching snooze, Klocky helps you start the day awake and on purpose.
