The alarm rings, you swipe it away half asleep, and you wake up late again. SmartClock stops that: the sound only turns off after you finish a mission. MISSIONS THAT ACTUALLY WAKE YOU UP - Math: solve equations before the ringer stops. - Memory: repeat the pattern the screen shows you. - Shake: move the phone until the counter hits zero. - Squat: get out of bed and complete the reps. - Barcode or QR: scan a code you left in the kitchen. - Photo: take a picture of a spot far from your pillow. BUILT FOR HEAVY SLEEPERS Loud, escalating alarm sound that keeps rising until the mission is done. No snooze mode for people who oversleep every single morning. Repeat schedules for shift work, early flights and gym days. Difficulty levels so the challenge matches how deep you sleep. HOW IT WORKS 1. Pick a time and the days it repeats. 2. Choose the mission and how many rounds you must clear. 3. In the morning, finish the mission and the alarm stops. PREMIUM SmartClock Premium is an optional subscription that unlocks the premium features listed in the app. Terms are shown before you confirm. Set your first mission alarm tonight and stop fighting the snooze button. EULA: https://applu.me/smart-clock/eula Privacy Policy: https://applu.me/smart-clock/privacy-policy
