WAKE UP is the alarm that won't stop until you've done something. beat a game, do push-ups, or photograph the sky to silence it. closing the app, swiping it away, or sliding to stop? that just sets another alarm. if you set five alarms and sleep through all of them, this is the alarm clock built for you. a normal alarm only asks for one thumb. WAKE UP needs your brain and body online before the sound stops. MADE FOR YOU IF • you stack alarms 5 minutes apart and still oversleep • you snooze on autopilot and don't even remember doing it • you've deleted other alarm apps because they were too easy to beat • you work early shifts, open the gym, or have an 8am class • you want a morning routine that survives past week one HOW IT WORKS 1) set an alarm with one or more challenges 2) alarm goes off 3) complete the challenge to silence it 4) start your day with a win instead of a snooze 15 CHALLENGES BUILT TO ACTUALLY GET YOU UP • flappy pigeon: clear a random number of pipes • bunny dash: hop across roads, rivers and railways • dino run: survive the jungle by dodging obstacles • shadow slayer: defeat kage • fruit shinobi: slice the fruit mid-air, spare the bombs • tennis: win the morning rally against a live rival • math: solve a set of problems • barcode hunt: hunt down and scan a barcode • snap the sky: capture the sky • make bed: tidy up your bed • object hunt: hunt down a random item • photo booth: take 3 pics feeling yourself • push-ups: complete a random set of push-ups • squats: complete a random set of squats • dance: dance until the hidden timer runs out stack more than one on a single alarm for a rough morning, or let random pick for you. NO CHEATING, NO SHORTCUTS • lock in mode prevents deleting the app while an alarm is going off • the alarm doesn't stop until the challenge is done, no exceptions • AI verifies your photo challenges, so a shot of your ceiling won't pass CLIMB THE LEAGUE • every wake-up banks XP, dismiss fast and keep a streak for bonus XP • climb from bronze all the way to diamond • each week your group settles who moves up and who slips back: top 10 promote, bottom 5 drop • race real early risers worldwide and watch your world rank climb STREAKS & GEMSTONES • beat the alarm and the day counts. your streak climbs. if you stop, you lose the streak. • 7 gemstones at 1, 3, 7, 14, 30, 100, and 365 mornings. each stays hidden until the morning you unlock it • a full day with no alarm set, weekends included, costs your highest gem. one more WAKE UP brings it back • the longer it gets, the less you'll want to snooze. that's the point WAKE UP WITH FRIENDS • see when friends crush their morning challenges • comment on each other's WAKE UPs • keep streaks going together SLEEP TRACKING THAT ACTUALLY HELPS • syncs with apple health for sleep duration, bedtime, and wake time • see your sleep score every morning • track consistency week over week SIRI INTEGRATION • say "hey siri, set an alarm for tomorrow at 7am and make the challenge flappy pigeon in WAKE UP." • siri only confirms once the alarm is actually scheduled ALARM SOUNDS YOU'LL ACTUALLY GET UP TO • viral sounds, brain rot, and more • upload your own sound file if none of them hit 15,000+ people use WAKE UP to get out of bed. join them tomorrow morning.
