Ever dismissed an alarm without remembering it? CrazyAlarm does more than make noise. When your alarm rings, finish the challenge you selected before it stops—so your body and brain have a reason to wake up. CHALLENGES THAT GET YOU AWAKE • Movement: Squats, high knees, marching in place, raised hands, nodding, head shaking, and mouth opening • Math: Solve increasingly demanding arithmetic questions • Memory: Watch the highlighted tile and tap the matching position • Random: Get a different movement, math, or memory challenge when the alarm rings • No Challenge: Prefer a regular alarm? Use a simple slide-to-dismiss control KEEP YOUR EYES OPEN Optional eye-open detection keeps challenges active only while you are alert. Natural, brief blinks are ignored. If your eyes remain closed, movement counting, answers, and gameplay pause until you are ready to continue. PRIVATE, ON-DEVICE DETECTION Movement and face-state detection use Apple's Vision framework and run entirely on your device. The front camera starts only during a challenge and stops as soon as you leave. CrazyAlarm does not save or upload photos, videos, or camera frames. RELIABLE SYSTEM ALARMS Built for the system alarm capabilities of iOS 26, CrazyAlarm can alert you on schedule while the app is in the background. Allow Alarm access when creating your first alarm. A GENTLER WAY TO WAKE • Gradually increasing alarm volume • One snooze per alarm to prevent endless delays FLEXIBLE SCHEDULING AND WAKE STATS Choose the time, repeat days, sound, vibration, snooze length, challenge type, and difficulty. Wake Stats records challenge results and completion time, with a simple calendar for reviewing your routine. Don't just hear your alarm. Wake up, then start your day.
