Heavy Sleeper Alarm doesn't just get louder. To stop the ring you have to do something your half-asleep brain can't fake: get out of bed, walk, scan, remember, solve. And it can check back a few minutes later, because getting up and staying up are two different things.
PICK THE MISSION THAT GETS YOU UP
• Barcode Quest: scan an object you registered in another room, like the toothpaste or the coffee tin. You have to walk there to stop it.
• Steps: walk with the phone in hand. Stand still and the count slips back.
• Sequence Memory: tiles light up in order, tap them back. One more tile every round.
• Random Text: a new random sentence every time. Type it exactly to stop the ring.
• Math: carries, borrows and times tables on a big keypad. A wrong answer brings a new problem.
• Pick Easy, Normal or Hard for each mission.
THE RULES THAT MAKE IT WORK
• The alarm shows on your Lock Screen. Its button opens the mission, it doesn't turn the alarm off.
• The sound keeps playing while you do the mission, quieter while you work.
• Stop for 10 seconds and it goes back to full volume, and your progress starts to drop.
• Stuck on one mission for a minute? An easy round takes over, so you're never trapped.
• Prefer a plain alarm on some days? Choose Sound only and get one big Turn off button.
LOUD ON PURPOSE
17 loud tones made for heavy sleepers: siren, air-raid, smoke alarm, car alarm, air horn, twin-bell clock and more. Set the volume and a 30-second fade-in, or pick Random every day so your brain never gets used to one tone.
STILL UP?
Turn it on and the alarm rings again softly 5 to 10 minutes after you finish, asking if you're up. One tap and you're done. Fall back asleep and it gets loud again.
A FRIEND WHO KNOWS
Invite a friend with a link. They record a short wake-up message in their browser, no app needed. If you miss your check-in, the app plays their voice, and if they turned on alerts, they hear that you didn't make it up.
FREE, FOR REAL
Unlimited alarms, all five missions, all 17 tones, one friend and a Still up? check are free. No account, no sign-up. Your alarms stay on your phone.
