I sleep through every alarm
Five alarms, full volume, and you still wake up late with no memory of turning any of them off. Here's what's going on, and the setup that gets a heavy sleeper upright and keeps them there.
Most heavy sleepers don't really sleep through the alarm. They half-wake, switch it off and fall back asleep. Beyond Alarm is built for exactly this. It won't go quiet until you've done something you can only do standing up.
Why it happens
The sound usually does reach you. The problem is the few seconds after it. Waking up isn't a switch. It's a slow climb out of sleep inertia, and the review literature puts the worst of it at roughly the first 15 to 30 minutes, longer if you're short on sleep. During that time your hands work fine. Your judgement doesn't.
So a heavy sleeper's morning often goes like this: alarm, a reflexive tap, back under. Nothing about it sticks in memory, which is why it feels like the alarm never rang. A large Korean study published in PLOS One in 2026 found that morning grogginess lasted 15.8 minutes on average, and longer in people with anxiety or insomnia.
That's why more volume and more alarms only go so far. A louder alarm gets switched off just as quickly. The answer isn't to be heard more. It's to make switching the alarm off take long enough, and need enough movement, that you're awake by the time it's done. There's more on this in why your alarm stopped waking you up.
The fix: Beyond Alarm
Missions you can't do in bed. Beyond Alarm only stops when you finish a mission. For heavy sleepers, choose one that needs you upright:
- Push-ups, squats or jumping jacks, counted by the camera on the device
- Photo mission: a photo of a place you registered, like the kitchen
- Scan a code: a barcode or QR code stuck somewhere away from the bed
- Household hunt: show the camera an object from your list, which you'll have to go and find
- Walk it off: a set number of steps
Stack up to five on one alarm if one isn't enough.
Wake-up Check (Android). A few minutes after the mission, a check comes back: "Still awake?" Ignore it and the full alarm rings again. This catches the classic heavy-sleeper move of finishing the task and climbing back into bed.
On iPhone, iOS always shows its own stop slider. In Beyond Alarm, sliding it opens the mission and sets the alarm to ring again, and only finishing the mission cancels that.
No escape routes. On Android, Prevent power-off stops the power menu being used to silence a ringing alarm. Prevent app uninstall stops the app being deleted to get out of it. On iPhone this uses Screen Time, which blocks deleting any app while it's on.
Sound you'll notice. Choose a loud tone or your own music, set the volume per alarm, and add a Wake-up message, a line read aloud when the alarm goes off.
Every mission is free during the current promotion. Pro removes the ads.
Beyond Alarm
Beyond Alarm does this part for you: the alarm will not switch off until you have actually moved, and the apps you pick stay locked afterwards.
Set it up tonight
- In Beyond Alarm, tap +, then Alarm.
- Under Wake-up mission, add a physical one. Photo mission and Household hunt need a place or a list of objects set up first. Do it now.
- Add a second mission if you want. Maths after push-ups is hard to do half asleep.
- Under Alarm sound, pick a loud tone and turn the volume up.
- Tap Snooze and set a low Snooze limit, or switch snooze off.
- On Android, turn on Wake-up check and choose a follow-up time.
- On Android, go to Settings → Prevent power-off and turn it on. Then open Settings → Alarm reliability and fix anything in red. A heavy sleeper can't afford an alarm the phone has quietly shut down.
- Tap Save, then try the alarm once while you're awake.

Common questions
What is the best alarm for heavy sleepers?
One that won't stop until you're out of bed. Beyond Alarm only stops when you finish a mission, and the best missions, like camera-counted push-ups or a photo of a room down the hall, can't be done lying down.
Why do I sleep through my alarm?
Often you don't sleep through it. You half-wake, switch it off and fall back asleep without forming a memory of it. Short sleep and sleep debt make that grogginess heavier and longer.
Will a louder alarm help?
It helps you hear it. It doesn't stop you switching it off on autopilot. The fix is an alarm that needs a conscious, upright action before it goes quiet.
Does Beyond Alarm work on iPhone for heavy sleepers?
Yes. The missions work on iPhone. iOS always shows its own stop slider, and in Beyond Alarm that slide opens the mission and sets the alarm to ring again unless you finish it.
