The best alarm apps for heavy sleepers
Most heavy sleepers have already tried the loud option, and the loud option is why they're reading this. A big sound gets absorbed into the dream. Something you have to finish does not.
In short
Tock is the best alarm app for heavy sleepers: it rings on AlarmKit, so it gets through silent mode and a Focus, and it keeps ringing until you finish a small task. Alarmy is the real rival and the better pick if you want the widest set of dismissal tasks or a free tier to test the idea on.
What decided the order
- Whether it still rings when the phone is silenced, inside a Focus, and with the app closed for eight hours.
- Whether stopping it takes a task you have to complete, rather than a bigger button.
- How easily you can defeat it half asleep, on purpose or without remembering.
- What it costs, and whether there is a free way to test the approach before you pay.
Tock
Best for waking up on the first alarm
Tock's alarm is built on Apple's AlarmKit, so it rings on silent, through a Focus and with the app closed, on the native full-screen alert rather than as an app playing audio in the background. It keeps ringing until you solve something: maths, a phrase, a grid of tiles, a set of steps counted by the pedometer, or a photo of a spot you saved. There are nine of these missions across mind, body and place, and they are on by default, so the hard version is what you get without going looking for it.
The catchThere is no free tier. You get a 3-day trial, then it's from $39.99 a year, and it only runs on iPhone.

Best range of dismissal tasks
Making you complete a task before the noise stops is the whole identity of the product, and it has more of those tasks than anyone, including some Tock does not have. If the specific thing that works on you is an unusual one, Alarmy probably ships it. It also has a free tier, which is the cheapest way to find out whether a mission alarm works on you at all.
The catchIt leans loud and gamified, which is exactly right for some people and unbearable at 6am for others.

Best for people who dismiss alarms in their sleep
If you have woken up to a phone with the alarm already off and no memory of touching it, the fix might not be software. A cheap clock on the far side of the room puts you on your feet before anything stops, and it does not care whether your phone charged overnight. Nothing you install beats standing up.
The catchIt costs money, it tells you nothing about the night you just had, and if you are the sort who walks back to bed, it only buys you ten seconds.
The iPhone Clock app
Best free way to rule things out
Before paying for anything, put the phone across the room and stack three Clock alarms four minutes apart. It's free, already installed and about as reliable as software gets. If you sleep through all three, you have learned the useful thing: volume is not your problem, and no louder app is going to fix it.
The catchIt cannot ask you to do anything before it stops, so a half-asleep thumb ends it without waking the rest of you.

Best if you wake up but cannot function
Plenty of people called heavy sleepers do wake up. They wake up wrecked, decide the day can wait, and go back under. That is a different problem, and a wake window aimed at a lighter moment is the treatment for it rather than a harder alarm. Sleep Cycle has been doing wake windows longer than almost anyone.
The catchIt will not make you get out of bed. If you dismiss alarms without remembering, a gentler alarm is the wrong direction.

Loud stopped working on you a long time ago
You get used to a sound. That is the whole reason the volume race is a dead end: whatever tone you picked was startling for about a week, and then your brain filed it under things that happen and stopped acting on it. Making it louder buys you another few days of the same.
A dismissal task changes what has to happen before the noise ends. You cannot solve eight digits or walk twenty steps while still asleep, so the alarm stops when you are awake rather than when your hand finds the screen. That is the mechanism worth paying for, and it is the only thing that separates the apps on this page from the one already on your phone.
Two failure modes that get treated as one
Read the reviews on any alarm app and you will find two completely different people writing them, both calling themselves heavy sleepers.
- You never hear it. The alarm rang for nine minutes and you have no memory of it. You want a task, and you want the phone out of reach.
- You hear it and lose the argument. You are awake enough to reason your way into another ten minutes. You want a wake window so you are not being pulled out of the deepest part of the night, plus something that makes stopping it a chore.
Pick for the one that is actually you. The wrong fix here feels like the app failed, when it was aimed at somebody else the whole time.
Seven days that tell you which app to buy
Do this before you spend anything. It costs a week and it usually settles the question.
- Move the charger to the other side of the room tonight. Half the people reading this stop here.
- Keep the same wake time for seven days, weekend included. A moving target makes every alarm harder than it needs to be.
- Stack three Clock alarms, four minutes apart, and write down in the morning which one you remember.
- If you remember none of them, you need a task alarm. If you remember all three and stayed in bed anyway, you need a wake window and a reason to stand up.
Questions people ask
Do alarm apps still ring when the iPhone is on silent?
Only if they are built on AlarmKit, Apple's alarm framework. That is what lets Tock and the built-in Clock app ring through the mute switch, through a Focus and with the app closed. An app that plays audio in the background instead is at the mercy of the silent switch, so check this before you rely on anything.
What actually wakes a heavy sleeper, if not volume?
Something you have to finish. A task that needs your attention, like maths or a phrase or a walk of a few steps, cannot be completed while you are still under. The noise stopping becomes evidence that you woke up rather than evidence that your hand moved.
Is a separate alarm clock better than an app?
For one specific person, yes: the one who turns alarms off in their sleep and does not remember it. A clock across the room forces you upright and does not depend on your phone having charged. It just cannot tell you anything about the night, and most people find they stop using it within a month.
Does Tock have a free version?
No. Tock asks for a subscription after onboarding with a 3-day trial, and it starts from $39.99 a year. If you want to test whether a mission alarm works on you without paying, Alarmy's free tier is the cheaper experiment.
Other roundups
Same treatment, different question.
- The best alarm clock apps for iPhoneFor most iPhone owners the best alarm clock app is the one already installed. The Clock app is free, reliable and enough. Tock is the upgrade worth paying for once the Clock app stops working, which usually means you dismiss it without remembering or you wake up feeling wrecked every morning.
- The best smart alarm apps, and what smart should meanTock is the best smart alarm app on iPhone. It watches the 30 minutes before your alarm using two signals, movement and sound, rings early if it catches a lighter moment, and falls back to your set time no matter what. Sleep Cycle is the long-established alternative, and Pillow is the better pick if you already wear an Apple Watch to bed.
- The best free alarm apps for iPhoneThe best free alarm app for iPhone is the Clock app that came with it. It is free forever, it rings through silent mode and a Focus, and it has never failed. Alarmy is the best free option if you need an alarm that is hard to turn off. Tock is not free and is listed last for that reason.
- The best alarm apps for shift workersFor shift workers the most reliable alarm is still the iPhone Clock app, because it makes no assumptions about your schedule and lets you keep a saved alarm for every shift pattern. Tock is the better pick if you also sleep in the daytime and need something that will not let you turn it off half asleep at 4pm.

- BedtimesGoing to bed at 1:00amWhere to put the alarm after a 1:00am lights-out.
- Sleep by ageHow much sleep adults needThe American Academy of Sleep Medicine recommends that adults sleep 7 or more hours per night on a regular basis to promote optimal health. It is expressed as a minimum rather than a range because the evidence supports a lower bound far more firmly than it supports an ideal figure.
- NapsThe 60 minute napA 60 minute nap includes a substantial amount of slow wave sleep, which is useful for recovery and for some kinds of memory, and it usually ends before the cycle completes. That means the benefit is real and the wake-up is often groggy, so it suits situations where the hour afterwards is flexible.
- Wake tonesKalimbaKalimba is Tock's thumb-piano wake tone: warm plucked notes with a short woody decay that lift you rather than startle you. It still runs on Apple's AlarmKit, so a silent switch, an active Focus and a closed app make no difference to whether it goes off.
- Head to headApple Health Sleep vs RiseApple is the better record and Rise is the better plan. If you keep opening your stage chart and still don't know what to change, Rise is the one built to answer that.
- FeaturesStreaksTock counts a night toward your streak at 90% of your sleep goal, and it bridges one missed night per week automatically. Milestones sit at 3, 7, 14, 30, 60, 100, 180 and 365 nights, drawn as a moon rather than a flame.
Every pick on this page has a catch listed, including ours
Tock is iPhone only, has no free tier and no Apple Watch app. What it does have is an alarm that rings on silent and waits for a lighter moment.
