The best alarm apps for heavy sleepers

We make Risly. That is a conflict of interest, so this list says plainly where we lose, and we lose in several places on this page.

What is the best alarm app for heavy sleepers?

In one sentence: Risly if you are late and want a mission you cannot dodge on a real system alarm, Alarmy if you want every feature in one app, Wayk if you want the mission format on a phone Risly will not run on, SuperAlarm if you want a mission alarm that costs nothing and installs on an iPhone stuck below iOS 26, Sleep Cycle if you already get up on time and just feel wrecked, the built-in Clock app with snooze switched off if you have never tried the free fix first, and Alarm Clock Xtreme if you are on Android and want free.

Why doesn’t a louder alarm work for heavy sleepers?

Because you are not failing to hear it. Victoria University spent a decade testing alarm signals on sleeping people and published the summary in Fire Technology: many participants did not wake to the standard high-pitched alarm tone even at 95 dBA at the pillow, roughly a passing motorbike, held against your ear. What woke almost everyone in the same research was not a louder sound but a different one, a low 520 Hz square wave. Level matters less than the shape of the signal, which is why the extra decibels an app promises you buy so little.

What does move is the difficulty of switching it off. In a 2025 analysis of 3,017,276 sleep sessions from 21,222 people (run by Mass General Brigham researchers on Sleep Cycle’s own app data, and published in Scientific Reports), 55.6% of sessions ended in a snooze. When the snooze was used it took 10.8 minutes on average; the heaviest snoozers pressed it 4 times and lost 20.2 minutes every morning. An alarm that is easy to dismiss gets dismissed: reliably, at scale, by people who fully intended to get up.

1. Risly: the alarm with no snooze button

1

Risly

For heavy sleepers who are chronically late: a dismissal task you cannot fake, running on a real system alarm.

iOS 26+·3-day free trial, then $29.99/year

• No snooze button anywhere: not in settings, not behind a long-press
• Built on AlarmKit: rings through silent mode, Focus, and a force-quit
• Seven missions to choose from (object scan, QR, barcode, push-ups, math, memory, shake), and every camera mission runs on-device
• No ads and no upsells inside the app

• Requires iOS 26 or later, and there is no Android version
• No sleep tracking and no sleep sounds
• No permanent free tier

Risly is a mission alarm for iPhone, made by Belle Étoile Labs: us. The alarm rings and there is no button to stop it. There is a mission, and you pick which one from seven. Four of them use the camera: scan the object the app names, from a pool of household things you registered yourself; scan a QR sheet you printed and taped up at the far end of the flat; scan the barcode off something you already own, a cereal box or a shampoo bottle; or do push-ups the front camera counts. Two use the screen: chained math problems, or a pattern that flashes on a grid and has to be tapped back from memory, both with the difficulty set by you. The seventh uses nothing but the phone: shake it thirty times. Every camera mission runs on-device. Finish the mission and the alarm stops. Do not finish it and it keeps ringing.

The part that matters for heavy sleepers specifically: Risly is built on AlarmKit, the iOS 26 framework that lets a third-party app schedule a real system alarm. It rings through silent mode, through Focus, through Do Not Disturb, and it rings if you force-quit the app the night before. That is why its support page does not ask you to reconfigure your phone: there is nothing to reconfigure. Longer version on the anti-snooze page.

Where it loses: iOS 26 or later only, so no Android and no older iPhones. No sleep tracking. No sleep sounds. It is unpleasant on purpose, and if you want to be woken kindly you will hate it.

2. Alarmy: the deepest feature set on the market

2

Alarmy

For Android owners and anyone who wants every mission type, sleep tracking and sleep sounds in one app.

iOS + Android·Free with ads, or subscription

• The widest mission library there is: typing, photo and squats on top of everything else in this comparison
• Sleep tracking, sleep sounds and a wake-up check in one app
• Over a decade of edge cases sanded off, on both platforms

• Ads in the free tier, and the full experience sits behind a subscription
• Asks you to configure the phone around it: silent mode off, Alarmy allow-listed in Do Not Disturb
• Photo and barcode missions can be brute-forced with a screenshot or a printout

Alarmy, from Seoul studio Delightroom, has been shipping for over a decade and the company reports 100 million cumulative downloads and a number-one download ranking in 100 countries. It has more mission types than anyone: photo, barcode, QR, math, memory cards, typing, shake, squats. Most of that list is in Risly as well; the typing, photo and squat missions are not, and nobody else ships as many in one app. It tracks sleep. It has a wake-up check that catches you if you crawl back to bed. On Android it is close to unbeatable.

Where it loses: the free tier carries ads, the app has grown a lot of surface area, and, the real one, it predates AlarmKit, so its own help article on alarms that did not ring asks you to keep silent mode off, never force-quit the app, and allow-list Alarmy inside Do Not Disturb and every Focus. Full breakdown in Alarmy alternatives.

3. Wayk: the same idea as Risly, on far more phones

3

Wayk

For anyone who wants a mission alarm but is stuck below iOS 26, or on Android, where Risly simply does not exist.

iOS 17+ and Android·Free to download; its listing states a Wayk Pro subscription is required to set alarms and use missions

• Runs from iOS 17, so it covers iPhones Risly cannot support at all
• There is an Android build; Risly has none, and that is not a small gap
• Missions we do not have: make your bed, read a Bible verse, read an affirmation out loud
• Push-ups, sky photo and find-an-object missions too, plus streaks and morning insights
• Around 18,200 US ratings at a 4.8 average for an app released in February 2026

• Supporting iOS 17 means the alarm cannot be an AlarmKit system alarm across its user base; AlarmKit does not exist before iOS 26
• On those older phones an alarm is a notification plus background audio, which iOS may mute, delay or kill
• Nothing is free: by its own store description you need an active subscription before you can set a single alarm
• Released in February 2026, so it has had months of contact with real mornings, not years

Wayk, from Dialed Labs, landed on the App Store on 3 February 2026 and got big fast: around 18,200 US ratings at a 4.8 average inside six months, which almost nothing in this category does. The premise is the one you already know from this page: the alarm rings, and it does not stop until you have done something. Its mission list overlaps ours and then goes past it: push-ups, a photo of the sky, finding a random object, but also making your bed, reading a Bible verse and reading an affirmation out loud. It keeps streaks and morning stats, and it ships on both iPhone and Android.

So pick Wayk over Risly in three cases, and they are real ones. Your iPhone cannot run iOS 26? Then Risly is not a product you can buy, and arguing about frameworks is academic. You are on Android? Same conclusion, faster. Or the mission you actually want is one of theirs: we do not make your bed, we do not do scripture, we do not do spoken affirmations, and if that is the ritual that gets you upright then buy the app that has it.

Where it loses: on a phone that runs iOS 26, the delivery layer is the whole argument. Supporting iOS 17 means Wayk has to work on phones where AlarmKit does not exist, so across its installed base the alarm cannot be a system alarm; on those devices it is a notification plus background audio, the same arrangement every alarm app lived with before 2025, and iOS is allowed to mute it, delay it or kill the app. The other thing to know before you download: the free download is not a free tier. Wayk’s own App Store description says an active Wayk Pro subscription is required to set alarms and use missions at all: you subscribe first, then you get an alarm clock.

4. SuperAlarm: free, and it installs where Risly cannot

4

SuperAlarm

For heavy sleepers on an iPhone below iOS 26, and for anyone who wants a scan-based mission alarm without paying to find out whether missions work on them.

iOS 17+·Free to download

• Free to download, where Risly and Wayk both expect a subscription; this is its real edge over us
• Installs from iOS 17, so it reaches iPhones Risly cannot
• Object scanning and barcode scanning, the missions that physically walk you out of the bedroom
• Face ID and a walking mission alongside math and memory, two dismissal types Risly does not have
• A wake-up check that catches you if you go back to bed, like Alarmy’s
• Around 4,384 US ratings at a 4.6 average, and still being updated; version 4.0.1 landed in July 2026

• Supporting iOS 17 means it cannot hand every user an AlarmKit system alarm; that framework starts at iOS 26
• We have not verified an Android build; treat it as an iPhone app until its developer says otherwise
• A barcode mission is only as strong as the barcode: print a spare and the obstacle is gone

SuperAlarm is the work of Jiseop Han, an independent Korean developer publishing under team.pickyz.io. It arrived on the App Store in April 2024, it was last updated in July 2026 at version 4.0.1, and it sits on roughly 4,384 US ratings at a 4.6 average: small next to Alarmy, healthy for a solo build, and the update cadence says someone is still answering for it. The dismissal list is long: math, memory games, barcode scanning, object scanning, Face ID, and a walking mission that holds the alarm until you have covered ground. There is also a wake-up check, the same follow-up trick Alarmy uses, for the specific failure where you complete the mission and then negotiate your way back under the duvet.

On missions the two apps land in almost the same place: object scanning, barcodes, math, memory games all sit in Risly too, and SuperAlarm adds Face ID and walking where we add QR and push-ups. So the feature column is not what should decide this one. Two other things should. SuperAlarm is free and starts at iOS 17; Risly is paid and starts at iOS 26. Which means the honest instruction is the boring one: if your iPhone cannot take iOS 26, or you would rather not pay to find out whether a mission alarm works on you at all, install SuperAlarm first. If it gets your feet on the floor, you have solved the problem and you owe us nothing.

Where it loses: the delivery layer, for the same structural reason as Wayk. An app that supports iOS 17 cannot promise an AlarmKit system alarm to everyone who installs it, because AlarmKit begins at iOS 26; on the older phones the alarm is a scheduled notification with audio behind it, and iOS gets the final say on whether that survives silent mode, a Focus and a night of memory pressure. We have also seen no Android version, so do not plan around one. And the barcode mission carries the weakness every barcode mission carries: a printed copy on the nightstand converts the obstacle back into a swipe.

5. Sleep Cycle: the best app here, for a different problem

5

Sleep Cycle

For people who get up on time but feel destroyed: gentle wake-ups and the best sleep tracking in the category.

iOS + Android·Free tier, or subscription

• Wakes you at the lightest point of a wake-up window you set, up to 30 minutes
• Sleep tracking refined since the app launched in 2009; the data side is excellent
• Kind by design: no missions, no confrontation

• Has a snooze button, on purpose
• Nothing stops you dismissing it and rolling over
• The interesting features sit behind the subscription

Sleep Cycle, from Swedish developer Sleep Cycle AB, wakes you inside a wake-up window you set (anywhere from 10 to 30 minutes) at the lightest point of sleep it can detect, and it has been refining that since the app launched in 2009. If your complaint is "I get up on time but I feel destroyed", this is your app and the mission-based alarms are the wrong purchase. Where it loses for heavy sleepers: it has a snooze button and its philosophy is to be kind to you. A heavy sleeper at 6:40am does not need kindness. They need an obstacle.

6. The iPhone Clock app: try this before you pay anyone

Before you pay for anything above, try this. Open the Clock app, edit your alarm, and turn the Snooze toggle off. It is free, it rings through silent mode and Focus, and for a surprising number of people that single toggle is the whole fix. Its weakness is the obvious one: dismissing it takes one swipe and no thought, which is exactly the action a half-asleep heavy sleeper is best at. If you have already tried it and you are still sleeping through your alarm, that is your signal to move back up this list.

7. Alarm Clock Xtreme: strong on Android, not the same product on iPhone

7

Alarm Clock Xtreme

For Android owners who want a solid free mission alarm. Not really an iPhone option.

Android (the iOS namesakes are other apps)·Free with ads, premium unlock

• Math problems to dismiss, gradual volume ramps, a strong widget
• Genuinely good free tier on Android

• The app people recommend is the Android one; same-name apps on the iOS App Store come from other developers with a fraction of the features
• No AlarmKit, so nothing shields it from silent mode on an iPhone

It comes last here because it is the one entry on the page that is not really an iPhone option at all. Half the listicles on this keyword hand Alarm Clock Xtreme to iPhone users anyway. The app they mean is the Android one, published by AVG Labs. Apps with the same name do exist on the iOS App Store, but they come from different developers and carry a fraction of the features, so on iPhone you are not buying the product the review described. On Android it is a strong free option with math dismissal and a decent widget.

What can no alarm app fix?

Three things, and no app on this page touches any of them: not enough sleep, an untreated medical cause, and an iPhone too old for AlarmKit. Worth saying before you spend money, because a paid app that does not work is worse than no app: it burns the belief that anything can work.

• Not enough sleep. Roughly one in three US adults sleeps under seven hours: 33.2%, age-adjusted, in the 2020 national survey published in Preventing Chronic Disease. A lot of self-described heavy sleepers are simply short of sleep, and no app fixes that. An earlier bedtime does.
• A medical cause. Sleep apnea, narcolepsy, thyroid disorders and depression all present as "I cannot wake up", and none of them responds to a louder phone. If you sleep nine hours and still cannot move, see a doctor before you open the App Store.
• Being on an older iPhone. Risly requires iOS 26 or later, because AlarmKit does not exist before it. On iOS 18 no third-party alarm can promise you a system-grade alarm (SuperAlarm and Wayk included), so keep a Clock app alarm with the snooze toggle off running underneath whichever mission app you install.

And one thing an app can fix that most people never try: the first alarm being a lie. If you set 6:00 and get up at 6:40, you do not have an alarm problem, you have a scheduling fiction. Set it for 6:40 and mean it. Half the people who call themselves heavy sleepers are simply arguing with an alarm they never intended to obey.

Take an illustrative case, not a study: Darnell, 36, opens a parts depot outside Toledo and sets three alarms on a phone that lives face-down on silent. He hears none of them, and by 5:50 all three are switched off with no memory of switching them. Nothing on this page makes him a morning person. One row of the table above does the only job he needs: it rings anyway, and it will not stop for a swipe.

How do you choose, in one paragraph?

If you are late and on iOS 26: Risly or Alarmy. If you are late on an older iPhone: SuperAlarm first, because it is free, then Wayk; Risly will not install either way. If you are on Android: Alarmy, Wayk or Alarm Clock Xtreme. If you are groggy but punctual: Sleep Cycle. If you have never turned off the built-in snooze toggle: do that first, for free, tonight. And whichever you choose, put the phone across the room: every app on this list works better from six feet away. If you would rather buy hardware than software, we ranked the alarms that make you get out of bed (Clocky, Ruggie and the wake-up lights) on the same two questions.

Fair questions
