Alarmy is very good at one job. It is not built for a quiet wake-up.
Alarmy โ made by Delightroom, still known to a lot of people by its old name Sleep If U Can โ is the app most people land on when they search "alarm for heavy sleepers". It deserves that position. It solves a real problem properly: the alarm you switch off in your sleep without remembering it.
This isn't an attempt to knock it. It's an attempt to answer one narrow question honestly: if your problem is that your alarm wakes someone else, or that you can't hear one at all, does Alarmy help?
Short answer, based on everything Delightroom publishes: no, and it doesn't claim to.
Disclosure: we make a wrist-worn vibrating alarm. Read the rest with that in mind.
How we checked
We read Alarmy's own English site, its US App Store listing and its Google Play listing directly on 11 August 2026, and searched the full text of each for vibrate, vibration, silent, haptic, deaf and hearing. Store metrics move daily โ treat every number below as a snapshot of that date.
The numbers: Alarmy's own site gives three different ones
This is the part worth slowing down on. On a single page โ the English homepage โ Alarmy displays three separate audience figures:
| Figure | Exact wording | Where it sits |
|---|---|---|
| 100 million+ | "100M+ Global Users" | Hero, top of page |
| 110 million | "110,000,000 App downloads" | Stats strip |
| 75 million | "Trusted by more than 75 million heavy sleepers worldwide" | Heading above the testimonials |
All three confirmed word-for-word across two independent reads on 11 August 2026. The page also displays "4.8/5 Store Rating". The Korean homepage carries the same download claim in Korean units โ "1.1์ต ๊ฑด", i.e. 110 million.
Are those three numbers a contradiction?
Not necessarily, and we should say so. Downloads, users and "heavy sleepers" are three different things. One person can download an app on a phone and a tablet. A ten-year-old app accumulates downloads it no longer has users for. And "heavy sleepers" reads like a subset by intent, not a headcount.
The charitable reading: 110 million cumulative downloads, of which roughly 100 million are counted as users, of whom 75 million are the heavy sleepers the marketing speaks to.
The less charitable reading is that three numbers on one screen, none defined, none dated, none sourced, is what loose marketing looks like. We'd apply the same test to ourselves: a number you can't state the definition and date of isn't really a number.
What the stores actually show
| Store | Figure |
|---|---|
| Google Play | 4.6 stars |
| Google Play | roughly 2.1 million reviews |
| Google Play | 10M+ downloads |
| Google Play | "Contains ads" |
| US App Store | 4.8 out of 5 |
| US App Store | 242K ratings |
All checked 11 August 2026. Review counts drift daily, so we've rounded rather than pretending to a precision we don't have.
Two things to flag honestly.
First, Google Play's install bucket reads 10M+ while the site claims 110,000,000 downloads. That gap isn't automatically dishonest: Play's counter is Android-only and Alarmy is a large iOS app, Play's buckets are coarse, and the site's figure is cumulative across a decade and multiple platforms. But if you're deciding what to trust, the Play number is the one a third party publishes and the site number is the one Delightroom publishes.
Second, the 4.6 and 4.8 are real and they're high. Two million reviews at 4.6 is not an accident. Whatever follows, Alarmy is a well-liked app.
The missions: what Alarmy actually makes you do
"Missions" are the core idea. The alarm doesn't stop until you complete a task designed to be hard enough that you can't do it half-asleep.
From the App Store listing on 11 August 2026, the missions named are Math, Shake, Photo, QR/Barcode, Memory Game, Wake Up Check, Typing, Step and Squat, and you can combine two to five on a single alarm.
- Photo / QR-Barcode โ you register a photo of somewhere in your home (the bathroom sink is the classic) or stick a QR code on the kettle. The alarm stops when you go there and scan it. This is the strongest mission, because it moves your body out of the bed.
- Math โ problems, with difficulty and quantity you set.
- Shake / Squat / Step โ physical repetition until a counter fills.
- Typing / Memory โ retype a phrase, or repeat a pattern.
- Wake Up Check โ a follow-up some minutes later to catch you going back to sleep.
The Play description leans hard on loudness too, naming sounds including "End of the World" and pitching itself as a loud alarm clock app for heavy sleepers.
That's the design philosophy in one sentence: escalate difficulty and escalate volume until the sleeper loses. For the problem it targets, it works.
Does Alarmy have a vibration-only or silent mode?
We looked properly. Searching the full text of the US App Store listing, the Google Play listing and the English homepage for vibrat, silent, haptic, deaf and hearing returned no matches on any of the three sources, on 11 August 2026.
There is no documented vibration-only mode, no silent mode, and no accessibility claim for deaf or hard-of-hearing users anywhere Delightroom publishes.
Two honest caveats. We didn't install the app, and many alarm apps carry an in-app vibrate toggle that accompanies the sound without ever appearing in store copy โ Alarmy may well have one. What we can say confidently is narrower and more useful: no vibration-only wake-up is documented in any first-party source. And absence from a listing is evidence of priority, not proof of absence. But when a company writes hundreds of words of feature copy across three properties and the word "vibration" never appears once, that tells you what the product is for.
And it's consistent. Alarmy is a loud alarm with hard puzzles. A silent mode would undercut the entire proposition. You can't fault a product for not being a different product.
What Alarmy costs
Here's a finding in its own right: Alarmy does not publish a subscription price on its own website. The English site has no pricing page and no price anywhere on it. It refers to "a Premium version" and stops there. Google Play showed "Contains ads" with no in-app purchase price range published.
The US App Store listing does publish prices. On 11 August 2026 it listed ten in-app purchases ranging from $4.99 to $69.99, under names including Alarmy Premium Basic, Premium Light, Premium Standard, Premium Plus and Alarmy Pro. There's a 7-day free trial.
Read that carefully, because it's less informative than it looks. Apple lists product names and prices but not billing periods. We can't tell you which are monthly, which yearly and which one-off, and we're not going to guess.
