1.1M people watched the video, 7 people rated it: Hisaab's Friday alarm won on one line of copy, lost after launch

Hisaab Salah Alarm is a prayer alarm from a small UK company. It rings nonstop at prayer time and only stops when you photograph your prayer mat. This July, before launch, several TikToks passed a million views, and the official account said the waitlist had collected 15k people. It launched in Oct 11, and by Nov 6 App Store ratings across all storefronts totaled just 7. The idea hit a real nerve, but the category already has players. What's worth studying is the three months of TikTok work before launch.

One line watched 1.1M times

In 2026 Jul 19, the TikTok account @hisaabalarm posted a video of the founder talking to camera. It opened with:

The problem was never waking up. The alarm did that. The problem was how easy it was to turn it off and go back to sleep.

(The problem was never waking up, the alarm does that. The problem is how easy it is to hit snooze and go back to sleep.)

The follow-up line is "So I built one that doesn't give up until you get up and pray" (so I built an alarm that won't stop ringing until you get up and pray). Same voiceover, posted several versions the same day: one hit 1.11M views, another 534k. Two days later, a new opener and another post: 504k. Jul 24 video, "The salah alarm you can't switch off": 1.04M views, 93k likes (TikTok @hisaabalarm, as seen 11-06).

It hit a guilt many Muslims know well: the Fajr (pre-dawn prayer) alarm goes off, you hit snooze for "five more minutes", and you wake up to daylight.

Over those weeks the waitlist figures in the videos kept climbing: 7-21 "1,000 people a day", 7-24 "2,000 and counting", 7-25 "3,000+", 7-27 "5,000". In Oct 19 it said: "Before launch, 15,000 Muslims joined the waitlist." All of these are numbers it reported itself.

What it is and how it charges

It rings through all five daily prayers and keeps going until you respond. The response takes three steps: are you ready? → have you done wudu (ablution)? → photograph your prayer mat. The official site says Gemini Vision checks the photo, so a random button tap won't get past it. It also has a few extras: Mosque Mode (reminds you to leave for congregational prayer at mosque times), a daily emergency exit, a menstruation mode, Hanafi and standard Asr calculation methods, and a prayer log that marks missed prayers in red rather than hiding them.

Its positioning is deliberately blunt. The official line is "This app is not for everyone", aimed at people who have tried everything and still can't get up for Fajr.

• Developer: Al-Asturlabi Limited, registered in the UK in 2026 Apr 27, with this as its only app (UK company register, Companies House).
• Price: free to download. Subscription is £4.99 a month or £39.99 a year (UK App Store, 11-06).
• Minimum iOS requirement is 26. This is likely to use the AlarmKit Apple opened up in iOS 26: it lets third-party apps build alarms that still ring on silent or in Focus mode. The tradeoff is that people on iOS 25 and older can't install it.
• Android: still just a waitlist.

15k in line, 7 people rated it

"Charted in a dozen countries" sounds impressive, but it's really Kenya, Niger, Israel, Pakistan and Egypt in the Reference category. Almost no one competes in that category in those places, so a handful of subscriptions can crack the Top Grossing top ten. Going by 7 ratings, total downloads are probably at most a few thousand.

The 5 reviews on the UK storefront are very specific. One says: "I used to use Alarmy, and as a Muslim this changed everything... I gained 3 and 4 extra hours every day, and Fajr went from the hardest prayer to my strongest." Another: "You have to get up and scan your prayer mat. Such a simple idea, but it really works." All the reviews were left between Oct 12 and 15, during the first four days after launch. Almost nothing new has come in since.

After launch it raised posting to 4 to 7 posts a day: product demos, hadith explainers, "The universe is 13.8B years old, and you were nothing", all ending on "Have you prayed your salah yet?". The top post in Oct 18 reached 194k views, and most later posts got a few hundred to three thousand. The Nov 4 post "I tried every way to stop this alarm" got 909 views.

Why the waitlist didn't turn into downloads

A million views in July, single-digit ratings by October: what happened to the people in between isn't visible from outside. Several plausible reasons (all inferred):

• A two-and-a-half-month gap. From August to early October the account was mostly silent, and the July wave had cooled off by October.
• The iOS 26 barrier. Many people on the waitlist probably haven't upgraded their phones.
• A large share of Android users. The official site lists the Android waitlist separately, and those people still have nothing to install.
• The pound-denominated price. £4.99 a month is expensive for users in Arabic-speaking countries and South Asia.
• Watching a video and thinking "that's so true" is not the same as installing an alarm that manages you every day.

There's one more signal: people are already searching "Hisaab alarm app review" on TikTok search, along with the Arabic "Hisaab alarm app صورته" (what it looks like), which lines up with its sporadic chart appearances in Egypt, Algeria, Kuwait and Yemen. There's some organic curiosity in the Arabic-speaking world, but not enough to carry volume.

Who it's competing with

The idea isn't new. Muslim users have long used Alarmy's "scan a bathroom photo to dismiss" feature to get up for Fajr, and people were discussing it on Reddit's r/islam 2019 years ago. From 2025 to 2026, a wave of new apps appeared in this space, falling into two camps: alarms you can't turn off, and phones that lock until you've prayed.

What Hisaab adds is "all five prayers", Mosque Mode, and a sharper positioning. These are small steps forward on the same idea. The copy is what drove it, not these features.

What's worth learning is the three months

The product didn't break out, but July's playbook is worth copying, and it costs almost nothing:

1. Push one pain point, and say it in one line ("The problem isn't waking up, it's how easy it is to dismiss").
2. Founder first-person: "I built a...", not the brand talking.
3. Same script, several versions posted the same day, so the platform picks the one that takes off.
4. Show the waitlist count in videos: 1,000 → 5,000 → 15,000. Each count becomes material for the next video and creates a bandwagon effect.
5. When commenters ask "what's it called", make a dedicated video answering (the 7-22 video got 26k views).

The downside is just as clear: the hype peaked before the product was ready, and by the time it was ready the hype was gone. Launching on iOS first also shut out a large share of Android users in the community.

If it were you

C: Worth learning from, but not worth chasing. The "alarm you can't turn off for prayer" slot is already taken by Just Pray, which launched a year earlier and has two thousand times Hisaab's ratings. Similar apps keep appearing at a rate of one a month, and Hisaab hasn't shown the idea can turn its waitlist into paying users.

• Good fit for: people building an app for a community with a strong "I should, but can't" guilt, using Hisaab's TikTok cold start as a template. Or people who understand a faith or language community nobody has seriously served yet, such as local Arabic, Urdu, Indonesian, or Turkish versions of a Fajr alarm, with local pricing and Android first.
• Not a fit for: anyone planning another "take a photo of your prayer mat to turn it off" alarm for the English-speaking Muslim market. That space is crowded, and there's no product moat.
• How to do it: don't copy the features, copy the rhythm. Test demand on TikTok with one pain-point script and a waitlist page. Once the list passes a few thousand people, ship within 6 to 8 weeks, on Android and iOS together, and don't wait for the newest OS version. Price by local income, not by copying the pound price.
• How to get users: founder talking-head videos, several versions of the same script posted back to back, waitlist counts shown on camera, and comments turned into the next video. After launch, keep making July-style videos that push the pain point, not generic explainers.
• When to start: the biggest moment of the year for Muslim apps is Ramadan, which in 2027 starts in early February. To make it, start testing scripts on TikTok before December and launch by mid-January.
• Signs you've misread this: ① Hisaab's Android version launches and within a few weeks reaches several hundred ratings and charts in the UK or US. That would mean the 15k waitlist was real and only held back by iOS 26 and Android, so demand for this idea is bigger than it looks. ② Ratings for Just Pray or SalahScreen stop growing around Ramadan. That would mean this category is a passing fad, not worth pursuing even in a new market.
