How a cleaning app not updated in 28 days climbed to #1 on Canada's utilities chart

Hyper Cleaner is an Android phone cleaner, listed in Oct 9. By Nov 6 it had nearly 980k installs, and its version number never changed from 1.0.0. It has no new features and nobody talks about it. It got where it is by working the Android cleaning business that has run for over a decade: list under a fresh package name, spend on paid acquisition to push it onto various countries' utilities charts, then earn the money back through ads. This piece covers how it works, how the same developer rotates packages, how crowded this lane is, and what indie devs should take from it and what they should avoid.

A "please clean this for me" review

In Oct 31, a Canadian user gave Hyper Cleaner 3 stars on Google Play. The review said:

am not enjoying it it tells me to clear virus I don't know how to clean please clean for me thanks (Not enjoying it. It tells me to clear a virus, I don't know how to clean it, please clean it for me, thanks)

That same day, Hyper Cleaner ranked #1 on Canada's Google Play free chart for utilities. The next day it was still #1, and its best overall chart position was #22 (Google Play charts, 10-31, 11-01).

This one review pretty much tells the whole story: users are pulled in by "your phone has a virus"-style prompts, don't understand phones well, and can't tell which pop-ups are real. Another Canadian user wrote in Oct 22: "Too many pop-ups, I can't tell which are real and which are fake. It keeps telling me to buy TotalAV to remove viruses, but I bought it months ago." Also in Oct 24: "It works, but it's too rushed for an old guy like me."

What it is

A fairly ordinary storage cleaner: it scans caches and leftover files, finds large files, and manages installed apps. It's free, has no in-app purchases, and the store page is labeled "contains ads".

The store description is restrained: "see how much storage you're using" and "delete what you don't want, at your own pace". It never mentions "boost", "antivirus", or "phone infected". The inference is that this is to pass Google Play's review policies. The alarming messaging lives in ad creatives and in-app pop-ups, not on the store page.

The developer is JTR Labs, with a Gmail address as its listed contact. Its privacy policy is hosted on Google Sites, under a URL containing "turbo-cleanerer", which looks like it was left over from an earlier package (Google Play store page, 11-06). Don't confuse it with another indie software studio also called JTR Labs, which uses a different domain.

28 days, 980k installs

(Google Play install count, 11-06. Play's install numbers update only every few days, so don't read them by single day.)

About 810k new installs in the last 7 days. 11-06 It's charting in 20 countries at the same time: #4 on Canada's utilities chart, #20 in Indonesia and Turkey, #21 in Germany, #22 in Taiwan, and #40 in the US. It has also made the top 10 on utilities charts in Germany, Taiwan, Mexico, Turkey, and Argentina.

Two numbers show these users didn't find it by searching:

• The rating count is only 0.13% of installs (1,263 / 977k). Organically downloaded utility apps usually have a much higher ratio (estimate). Most people who leave reviews only write "good", "nice", or "5 s".
• No discussion anywhere online. In the past 30 days, a search for "Hyper Cleaner" on X returned 0 posts. Web search only turns up the store page and a few chart aggregator sites.

Also, since 11-04 its rankings have been sliding across most countries: 11-06 Germany's overall chart #153, France #160. The push phase has probably already passed.

One developer, package after package

JTR Labs has 4 apps on Google Play:

(Google Play developer page and install counts, 11-06)

The three cleaner apps have nearly identical features and share one privacy policy and one email. Look at Smart Clean Pro's curve: 10-29 it was 480k, then 11-02 it rose to 1.06M, and over the next four days it added only about 90k. Hyper Cleaner picked up right from there, and 11-03 it jumped to 410k in one go.

This is rotating packages: once the old package has run its push, its rating starts to slide (Smart Clean Pro has already dropped to 3.8), and the ad budget moves to the new one. A new package has a clean rating, fresh creatives can be rolled out, and it's easier to get seen on new-app and category charts.

The remaining app, Aether Pass, isn't a cleaner. It's a casual game about flying a glider between glowing gates, with only 500 installs (Google Play store page, 11-06). A cleaner-earning account keeping a small game like this around is commonly explained as a new developer account warming up with a harmless app to get through the review period (inference).

Where the money comes from

It's ads only. Opening the app shows an app-open ad, finishing a scan shows an interstitial, and the results page has more ads. On top of that, the app promotes antivirus software (the TotalAV review above).

The review pool makes the user profile clear: older, not very tech-savvy, and anxious when they see the word "virus". One German user wrote in Oct 21: "Very satisfied, thank you for your help 🙏💝 Your Dieter Müller", signed like a letter. Another German user complained: "Always the same annoying prompt, if it doesn't stop I'm switching phones." These users see a lot of ads and tap by mistake often, which is why the model can work in countries like Canada and Germany where ad buys aren't cheap (inference).

As for exactly where the traffic was bought, whether through Google app campaigns, ad-network interstitials and rewarded videos, or the "your phone is infected" pop-ups on web pages, there's no direct public evidence. The developer isn't in Meta, Google, or TikTok's public ad libraries, but apps like this mostly run on Google's own platform and ad networks, so not showing up there doesn't mean it isn't advertising. No public figures exist for the cost per install or how much ad revenue each user brings back.

Who it's competing with: twenty-plus identical ones

How crowded the lane is: 11-06 on Google Play, there are over twenty cleaner apps with clean / junk / storage / booster in their names, each adding 250k+ new installs in 7 days. Here are a few for comparison:

(Google Play installs and charts, 11-06)

No one is copying anyone. Everyone uses the same template, and the only differences are how much budget goes in and how often the packages get pushed. Even the name "Hyper Cleaner" isn't new: there was already an iOS cleaning app with the same name, from a different company, which PhoneArena listed in 2023 among "84 scam apps".

Why it took off

1. The demand has always been there. The anxiety of "my phone is slow, storage is full, is it infected?" never goes away, and scary creatives get high click-through rates.
2. The tools category charts have a low bar. A few days of paid traffic can push an app into the top 5 of the Canada and Germany Tools charts, and once it's charted, some organic downloads come along for free.
3. Rotating packages. New packages dodge the bad reviews and creative fatigue of old ones. Smart Clean Pro tapered off, and Hyper Cleaner took over.
4. The product costs almost nothing. It hasn't been updated since launch, the description is a generic template, and all the money goes into paid acquisition.

Product quality has nothing to do with it.

If it were you

In short: this is an arbitrage business built on paid acquisition, not a product opportunity. You can learn how to climb Android tools charts from it, but don't build the twentieth cleaner clone.

Who it fits: teams already running paid acquisition on Android, with ad network monetization experience, several developer accounts, and the ability to absorb account bans. For them it's just another category, and they don't need this article.

Who it doesn't fit: indie devs who haven't run paid campaigns; anyone hoping to get traffic from store search, word of mouth, or content (nobody searches for this category or shares these apps); anyone who cares about their accounts and reputation. Scare-tactic pop-ups and antivirus-themed ads are exactly what Google Play keeps checking for, and the handful of accounts used for rotating packages could all get banned at once.

What you can borrow:

• Test new packages on the Tools charts of small countries. The free Tools charts in Canada, Germany, Taiwan, and Mexico have low barriers. A few hundred thousand installs can get you into the top 5. If you build any Android tool, you can validate a paid acquisition model on one or two of these charts with a small budget before deciding whether to scale.
• One feature, many packages. When an old package's rating drops and its creatives tire out, launch a new package and start over, instead of trying to rescue the old one. This also works for legitimate products, as long as every package passes review.
• Keep the store page compliant, put the emotion in the creatives. This is why it survives, and also where this path most easily blows up.

If you really want to enter cleaning: don't copy Hyper Cleaner, look at Codeway's Cleanup. Same category, but it's subscription-based, and it reached #1 on the UAE Tools Top Grossing chart. That path requires a product people actually use, a solid paywall, and sustained spending. That's a different game from seeing who can make the scarier pop-up.

Signs you're reading this wrong: (1) If this kind of ad-only cleaner package keeps flowing into the top 5 of the Canada and Germany Tools charts over the next month or two, and people publicly share numbers showing it pays back, then the arbitrage is still open to newcomers. (2) Conversely, if Google Play takes down large numbers of these apps before year-end, or several JTR Labs packages vanish at the same time, the path is closing.
