How a "phone cleaner" shell cracked the top 50 of the tools charts in the Netherlands, France, and Germany
What it is A free, ad-supported Android phone cleaner: it scans caches, finds duplicate photos, and lists the largest files.
Why it took off Most likely it's a wave of paid installs. The store title was changed to German and French search terms, pushing it into the top 50 of the tools Top Free charts in the Netherlands, France, Germany, and Spain, then ads recover the spend.
DHow you could follow it Don't build another cleaner. Learn two moves: go after countries where tool-chart entry is cheap and ad CPMs are high, and write the store title in the exact words locals search, in a tool category that hasn't been drowned by reskins yet.
- Data (updated daily) · first launch 2026-07-17 · 11-06 installs 489,766
Android · Total installs worldwide Data 2026-10-29 → 2026-11-06 (9 days, 9 observations). Google's detail page only refreshes install counts every other day, so a flat day doesn't mean nobody installed.
Google Play has a phone cleaner called "Clean My Files" that launched in mid-July and reached about 490k installs by November 6, with another 67k added in the last week. Its features are identical to Files by Google, and nobody online is talking about it. It got there with money: a series of paid installs, store titles rewritten in German and French to match what locals search, and a push for the charts in a few Western European countries where the bar is low and ads pay well, with ads recovering the spend. Below is how the play works, and why it's not worth copying: over half a year, more than a hundred similar cleaner apps appeared.
One review: "I didn't install it on purpose"
In 2026 Sep 29, a user in South Africa named Elizma Morkel left a review on its store page: "I never meant to install this app, and it added two apps to my lock screen that I can't uninstall." 9 people marked it helpful. Two weeks ago, someone in Nigeria wrote: "The pop-ups and random apps are so annoying." In Oct 16, a review from the French store was a single line: "Such a stubborn thing, I can't get rid of it."
On the German store page, though, the top reviews have a different tone: "So far very satisfied, easy to use" (30,33 people marked it helpful, Aug) and "Good, clean, fast." The French review "Good, nothing to complain about, thanks" got 42 helpful votes.
Put these reviews together and you get a rough picture of where its users come from. Some were pulled in by ads or pop-ups and didn't know what they installed. Others are ordinary people in Western Europe who genuinely wanted to clean up their phones, and judging by their tone, many are older (inferred).
What it is
A free, ad-supported storage cleaner with no in-app purchases. It does three things: scans caches, empty folders, and old downloads; groups duplicate and blurry photos; and lists the largest files by size. Its store description sells the point that "our tool never makes decisions for you automatically" and "100% offline, no uploads," distinguishing it from the flashy "one-tap boost" cleaner apps.
All of these features are in Files by Google: free, no ads, and preinstalled on lots of Android phones. The app has no functional edge.
One detail: the APK is about 90MB. A file-cleaner that size is abnormal and probably bundles a lot of ad SDKs (inferred). Versions went from 1.1 (early September) to 1.5 (late October).
The numbers: the curve moves in steps
- Cumulative installs 489,766, +7 over the last 66,736 days, about 9,500 per day on average (Google Play public data plus third-party estimates, 11-06). The store page only shows the bracket "100k+".
- Aug 11 total was only 3,926. From Sep 1 to 3, it grew about 57k over three days, Sep 10 alone added +39k, Oct 4 added +34k, and Oct 8 added +24k; in between, days like Oct 2, 7, 16 and 28 only added a few dozen.
- Same story the past week: 10-31 +11.7k, 11-01 and 11-02 both at 0,11-03 +36k, and 11-04 back at 0.
Installs from word of mouth and search grow smoothly. This curve starts and stops, which matches the shape of ad budgets being switched on and off. I don't have its ad creatives, so paid acquisition is inferred, with medium-to-high confidence.
Review counts don't match installs either: every storefront shows about 1,120 reviews, only 0.23% of installs. Ratings range from 4.1 in Nigeria to 4.8 in the Netherlands. Whether reviews are faked is unverified.
Why it charts: pick the country, rewrite the title
It hasn't charted in the US or UK. In Nov 6 it was on these tool free charts:
| Country | Free Utilities chart rank (11-06) |
|---|---|
| Netherlands | 29 |
| France | 32 |
| Germany | 33 |
| Spain | 49 |
| Hong Kong | 62 |
It also reached the overall app charts in France (162) and the Netherlands (174). A week earlier (10-29) it was outside the top 100 of the utility charts in only France, Hong Kong and Thailand.
Two things work together.
First, pick the countries. A single user is worth more in the Netherlands, France and Germany, and the utility charts have a low bar. A few thousand to ten thousand global installs a day, spread across these countries, is enough for a top-50 spot. Charting then brings a bit of organic traffic on its own.
Second, rewrite the title in the words locals search. The German listing is "Meine Dateien bereinigen" (clean my files), the French one is "Nettoyer Mes Fichiers", and the Dutch and English listings are "Clean My Files". The descriptions are fully translated into German and French too. This isn't a literal translation of the app name. It's the phrase a user would type into the store.
Who's behind it: the names don't match
The store lists the developer as "Jhundoo Lal". The support email is a gmail called timevaultsuccess, the website is ter.suntessw.com, and the phone number starts with +92, a Pakistani number. But the developer info at the bottom of the page lists the company as FastFinTech LLC, at 1309 Coffeen Ave in Sheridan, Wyoming, an address shared by many registered-agent companies. FastFinTech's own website sells options data and has nothing to do with cleaning apps.
A name, a phone number and a company that all disagree fits the pattern of utility app studios borrowing or buying developer accounts and publishing in batches (inferred). This account previously published "MSM - Mini Shop Manager", which Play removed in May 15. It now also has a "FileRecovery" app.
Where the money comes from
Ads only. The store page is labeled "Contains ads", with no in-app purchases and no subscriptions. From the reviews, the ads aren't just app-open and interstitial. Lock-screen and pop-up ads are likely too.
The math on a cleaner: you pay for one install, the user opens the app a few times and sees a few ads, and if ad revenue beats acquisition cost, you keep buying. Ad rates in Western Europe are high, so it puts its effort into France, Germany, the Netherlands and Spain (rates and revenue aren't public; these are estimates).
Who it's competing with
| Competitors | Scale (Google Play) | Compared with alternatives |
|---|---|---|
| Files by Google | Billions of installs, often preinstalled | Free, no ads, same features |
| CCleaner / Avast Cleanup | 160M / 95M | Veteran, earns from subscriptions |
| CleanX(TapSuite) | 4M, 7 days +510k | Same wave of new clones, an order of magnitude bigger, #6 on the Dutch utilities chart |
| Hyper Cleaner / Smart Clean Pro(JTR Labs) | 980k / 1.15M, 7 days +810k / +670k | Launched only one or two months ago, growing ten times faster |
| CleanMax, EasyClean, NovaClean, SwiClean and others | 1M–6M each | Nearly identical names and features, developer names all over the place |
I counted every utility app launched less than 200 days ago whose title includes clean, junk or storage: 146 in total, about 112M installs combined, and up 13.2M over the last 7 days. 55 of them grew faster than it did in the past week. It's mid-table in this group.
How many people know about it
Almost nothing. No press coverage, no discussion on X, no related TikTok videos, no public revenue. Online there are only auto-generated pages from APKPure and AppBrain. That doesn't mean there's an opening, though: plenty of people run this playbook, they just don't talk about it.
If it were you
D: understand the playbook, but I wouldn't copy it. It has no product, only a distribution pipeline: usable developer accounts, a reskinned codebase, country selection by chart, titles rewritten for local search, paid acquisition in stages, ads paying back. This pipeline already runs more than a hundred cleaning apps, several of them ten times its size. Getting in takes an acquisition budget and accounts, and you carry the risk yourself.
Who it suits: small studios already building utility clones, with usable developer accounts, that can run Google App Campaigns. The only lesson for you: the same installs are invisible in the US but reach the top 50 of the utility charts in the Netherlands, France and Germany, where ads are worth more.
Who it doesn't suit: indie developers who want their own product and to grow users slowly. The system cleaner and Files by Google are both free, users have no loyalty, and some don't even know they installed this app.
How to do it: don't build another cleaner. Copy two moves. One: open the utility charts by country and look for places with a low bar and high ad rates (small Western European languages are one such group). Two: write the store title as the phrase locals would search, not a translated app name. Pick a category that hasn't been flooded by reskins yet.
How to get users: run Google App Campaigns or ad networks separately by country. Test with a small budget to see which countries are cheapest to chart in, then use the chart to pick up organic installs. Don't copy its lock-screen ads or misleading installs. Those are what produce "can't uninstall" reviews and takedowns.
Risk: Google Play has specific policies for cleaner apps, misleading ads and lock-screen ads, and this developer account has already had an app removed. If the account gets flagged, every app on it goes with it.
What would show I'm wrong: ① it's taken down before year-end, or the new cleaner clones disappear from the Western European utility charts together. That would mean Google has closed the window for this category. ② It keeps adding thousands a day after paid acquisition stops. That would mean charting and localized titles drive more organic installs than I think, and the country-plus-title method is worth more than D. ③ The reverse: cleaner clones launched in early 2027 are still flooding the Western European utility charts in front of 50. That would mean the business still pays, but it's more crowded now.

Why Clean My Files (com.clean.my.fileso.lter) gets charted
Channel: Google Play / Utilities · Developer "Jhundoo Lal" · Research date 2026-11-06
Bottom line
It didn't get here on product. It's an ordinary member of the phone-cleaner reskin wave on Google Play in the second half of 2026: standard cache scanning, duplicate-photo finding and large-file listing, monetized with ads alone, no subscriptions, no in-app purchases. The install curve moves in bursts, the users cluster in older markets in Western Europe, reviews say "I didn't install this myself", "can't uninstall" and "too many pop-ups", and the store page is localized with translated titles. The signs point to paid acquisition (most likely aggressive Google App Campaigns or ad networks) combined with multilingual store optimization (ASO). The installs are bought and the ads pay it back. It isn't standout even within its category: in our library, 146 cleaner apps launched within 200 days, and 55 of them grew faster than it did over the last 7 days.

- Store description: scans cache, empty folders and old downloads, finds duplicate and blurry photos, lists large files by size. Selling points: "we don't delete for you automatically, you decide", "100% offline, no upload". Source: Play store page
- The page is labeled "Contains ads". In our library,
ad_supported=Trueandoffers_iap=False, so it earns from ads only. Source: googleplay library app_snap, 2026-10-29 to 11-06 - Release cadence: 1.1 (2026-09-01), 1.3 (09-29 / store 09-18), 1.5 (11-02 / store 10-29). The APK is 90MB (XAPK). A file-cleaner that size is abnormal and probably bundles many ad SDKs (unverified). Source: APKPure version history
- Store titles are localized by language: German is "Meine Dateien bereinigen", French is "Nettoyer Mes Fichiers", Dutch and English are "Clean My Files". Source: Play store pages hl=de/fr/nl
2. Growth data
- Cumulative global installs 489,766, +7 over the last 66,736 days (about 9.5k/day); the store shows only the bracket "100K+". Source: googleplay library app_profile / app_day, 2026-11-06
- Curve since launch (AppstoreSpy estimate, googleplay library app_day_ext): 2026-08-11 was only 3,926; 09-01 to 09-03 added about 57k over three days; 09-10 alone +39k; 10-04 +34k; 10-08 +24k; in between are days with almost no growth (10-02, 10-07, 10-16, 10-28 each added only a few dozen). A stepped curve like this looks like ad budgets being switched on and off, not organic word of mouth.
- Charts: 2026-11-06 #29 on the Netherlands free utilities chart, #32 in France, #33 in Germany, #49 in Spain, and it also reached the overall app charts in France and the Netherlands (162 / 174). At 10-29 it was only outside the top 100 on the utility charts in France, Hong Kong and Thailand. In the last week it has clearly been climbing the Western European charts.

- Review counts: every storefront shows about 1.12K reviews, only about 0.23% of its 490k installs. Ratings range from 4.1 (Nigeria) to 4.8–4.9 (Netherlands) depending on the storefront.
3. Competitors
| Competitors | Where | Launched | Scale | How it differs |
|---|---|---|---|---|
| Files by Google | Big-company features / Android | 2017 | 8B+ installs (googleplay library) | Free, no ads, preinstalled on many phones, and the cleaning features are the same. Clean My Files has no feature advantage. |
| CCleaner / Avast Cleanup | Android | Around 2014 | 160M / 95M installs | Long-established, with a subscription business. Clean My Files only runs ads and relies on cheap paid acquisition. |
| CleanX(TapSuite) | Android | about 168 days ago | 4M, +7k on day 510, #6 in the Netherlands utilities chart | Same wave of new cleaner apps, one order of magnitude bigger, and it also hit the Top Grossing chart. |
| Hyper Cleaner / Smart Clean Pro(JTR Labs) | Android | 28 / 49 days ago | 980k / 1.15M, 7 +810k / +670k | Same playbook, faster growth |
| CleanMax, EasyClean, NovaClean, SwiClean and others | Android | Last 6 months | 1M–6M each | Almost identical names and features, with a scattering of developer names (a French heritage association, a shipping company's name). It's a batch of accounts used to flood the charts. |
| AntiVirus Clean Master-Cleaner | Android | Not verified | #8 in the Netherlands utilities chart | A cleaner app ranking higher on the same Dutch chart |
Library tally (googleplay library app_profile, titles containing clean / junk / storage, utilities category, listed ≤200 days): 146 apps in total, roughly 112M cumulative installs, 7M combined over the last 13.2 days; 55 of them grew faster than Clean My Files on a daily basis (7 per day). This is a crowded red ocean, and it sits in the middle of the pack.
4. Where users came from (growth tactics)
- Paid acquisition (inferred, ad creatives not retrieved):
- The curve is stair-stepped, jumping between single-day gains of +20k and +40k with flat days in between (AppstoreSpy estimate).
- English reviews from South Africa / Nigeria: "I did not intentionally download this app, I got two other apps downloaded on my Screensaver that I cannot uninstall" (2026-09-29,9 people found it helpful); "Too many disturbance from infrequent pop ups and apps" (09-14). French-market review: "véritable plaie Impossible de virer cette application" (10-16). These suggest some people were misled by ads or tapped into an install, and the app has lock-screen or pop-up style ads.
- Our Meta / TikTok / Google ad libraries don't track it (it's not on the watchlist), so finding nothing doesn't mean it isn't advertising; ad creatives unverified.
- Multilingual store optimization (confirmed): the German and French titles use the words locals actually search for ("Meine Dateien bereinigen", "Nettoyer Mes Fichiers"), alongside rising positions on the utilities charts in four countries: Germany, France, the Netherlands and Spain.
- Organic traffic from store search + charts (partial): once it cracked the top 50 on Western European utilities charts, the chart placement itself brought in some organic installs.
- Creators / influencers / social: none found. A TikTok search for "Clean My Files app" returns no relevant videos (TikHub); X corpus has zero posts (x-radar, 60 days); the web only has auto-generated aggregator pages like AppBrain, APKPure and Similarweb.
- Entity info: the developer shown on Play is "Jhundoo Lal", with website ter.suntessw.com, email [email protected] and phone +92 (Pakistan). But the legal entity named in "About the developer" is FastFinTech LLC, with an address at Sheridan 1309 Coffeen Ave, Wyoming, a common registered-agent address. FastFinTech's website (fastfintech.dev) is about options data and has nothing to do with cleaner apps. A name-and-entity mismatch like this fits the pattern of an app farm that borrows or buys developer accounts to mass-publish utility apps (inferred). This developer's earlier app "MSM - Mini Shop Manager" was removed from Play in 2026-05-15 (AppBrain); the same account also has a FileRecovery app.
5. How the money comes back
No in-app purchases, no subscriptions, only ads: interstitials, app-open ads, and probably lock-screen or pop-up ads (judging from reviews). Cleaner apps tend to work like this: buy installs cheaply, then monetize with high-frequency ads after install, and keep spending as long as the ad revenue per install exceeds the acquisition cost. Western Europe (France, Germany, the Netherlands) has high ad rates and many older users (judging by reviewers' names and wording), which is why it focuses on these countries. Specific CPMs and revenue are unverified.
6. Differentiation
The store copy promises "won't decide for you automatically" and "fully offline, no uploads", which tries to separate it from over-the-top "one-tap boost" cleaners and seem more trustworthy. But its features fully overlap with Files by Google and hundreds of similar apps, and the copy is not what drove the installs. The only real difference is distribution and localization: it picked a few high-CPM Western European utilities charts with relatively little competition to push on. Conclusion: differentiation is not why it took off.
7. How visible it is
- No media coverage, zero discussion on X, no creator content on TikTok, and no public revenue. It only shows up in automated lists like StoRank's "German utilities rising".
- But this category is a packed red ocean, so "nobody knows about it" does not mean there's an opening. It's an ordinary fish in a red ocean.
8. What others can borrow
- Category charts in small countries and minor languages have low entry barriers: #29 on the Dutch utilities chart needs only a few thousand installs a day. When buying installs, you can pick countries where ad rates are high and chart thresholds are low.
- Localize store titles around local search terms, not just translate them.
- Privacy copy like "offline, no uploads, you decide" can be sold as a trust signal in the cleaner category.
- The cautionary side: lock-screen ads and misleading installs bring "can't uninstall" reviews and removal risk; this developer already had an app removed.
9. Uncertain
- Which paid acquisition channels were used (Google App Ads / Meta / ad networks) and what the creatives looked like: neither verified.
- The relationship between FastFinTech LLC and Jhundoo Lal, and whether the developer account was bought: inferred, not confirmed.
- 1.12K reviews, and whether ratings of 4.1–4.9 across regions were inflated with fake positive reviews: not verified.
- Revenue and ad revenue per install: unknown.
