"Spent a day and a night looking for a cleaner app": how a French cleaner used ad spend to hit #2 on the French tools chart
What it is An Android phone storage cleaner that finds junk files, large files, and similar photos. It's free and makes money from ads inside the app.
Why it took off The publisher rolled out paid acquisition budgets market by market, targeting France, where tools charts are easy to climb and ad CPMs are high, then sold impressions through nearly 30 ad networks. Changing the home screen and pushing notifications squeezed in more ads, and hurt its reputation.
CHow you could approach it Don't build another cleaner. A team with paid acquisition and monetization ability could borrow the publisher's way of picking markets: go after countries where the tools chart is low-barrier and ad CPMs are high, localize, then test many small-budget packages to see what pays back.

Quick Clean Space (listed in France as Nettoyage Rapide de Fichiers) is an Android storage cleaner. It launched in July, and after an October update, daily installs jumped from two or three thousand to forty or fifty thousand. By November it had 6 installs on Google Play... wait, the number is 820K. Its features are no different from Files by Google, the phone's built-in tool. It took off because a publisher that specializes in batch-deploying sock-puppet apps picked it up and spent ad budget on it, and it targeted France: the tools chart there is easy to climb, and ads sell at a premium. Here's what it runs on, where the money comes from, who it competes with, and whether you should follow it.
Two reviews, one story
2026 Oct 5, French user Patrick Hugo left a five-star review on the store page: "I wanted to install a cleaner app and have been struggling for a day and a night... so many other apps kept getting installed along with it, and as a beginner I was going crazy. This one installed in under a minute... finally something that behaves sensibly like it used to. Thank you." By Nov 6, the review had 398 helpful votes and sat at the top of the French store page.
Second place is an Oct 11 one-star review from Michel Richter: "Too bossy. It rearranged my entire home screen without asking. I can't delete the stuff I don't want on the main screen, and I can't put it back the way I want." 204 people marked it helpful.
One is a newbie who was led through a string of ads and finally installed it; the other is a user who found their phone taken over after installing. Quick Clean Space's business sits between these two reviews.
What it is
The store page lists the standard cleaner trio: finding temp files and leftover junk, listing large videos and documents by size, and grouping blurry or near-identical photos, plus a line: "100% local scan, never uploads your files." It's tagged "contains ads," has no in-app purchases, and costs nothing.
But the permissions it asks for go well beyond cleaning. The Exodus privacy report (10-11,1.1 version) counts 31 trackers and 27 permissions, including reading app usage data, managing all storage, requesting to uninstall other apps, reading the calendar, precise location, and the camera. The store's data safety section also says it collects photos, videos, and calendar data, and shares device IDs with third parties.
After the version 1.1 update in early October, a batch of similar complaints showed up in the French reviews: "It changed my whole phone screen" (Anne-Marie Fraty, 10-09), "I installed it by accident and now I can't get rid of it" (Meredith Saillens, 10-11), "Too many ads", and "The ringtone keeps going off, I can't sleep, so I uninstalled it" (10-31). Our guess is the version 1.1 added more ad-display tactics like changing the home screen, floating entry points, and notification nudges. We haven't verified how they were actually implemented.
Volume gets turned on in steps
| Timeline | Total installs | Daily new installs |
|---|---|---|
| Mid August | About 13k | About 2,000 (third-party estimate) |
| 10-03 | About 150k | 2,000–4,000 (third-party estimate) |
| 10-15 | About 400k | 10-12 to 10-15 roughly 4–50k per day (third-party estimate) |
| 10-29 | 530k | — |
| 11-03 | 768k | About 48k |
| 11-06 | 822k | 1.6–22k |
Source: the 8–October figures are AppstoreSpy estimates; from 10-29 on, they're daily scrapes of public install counts on Google Play.
The curve is stepped: 10-04, 10-07 to 10-09, 10-12 to 10-15, and 10-25 to 10-27, 10-30 to 11-03 each got a push, with near-zero days in between (10-05 added only 13, 10-28 added only 48). Organic traffic doesn't look like this. It looks more like budget switched on and off in blocks.
Another number: over the 8 days from 10-29 to 11-06, installs went up 291k, but ratings only rose by 574, roughly one rating for every 500 installs. Users were pulled in by ads and didn't engage much after installing.
On the charts, the French Tools free chart had it at #10-29 and #10-30 in the 2 stretch and #16 overall. By 11-06 it dropped to #6 in Tools and #50 overall. Germany fell from #10 to #25, and the Netherlands, Poland and Spain all dropped beyond 100th. Hong Kong held between #3 and #5, and Brazil climbed from #27 to #17 (Google Play charts, 11-06). The peak has passed: Europe is fading, while Hong Kong, Macau and South America are holding up.
Where users come from: paid acquisition, aimed at France
Almost nobody outside the store talked about it. No press coverage, nothing found on X in nearly 60 days, and a TikTok search for its French name only returns Windows cleanup tutorials. To figure out where the traffic comes from, you have to look at what's inside the app.
It integrates Adjust (to see which ad each install came from and what it's worth), and the monetization side stacks nearly 30 ad networks: AppLovin MAX, Appodeal, ironSource, Mintegral, Pangle, Unity, Vungle, Meta Audience Network, Yandex and more (Exodus, 10-11). This is the standard setup for "buy installs → multiple ad networks bid to show ads → calculate returns, and keep adding budget while returns are positive." Add the stair-step curve, the 500:1 install-to-rating ratio, and reviews like "installed by accident," and the read is paid user acquisition (inferred, high confidence; we didn't see the specific creatives or channels. Meta, Google and TikTok European ad libraries returned nothing for the package name, but those libraries are incomplete to begin with).
Why France? The French Tools chart had 11-06 at #1 to #5, alongside PDF readers, Mondial Relay parcel tracking, Google Authenticator, Hello Watt and La Poste's digital ID, and 6 cleaners sat in positions #14 to #5. A few tens of thousands of installs a day is enough to crack the top spots. French ad CPMs are also far higher than in the Philippines or Nigeria, and there's less competition for paid buyers than in the US. Titles and descriptions were translated into French. From the tone of the reviews, the users tend to be older and self-described "beginners," the ones most likely to respond to "your phone is full" messaging (inferred).
Where the money comes from: ads shown in the days after install
There are no in-app purchases and no subscriptions. All revenue comes from in-app ads. The business doesn't rely on retention: it buys an install for a certain price, then tries to earn back more from the ads shown during the next few days, and keeps spending if the return is higher. Changing the home screen, floating entry points and notification sounds all squeeze out extra impressions during those days. The cost is reputation. Of the 79 French reviews we pulled, the 1.1 version averages 3.65, with 16 one-star reviews, yet the page displays 4.0 stars (Google Play, 11-06). Neither revenue nor acquisition costs are public, so the outside world can't see how much it earns. The best we can infer from "still adding volume in waves" is that returns are positive (inferred).
The page score is also suspicious. In one version of the French store page, the pinned reviews were short English comments from users with Indonesian and South Asian names: "good" marked helpful by 29 people and "five years old" by 5 people (11-06). The content is empty, yet a lot of people marked them helpful, which looks like manufactured engagement (inferred, not verified).
Who's behind it: a shell-developer factory
The developer registered on the store is S.N. Media, with an address in Uttar Pradesh, India. But when you put it next to several cleaners from the same period, the structure is identical:
- Package names all follow a "function word + three to five random letters" pattern: .umm, .edo, .sffps, .lter, .zwwv, .leee, .qiea;
- Privacy policies are all hosted on Google Sites, the developer website is a jumble of a domain, and the contact email is Gmail;
- The developer names are all over the place: an individual in India, "Jhundoo Lal", a French village heritage association, a technology company in Tianjin;
- All were listed between 2026 and July in 5, targeting Europe plus Hong Kong and Taiwan, each with 150k to 1.03M installs (Google Play, 11-06).
The same account also runs a PDF toolkit with only 32k installs, sold via in-app purchases. Our read is that the same publisher (or the same outsourced template) is spreading volume across multiple borrowed accounts, testing every category and adding budget to whichever one returns positive. Quick Clean Space is the one that performed best in this batch (inferred from structural evidence only; no company registration or signing-level evidence).
Who it's competing with: hundreds, even thousands
| Product | Scale (Google Play, 11-06) | How it differs |
|---|---|---|
| Files by Google | 8B+ installs | Free, no ads, many preinstalled on phones, same features |
| Cleanup: Phone Storage Cleaner(Codeway) | 36.5M, 7 days +960k | Subscription model, #1 on the multi-country utility Top Grossing chart, heavy investment in brand and creative |
| Smart Clean Pro(Rangana Global Studio) | 7.91M, #7 in French Tools | The same ad-cleaner model, older and bigger |
| CleanX(TapSuite) | 4M, 7 days +510k | Has in-app purchases and subscriptions |
| Phone Clean Fix(Luvasa Distro) | 278k, listed 10-22 | Same playbook, #8 in French Tools |
| Hyper Cleaner and others (JTR Labs) | 980k / 1.15M, 7 days +810k / +670k | Account rotation, targeting the US and Canada |
| CleanMax, EasyClean, NovaClean and others | 130–6M | Targets cheap-traffic markets like the Philippines, Nigeria and South Africa |
At least 2026 cleaners that launched new in 7 and gained 100k+ in 40 days. It has no functional differentiation. The only difference is that it chose France and Hong Kong.
If it were you
Bottom line: This is an arbitrage business built on user acquisition. What you can learn is the playbook, not the product. Building another cleaner along the same lines will most likely just be paying the ad platforms tuition.
Who it suits: Tool-app factories that already have a user acquisition team, an ad monetization backend, and can run a dozen-plus packages at once. For them, the most valuable takeaway is market selection: look for countries where "low Tools chart barriers × high ad CPMs" meet, like France, Germany or Hong Kong, and localize titles and descriptions.
Who it doesn't suit: Indie developers without a paid acquisition budget who hope to grow through store search or content. Cleaners have no organic traffic, and word of mouth won't help you. Files by Google is free and preinstalled.
How to do it: Ship the same codebase as several packages with different names and languages, test each with a small budget for three to five days, and only scale the ones with positive returns. Don't copy the home-screen changes, notification bombing or fake reviews. Google Play's policy enforcement targets exactly those, and one banned account takes the rest down with it. If you want a cleaner version, you could follow Codeway's approach of subscriptions and a stronger brand, but that's a different and more expensive path.
How to acquire users: Google App install ads, Meta, programmatic ad networks, with creatives built on the "your phone storage is almost full" pitch. Targeting people over 50 who aren't very comfortable with their phones works best (inferred).
When to get in before it's too late: Its French chart position dropped from #2 to #6 within a week, while new packages using the same playbook keep appearing every week. If you want to exploit the "French Tools chart" gap, think in months, and the window is closing.
What would show you're wrong: If installs in November climb again in waves and the German and Dutch rankings return, returns are better than they look and budget is still growing. Conversely, if it and the other same-template shell apps disappear from the store together, the risk of this playbook is outpacing its reward.

Why Quick Clean Space (com.quick.clean.clean.umm) got this far
Channel: Google Play | Developer: S.N. Media (store page registrant ABDUL ALEEM, Etawah, Uttar Pradesh, India) | First listed: 2026-07-13 | Research date: 2026-11-06
Bottom line
It has no product differentiation. It's a templated "cleaner + ad monetization" shell app. It scaled after launching version 2026 in early October 1.1: most likely paid acquisition (Adjust attribution plus 30 ad SDKs such as Appodeal and AppLovin), mainly targeting France, with secondary pushes in Hong Kong, Germany and Brazil. The French Tools category has a low bar: a few tens of thousands of installs a day can reach #2. The reviews section also shows signs of suspicious padding. The money comes from in-app ads, with no in-app purchases. It has passed its peak and is now declining.
1. What it is
- The store listing describes it as a storage cleaner: it finds junk files and large files, and groups blurry and similar photos, "100% local scan". The French listing title is localized as "Nettoyage Rapide de Fichiers" (apkpure, Play France developer page).
- The store listing says "Contains ads" with no in-app purchases (Google Play library app_snap, 11-06
offers_iap=False,ad_supported=True). - Its permissions far exceed what a cleaner needs. Exodus 2026-10-11 analysis of version 1.1: 31 trackers and 27 permissions, including PACKAGE_USAGE_STATS, MANAGE_EXTERNAL_STORAGE, REQUEST_DELETE_PACKAGES, READ_CALENDAR, precise location, and camera (https://reports.exodus-privacy.eu.org/en/reports/com.quick.clean.clean.umm/latest/). The store's data safety section also lists collection of photos and videos and calendar, and sharing of app activity and device IDs with third parties (Play store page 11-06).
- What users actually experienced: after version 1.1, French reviews started showing a batch of complaints: "changed my whole desktop layout", "my home screen filled with stuff I don't want", "can't uninstall it", "too many ads", "ringtone keeps going off, can't sleep" (googleplay library review table, see section 4). My guess is that version 1.1 added methods to take over the home screen or floating entry points, plus notification bombardment, to boost ad impressions (unverified; the only basis is the reviews).
2. Growth data
| Timeline | Total installs | Daily average | Source |
|---|---|---|---|
| 2026-08-12 | 13k | About 2,000 | AppstoreSpy estimate (googleplay.app_day_ext) |
| 2026-09-15 | 101k | 2–5 thousand | Same as above |
| 2026-10-03 | 150k | 2–4 thousand | Same as above |
| 10-04 to 10-15 (around the launch of version 1.1) | 150k → 402k | 10-12 to 10-15, roughly 4.2–50k per day | Same as above |
| 10-25 to 10-27 | 480k → 530k | 2–26k per day | Same as above |
| 10-29 | 530,427 | — | googleplay library app_day |
| 10-30 to 11-03 | → 768,300 | About 48k per day | Same as above |
| 11-04 to 11-06 | → 821,827 | 1.6–22k per day | Same as above |
- Over the 8 days from 10-29 to 11-06 it gained 291k installs, and its rating count went from 1,229 to 1,803 (+574). The ratio of new installs to new ratings is about 500:1, which is typical of paid or pop-up-driven traffic: users arrive and barely interact.
- The curve comes in steps: a wave at 10-04, 10-07 to 10-09, 10-12 to 10-15, 10-25 to 10-27, and 10-30 to 11-03, with almost nothing in between (10-05 only 13, 10-10 only 38, 10-16 only 123, 10-28 only 48). It looks like budgets being turned on and off in tranches, not the continuous curve of organic traffic.
- Chart ranks (googleplay.chart_rank, Top Free):
- French Tools 10-29, 10-30 #2,11-06 #6; French overall chart fell from 16 to 50.
- German Tools fell from 10 to 25, Netherlands from 50 to 162, Poland from 43 to 128, Spain from 58 to 124, Taiwan from 39 to 68.
- Hong Kong Tools has stayed between 3–5, Brazil rose from 27 to 17, Indonesia from 97 to 89.
- 11-06 has charted in 11 stores, and Canada dropped off the chart after 11-02. Overall, Europe is fading while Hong Kong, Macau and South America are holding up.
- Third party: AppInsider estimates it downloads 10k+ per day, has charted in 23 of the 10 countries it tracks, and has repeatedly posted "weekly downloads ×2.7 / ×3.6" (https://appinsider.io/android/app/com.quick.clean.clean.umm).
3. Competitors
Plenty of products do the same thing (Android storage cleaning), and the system ships with it too:
| Competitors | Platform | Launched | Scale (googleplay library 11-06) | How it differs |
|---|---|---|---|---|
| Files by Google | Big-company features | 2017-12 | 8B+ installs, 7 days +23.4M | Free, no ads, preinstalled, same cleaning features; Quick Clean is just a different wrapper |
| Cleanup: Phone Storage Cleaner(Codeway) | Android | 2025-11 | 36.5M, 7 days +960k, #1 on Tools Top Grossing across several countries | Subscription-based, heavy spend on brand and creative; Quick Clean is free and relies only on ads |
| Smart Clean Pro(Rangana Global Studio) | Android | 2025-09 | 7.91M, 7 days +150k, #7 in French Tools | A similar ad-driven cleaner, but older and much bigger |
| CleanX(TapSuite) | Android | 2026-05 | 4M, 7 days +510k, #14 in France | Has IAP and subscriptions, has reached the Argentina Top Grossing chart |
| Phone Clean Fix(Luvasa Distro) | Android | 2026-10-22 | 278k, 7 days +278k, #8 in France | Same playbook (shell developers, paid acquisition, ad mediation), riding the names of older apps |
| Hyper Cleaner / Smart Clean Pro(JTR Labs) | Android | 2026-09 / 10 | 980k / 1.15M, 7 days +810k / +670k | Targets the US and Canada with account rotation; Quick Clean targets France and Hong Kong |
| CleanMax (Nitrogen Cloudless), EasyClean, NovaClean and others | Android | Around 2026-06 | 130–6M, 7 days each +30–700k | Targets cheap-traffic markets like the Philippines, Nigeria and South Africa |
| Same template shells: Smart Clean Tools (.edo), Pocket Storage Cleaner (.sffps), Clean My Files (.lter), Space Clean Tools Pro (.zwwv), Storage Space Manager (.leee), Space Master Clean (.qiea) | Android | 2026-05 to 07 | 15–1.03M, 7 days each +2.5–120k | Nearly identical to it, see section 5 |
| Quick Clean - Space Cleaner(SyberTown) | Android | 2025 ago | Has SEO articles and a BlueStacks page, not in our chart database | Older apps with almost identical names, possibly picking up some same-name search traffic (unverified) |
Bottom line: there are hundreds or thousands of competitors, and it has no functional differentiation.
4. Where users come from and why they stay
Paid acquisition, mainly in France (highly likely, I haven't seen the creatives directly)
- It has Adjust attribution SDK; on the monetization side it stacks nearly 30 ad networks, including Appodeal Stack, AppLovin MAX, ironSource, Mintegral, Pangle, Unity, Vungle, InMobi, Fyber, Chartboost, BidMachine, Yandex, myTarget and Meta Audience Network (Exodus). This is the standard setup of "buy installs → monetize through ad mediation → back into bids based on ROAS".
- The curve is stepped, the install-to-rating ratio is about 500:1, and there is no social or media exposure at all.
- One French review says "j'ai installé cette application par hasard" (I installed it by accident). Another review with 283 helpful votes says "I spent a whole day and night trying to install a cleaner, and a bunch of other apps popped up". That suggests users were led in through ads or pop-ups.
- Category background: a US carrier store employee warned on Facebook that these "cleaning / storage expansion" apps mostly come from Facebook ads along the lines of "your phone has 27 viruses" (https://www.facebook.com/groups/SiskiyouGrapevine/posts/25777486291913757/, 2026-01; it's about the category, not this app).
- Our Meta, Google and TikTok (Europe) ad libraries show nothing for these 6 template-style package names. Those libraries only track products on our list, so finding nothing doesn't mean they aren't advertising.
Why France is the main market
- In the French Tools chart, ranks 1–5 are PDF readers, Mondial Relay, Google Authenticator, Hello Watt and La Poste identity, and 6–14 includes 5 cleaners (googleplay.chart_rank 11-06). In other words, a few tens of thousands of installs a day is enough to land near the top.
- France is a major European market with much higher ad eCPMs than the Philippines or Nigeria, yet its user-acquisition competition is less crowded than in the US. The title and description are both localized into French.
Rating management (suspicious, unverified)
- On the French listing it shows a rating of 4.0 with 1.78K ratings. Pinned at the top, though, are short English reviews: Dede Andhika "good", 29 people found it helpful; Dimas Martinez "good", 19 people found it helpful; sayed sd patwary "five years old", 5 people found it helpful (Play store page 11-06, gl=fr). The names are mostly Indonesian and South Asian, the content is meaningless one-word text, and yet the helpful counts are substantial.
- Among the 79 French reviews we captured: the 1.1 version averages 3.65 stars, with 16 of them 1 stars; the 11 reviews without a version average 2.55 stars (googleplay.review). Real user word of mouth is clearly worse than the page score.
Why users stay: there is essentially no retention mechanism. Negative reviews focus on intrusive changes to the desktop, can't uninstall, too many ads, and disruptive ringtones. Apps like this don't make money from retention. They make money when "ad impressions in the days after install exceed the cost of that install".
5. Who is behind it: a templated shell-app factory
- Package names all follow the pattern "function word + random 3–5 letter suffix": .umm, .thrs, .edo, .zwwv, .sffps, .lter, .leee, .qiea.
- Privacy policies are all hosted at
sites.google.com/view/privacy-<name>; developer websites use gibberish domains (rgndjjkdiw.com, happywws.com, ywusws.com, vfmieds.com, techwcat.com, suntessw.com, kukinltd.com); contact emails are Gmail addresses. - Developer names are all over the place: an individual Indian developer S.N. Media, "Jhundoo Lal", a French cultural heritage association "MEMOIRE ET PATRIMOINE DE SAINT HILAIRE D'OZILHAN", a technology company in Tianjin, BX LIDA and others. It looks like borrowed or acquired developer accounts. AppBrain shows S.N. Media active since 2023, earlier than both of these apps.
- All were listed between 2026-05 and 07, and they also target Europe plus Hong Kong and Taiwan: Clean My Files has charted in 10 stores, Space Clean Tools Pro in Germany, Spain, France, Hong Kong and the Netherlands, and Smart Clean Tools in Spain, France, Hong Kong, Italy, Poland and Vietnam (googleplay library 11-06).
- Another app on the same account, PDF Toolkit Pro (.thrs, 2026-05), has only 32k installs and sells IAP at $0.99–34.99. That shows the factory spreads across every category and adds budget to whichever one takes off.
- My read: this is one publisher or one outsourced template running volume across many accounts, and Quick Clean Space is the best performer of the batch. It grows because it was picked to get more budget, not because of the product itself.
6. How visible it is
- No media coverage and no X discussion (x-radar searched "Quick Clean Space" over the last 60 days and found no relevant results). A TikTok search on the French name returns only Windows cleaning tutorials.
- Revenue is not public. It only shows up on aggregator pages such as AppInsider, Similarweb, AppBrain and apkpure.
- The category itself is extremely crowded: 15 of the top 5 French Tools apps are cleaners, and at least 2026 cleaners worldwide were newly listed in 7 year and grew by 100k+ in 40 days (googleplay.app_profile).
7. Differentiation
There's no feature difference. What sets it apart is the playbook: picking France and Hong Kong, markets where the Tools chart is easy to reach and ad rates are decent, localizing the language, layering heavy ad mediation (30 networks bidding), and spreading risk across a set of template shells, rotating budget among them. This playbook is in fact why it succeeded, but it's shared by most of the shells in this batch, not unique to it.
8. Takeaways
- Market selection: skip the crowded US Tools chart and look for regions where chart barriers are low and eCPM is high, like France, Germany, and Hong Kong, then localize titles and descriptions.
- Sock-puppet matrix: the same codebase with swapped package names, names, and accounts, several apps tested at once on small budgets, and scale up whichever ones show positive ROAS. Random-suffix package names, Google Sites privacy pages, and gibberish domains keep listing costs at a minimum.
- Monetization: heavy SDK mediation plus Adjust attribution, using ad LTV to back-calculate paid acquisition bids.
- Risk: invasive desktop changes, notification spam, and suspicious five-star reviews all sit in Play policy gray areas, so takedown and account-ban risk is high. This model depends on constantly rotating sock puppets.
9. Uncertain
- Their ad creatives aren't visible, so it's unverified whether they buy through Google UAC, Meta, or programmatic traffic.
- Unverified whether "changing the desktop" means the app sets itself as the default launcher or uses overlays, shortcuts, or similar tricks.
