A borrowed name, 125k installs: ThemeArt and a reskinned-app pipeline

ThemeArt, a theming app that launched at the end of October, went from 8 installs to 125k in 179 days. The product itself has nothing new. The name borrows a top-ranked iOS hit, the template was used by the same team last month, the ratings look suspiciously good, and the installs were bought in Vietnam, India and the Middle East. What it can actually teach isn't in the product. It's the playbook: find an existing hit on iOS, move it to Play, and run the cycle again on a new developer account.

A five-star review that's just a name

Oct 28: a five-star review on Google Play for ThemeArt came in with nothing but a name, "Hasan Islam", followed by a long string of red hearts. Most reviews that week looked the same: "রনি" (a Bengali name), "နန်းပွင့်သိဂ်ီ" (a Burmese name), "NimaDangi", or just a row of emojis. Nov 5, a one-star review had the body "Tap on a clip to paste it in the text box.", which is an Android keyboard clipboard prompt pasted in as-is.

Only 76 reviews have visible text, but the app has 2,659 ratings (Play listing, 11-06). That means most people just tapped a star on the in-app rating prompt, and the few who wrote something didn't know what to say. This matters later: half of why the app took off is these stars.

What it is

ThemeArt: Themes Widgets Icons, from developer "Hermesy", launched on Google Play on 2026-10-07 and filed under Personalization. One app bundles four things: whole-phone themes, home-screen widgets, icon swapping, and an iOS-style "Control Center" pull-down panel (built on Android's accessibility service, with a dedicated note on the store page). The listing sells "cute, pastel, minimal, aesthetic": soft pink, lavender, Halloween, winter, one tap to make an Android phone look like a cute iPhone.

Money comes two ways: ads (its website's app-ads.txt lists AdMob, Vungle and Meta), plus in-app purchases at $0.99–$20.99. The most common complaint in reviews is also about ads: "too many adds", "this app scams u 50 plus ads and more".

How fast it grew, and where

(Google Play installs and rating, logged daily)

Growth came in steps: +8K, +69K, +25K, +23K. Charting countries were added in waves too: first Vietnam, India and Thailand (10-29), then Saudi Arabia and Turkey (10-30), then the UAE, South Africa, Indonesia, Malaysia, Brazil, Nigeria and Argentina all at once (10-31). The Philippines, Mexico and the UK came in 11-01, and the US, Poland and Italy in 11-04. 11-06 It shows up on the Personalization Top Free chart in 19 countries. Its best rank is #11 to #13 in Vietnam, and it climbed from #183 to #26 in India. In the US it only reached #190, never the overall or Top Grossing charts.

Going into cheap markets first, then adding a few countries a day, gives a stair-step install curve. That's the classic paid-acquisition rhythm. (Inference: which ad networks it buys on, and how much, isn't visible from outside. I found no TikTok videos or press coverage of it online.) In places like Vietnam and India, a few tens of thousands of installs can push an app into the top 30 of the Personalization Top Free chart, and once charted the chart itself brings in some organic installs.

Those stars

11-01's numbers: 8,557 installs, 874 rating, roughly 10% of installers left a rating, and 874 of those ratings are five stars. For comparison, Hypernova's similar app ThemeFlow has 618K installs, 681 ratings and an average of 3.5. ThemeArt's rating rate is about 20 times higher, and its two- and three-star counts have stayed at zero.

The likely approach is that the app first asks "Do you like it?", and only people who tap yes get sent to rate it on Play (inferred; it could also be more direct). That long run of reviews that just list a name look like users being pushed by a popup into rating it. 11-05 Starting from one-star reviews, it reached 233 by 11-06, and real complaints began to come in. An Iranian user wrote in Persian on 11-02: "Totally useless, don't waste your data. I knew it would be like this, but I tried it anyway."

An app with a near-perfect score on its store page converts better than one at 3.5 stars. In a category where every app does the same things, those few stars may be the only thing setting it apart.

The name is borrowed, the template is used

The name "ThemeArt" belonged to Hypernova Limited on iOS. Their "ThemeArt: Widgets & App icons" launched 2026-05-28, hit #1 on the US App Store Personalization chart, and has 5,278 ratings. Hypernova's Android version doesn't use that name (it's ThemeFlow), so the ThemeArt name sat unclaimed on Play and got taken.

Hermesy's whole Play lineup maps almost one-to-one onto Hypernova's: Silly Smile live wallpapers, battery emoji, DIY wallpapers, plus themes, all things Hypernova had already validated on iOS. But the ad accounts don't match (none of Hermesy's IDs appear among the 89 AdMob publisher IDs Hypernova has made public), so Hermesy looks more like an independent copycat than a Hypernova alt account (inference; not fully ruled out).

Digging further, Hermesy has a sister developer account, "Nova AI Global". The two accounts' app-ads.txt files are identical, they use the same AdMob account, and their websites were committed by the same GitHub user. Nova AI Global published ThemeMix: Themes Widgets Icons on 9-08. From the name, package and features, it's clearly the previous version of ThemeArt. It reached about 190K installs, dropped off every chart in early November (Play listing shows 11-06: 194,515), and its early ratings were nearly all five stars too. When the first one stopped moving, they switched accounts, names and icon sets, and launched again.

The website catalog for this operation is numbered: 012-beauty-cam, 019-mp3-cutter, 032-theme-widget, 039-emoji-battery... ThemeArt's number is 057. The two accounts have 11 apps between them: a dog-language translator, a prank video call with Santa, expense tracking, WiFi, PDF and weather tools. Only two theme apps passed 100K; the rest stayed under 10K (Play developer pages, 11-06).

Who it's competing with

Nearly everyone. The category is already mature on Play:

iControl also does "control center + themes", and its weekly gain is more than six times ThemeArt's total installs. ThemeArt doesn't register here. The table also shows two things: demand is steady, since Android users in emerging markets keep wanting their phones to look like iPhones, and cute styling helps, with top apps adding hundreds of thousands a week; and Themie, launched a year ago, reached twenty million in a year, so latecomers can still win, just not on product novelty.

Where the money comes from

Mostly ads. Theme-app users keep coming back to switch styles and watch rewarded videos to unlock assets, and in places like Vietnam and India installs are cheap enough that ad revenue may cover the cost. It never reached a Top Grossing chart in any country, so how much the in-app purchases brought in is unknown, and whether the whole thing makes money is unverified. What we can say is that the same team went from ThemeMix to ThemeArt, which at least suggests the first one didn't lose enough to make them quit (inference).

If it were you

C. Worth learning a playbook from, but not worth copying this app. It has nothing to defend: features match the top apps with hundreds of millions of installs, the volume is small, and growth came from a borrowed name, prompted reviews and rotating accounts, each of which can get an app delisted or its developer banned.

Good fit for: small teams already building Android utility and personalization apps, with AdMob monetization and low-cost-market acquisition experience, who can ship one package a month. For you, the thing to take is the product-selection method, not this app.

Not a fit for: anyone trying to build a product that keeps users and sells subscriptions long-term; anyone who hasn't bought installs and is counting on organic store traffic; anyone worried about account bans (prompted reviews, name borrowing and running several accounts are all things Play policy explicitly polices).

How to do it: every week, check the rising charts for Personalization, Photo & Video and Entertainment on the US App Store, and look for apps that just broke in but have no same-name version on Play, or whose Android version uses a different name. The functionality only needs to work; match the store copy and icon style to the original. To go further than ThemeArt, fix what it did badly: fewer ads, rewarded videos for asset swaps instead of interstitial bombardment (most one-star reviews complain about ads), or make content local: holiday packs, regional star-themed palettes, local-language widgets, things the cookie-cutter top apps don't do.

How to get users: Google App Campaigns or Meta, starting in Vietnam, India and Southeast Asia, until the app is in the top 30 of the Personalization chart, then add countries in batches. Put keywords into the title and package name (themes / widgets / icons / control). Prompting for reviews is fine, but don't block everyone who might leave a low score. ThemeArt's one-star reviews started clustering after 11-05, and that is the price.

When to move: this kind of name-borrowing window only exists while the original's Android name is unclaimed, and it usually lasts a few weeks to two or three months. Once the original releases its own Android version, or Play has three or four apps with the same name, it's too late.

Signs that you misread it: (1) ThemeArt stops growing before mid-November and drops out of the top 50 in Vietnam and India, like ThemeMix did, living for only a month. That would mean one package buys only one round of acquisition, and the per-package economics may not work. (2) Hermesy or Nova AI Global gets apps delisted or accounts banned by Play, which would mean the risk has materialized. (3) Conversely, if it also reaches the top 50 of Personalization in high-price markets like the US or UK and charts on Top Grossing, its monetization is stronger than it looks, and this tier should be ranked higher.
