210k installs, not a single rating: how ThemeBox was "bought" with ads

An developer account called Infinity Store listed an app on Google Play in late July: a wallpaper-and-icon app named ThemeBox. It had fewer than 250 installs in its first two months. In early October it ran two short video ads on Facebook, and a month later installs had reached 210k, yet the store page still has not a single star. This piece explains what drove it, why it's not worth copying, and what's genuinely worth learning from it.

Oct 6, a Halloween ad

On the morning of Oct 6, 2026, a Facebook page called "ThemeBox: Icons & Wallpapers" posted a vertical video titled "+1000 Halloween Themes, Wallpapers, Widgets, Icons & Control Center". By November, the video had 9,200 views, 8 likes and no comments. Five days earlier, the same page had posted another one, "5000+ Themes Beyond Default. Switch Now", with 4,500 views.

The page is categorized as "Just for fun", has single-digit followers, has posted nothing but ad-style videos like these, and the developer also set up a second page with the same name for this app. It's a page built purely to run ads.

The install curve changed course right around these days. Google Play installs: cumulative 24 in August, 86 in October 1 249; from October 2 onward about 470 a day, from October 7 onward about 2,400 a day, and on October 12 and 13 it added 25k and 22k over those two days.

What it is

A fairly ordinary Android personalization app. The store listing advertises four things: HD / 4K wallpapers (AMOLED, minimal, anime, space, neon, cars, and more than a dozen categories), icon packs (minimal, rounded, glass, macaron colors), desktop widgets (clock, calendar, battery, weather, photos, quotes), plus bundled "theme collections". Free to download, with ads; in-app purchases run $3.99 to $16.99 each.

This "wallpaper + icon + widget" trio already has a crowd on Play: Themepack, iThemes, Themely, WidgetKit, with installs ranging from 600k to 120M. ThemeBox's listing reads almost word-for-word like theirs, with nothing exclusive.

The curve looks like a faucet

Plot daily installs and it doesn't climb slowly, it comes in bursts:

Source: Google Play installs, cumulative 11-06 as of 210,099, +7k over the last 60 days.

Over twenty thousand a day, then dropping to zero the next, is what budget-gated ad spend looks like, not word of mouth or store recommendations. The charts it has hit say the same: it has only appeared on the free chart under "Personalization", and the countries keep rotating. At the end of October it was India, Saudi Arabia, the UAE and Indonesia; later it moved to the Philippines, Brazil and South Africa. In November its best showings were Brazil #6, Indonesia #40, the Philippines #86 and South Africa #93 (127). These are all markets where ads are cheap. The ad-buying countries rotate, and the charted countries rotate with them (inferred). It has never made the overall or Top Grossing charts.

210k people installed it, and not one rated it

What stands out more is the ratings. The developer's other apps show star ratings on their store pages: short-drama app ShortNext 4.3, DramaGo 4.6, ShortTwist 5.0. ThemeBox alone shows no stars; its rating count is 0, and its reviews are 0.

An app installed 210k times with no displayable rating at all most likely means people rarely open it, and when they do they don't stay; that is typical of cheap paid traffic (inferred). It's also possible Play judged the installs suspicious and hid the ratings; from the outside you can't tell which. Either way, there is no organic retention.

Why it's called ThemeBox of all things

Play already has two big apps with the same name: Fusion Flow Tech's "Themebox - App icons, Widgets", listed in August 2025, with 13M installs and 239k ratings, still running ads on Google; and EZProducts' "Themes Box: Icons & Widgets", with 5.75M installs.

Infinity Store's package name is even com.themebox.wallpaper. Some people searching "themebox" on Play are looking for the genuine 13M-install app and may install this one by mistake (inferred). But the curve is bursty, so the name-borrowing brings only a small base; the main driver is still ads.

Borrowing names is standard for this developer. Its short-drama app DramaGo collides with another DramaGo that was already running ads on Facebook.

Who's behind it

Infinity Store's developer page has only one line, "Bringing you limitless digital experiences"; its website is a Google Sites page, and each app's site is a one-pager on blogspot, sites.google.com or workers.dev; the contact email is gmail. Who is behind it and which country they're in can't be determined.

But what it's doing is clear: from July to October 2026, this one account shipped ShortNext (short drama, 2.59M installs), DramaGo (short drama, 1.21M), ShortTwist (short drama, 220k), VivaShort (AI short drama), a PDF reader, couple stickers, an AI companion chat, plus ThemeBox, for roughly 4.27M total installs across the account (Google Play, 11-06). Pick a hot category, borrow a hot name, mass-produce apps, and add budget wherever the ads pay back. Within that, ThemeBox is just a test category, a small account next to its short dramas.

Where the money comes from

The old playbook for personalization apps: pop interstitials on open, unlock themes by watching rewarded videos, plus in-app purchases for "remove ads / premium themes". Install costs in India, Indonesia, the Philippines and Brazil are low, a few cents to a dime or so each (estimated), and the ad impressions from a user's first few opens are meant to pay it back.

Whether it actually makes money can't be seen. It never reached the Top Grossing chart, in-app revenue is invisible, and zero ratings suggest very short user sessions, so the ad impressions it can capture are limited (inferred). The curve keeps rising in bursts, which suggests that for now the developer still thinks it's worth keeping the faucet running.

Who it's competing with

Almost everyone. Personalization is one of the most crowded categories on Google Play; on the same week's rising-installs chart, apps like Control Theme, Theme Widgets and iControl each gained over 800k, and ThemeBox's 60k is a rounding error. Above them sit pure-wallpaper giants like Zedge (660M installs) and Wallcraft (180M), plus the 1.4B-install Google Wallpapers that ships with the phone.

It has no followers of its own, because it is itself a follower.

If it were you

C. Don't copy ThemeBox. The product has no differentiation, the category is saturated, users don't stick around, and the only traffic source is ads that you can also buy and that everyone else is buying. What's worth learning here is the playbook, not the product.

Who it suits: small teams already running Facebook / Meta short-video ads, holding an ad-monetization SDK, and able to ship a build within a week, using a cheap category as a place to practice building an ad-buying model.

Who it doesn't suit: indie developers who want a personalization app people use for years, earning through word of mouth and subscriptions. This playbook delivers neither retention nor ratings; what you end up with is a curve that drops to zero the moment the ads stop.

How to do it: if you want to build in personalization, stop making three-piece bundles and build something with a specific selling point, like a single style that follows system aesthetics (glass, pixel, a particular holiday), or themes tailored to one phone model. If the goal is just practicing paid acquisition, follow its path: run several categories under one account, test in cheap countries on a small budget first, and scale whichever pays back.

How to acquire users: Facebook Reels ads, one creative per number and scene ("5000+ themes", "1000+ Halloween themes"); post seasonal creative a week early, the next ones being Christmas and New Year. Target cheap markets like India, Indonesia, the Philippines and Brazil.

When to be ahead of it: Christmas-themed creative needs to be running by mid-December; after New Year, click-through on holiday creative in the personalization category drops off.

What would mean you read it wrong: ① ThemeBox's rating count starts rising and real user reviews appear, showing it has retention and isn't just bought traffic; ② it charts on some country's Top Grossing, showing in-app purchases really do collect money and this category's paid acquisition pays back better than expected; ③ conversely, if the curve goes fully to zero before December and never pulses again, that shows even the developer couldn't make the numbers work, and this path is even less worth taking.
