How an "ads-only" heart sticker pack reached #1 on the UAE personalization chart

Emoji Love Wallpaper WASticker is a romantic sticker-plus-love-wallpaper bundle for WhatsApp on Google Play. It launched in Aug 1, hit 450k installs in its first week of November, and climbed the personalization charts in 30 countries at the same time. The product itself isn't much to write home about. What's worth a look is the playbook behind it: the same team runs 4 developer accounts and has shipped 12 near-identical romantic sticker apps this year, adding up to roughly 31M installs. Here's the breakdown: what it is, why it surfaced this week, where the traffic and money come from, who's competing, and whether you can use this playbook.

One one-star review, and a single-day 210k

On Oct 7, a user in India gave it one star with a line: "The developer made this just to show the ads it is ads not else" (the developer made this only to show ads, nothing else).

He wasn't wrong. Three-plus weeks later, this "nothing but ads" app took off: Google Play installs went from 10-31 to 356k, then 11-01 to 454k, 11-02 to 667k, gaining 213k in a single day; by 11-06 it was at 805k. Over the same period it climbed the UAE personalization free chart from #25 to #1, moved India and Saudi Arabia from #22 to #2, reached #3 in South Korea, sat at #9 in Japan, Hong Kong and Turkey, #16 in Germany and Indonesia, and climbed from #153 to #50 in the US.

Its version number has been 1.0.5 the whole time, and the last update was Sep 14. The product hasn't changed at all.

What it is

Open it and you get screens of stickers: I Love You, kisses, hugs, roses, good morning/good night, birthdays, Christmas. Tap "Add to WhatsApp" and they go straight into your chats. The other half is heart and couple wallpapers, set as your lock screen in one tap. The store listing runs thousands of words, cramming in search terms like Love Stickers for WhatsApp, Romantic Couple Stickers, Love Emoji, GIF, Animated Stickers and Love Wallpapers, and ends with "Completely Free."

The free part is real: no in-app purchases, and it has never charted on any grossing list. All the money comes from ads. Its app-ads.txt authorizes three networks: Google AdMob, Meta Audience Network and Tappx.

Why it surfaced this week

Two things are certain.

The category shifted. Romantic sticker packs used to sit crowded together in the "Communication" category. The same team's near-identical sibling, Romantic Stickers WAStickers, is still there with 8.52M installs and identical rivals. This one changed its title to "Emoji Love Wallpaper WASticker", added wallpapers, and moved into "Personalization." Its rivals there are general wallpaper platforms like Zedge (659M installs), and romantic stickers have almost no direct competition in that category, so it shot up to #1.

It's not one app, it's a matrix. The developer website uses a free app-ads-txt.com hosted subdomain, and the ad accounts can be read from it. Comparing them shows that Stickorax and two other accounts, Exdev Apps and Kalmzee, share the same Meta ad monetization ID; Exdev and Kalmzee also share an AdMob account with a fourth account, Future Sole; and Stickorax itself has an app hosted under Exdev's subdomain. With four developer names, it's safe to conclude they're one operator.

All 12 packages were published this year with the same assets: swap the package name, the title and the account, then publish again. Multiple accounts spread the takedown risk and also grab more slots in search results.

On the uncertain side: in this November wave, 5 countries began climbing on the same day at almost the same pace. The product hasn't been updated, and the rating count is only 0.14% of installs (1,099 ratings, 3.5 stars). That looks like Google's app promotion ads scaling up, or Play placing it in featured slots (inference, I couldn't find any ad-spend records). Not finding records doesn't mean there was no spend. And since this crew has 12 packages monetizing at the same time, reinvesting ad revenue into paid acquisition is the standard move for this kind of matrix.

Where users come from and why they want it

Users are in the UAE, Saudi Arabia, India and Southeast Asia, where WhatsApp is the main messaging app. They send good mornings, good nights, miss-yous and birthday wishes every day, and they want flashy, text-laden "cheesy romance" stickers with roses and hearts. WhatsApp's official sticker store and AI stickers are clean but don't do this. Gboard's Emoji Kitchen doesn't either. That gap has been filled by generic no-brand sticker packs.

How big the demand is shows up on TikTok. The Latin American sticker creator @paraguayita_01 posted one video in June, "#stickerscoquetos flirty stickers, code 8B0HHJ, only on Sticker.ly," that reached 35M views; in October a Portuguese video, "copy the code into Sticker.ly to get the best love stickers," got 800k; an Arabic one, "come see your stickers," got 650k (TikTok, 11-06). Note that nearly all of this traffic flows to platforms with communities like Sticker.ly, not to Stickorax and its peers. Searching X and TikTok for its name turns up nothing. This matrix runs entirely on the store, with no content behind it.

Do users stay? Once stickers are installed in WhatsApp they keep being used, but users don't need to reopen the app. So the ad money comes mainly from interstitials and rewarded videos shown on first open: you earn once per install.

Where the money comes from and how much it makes

Ads only. Three ad networks bid together, and showing one before each "Add to WhatsApp" is standard practice for apps like this.

No public revenue figures. A rough estimate: for a utility app like this, a new user's lifetime ad revenue might be a few US cents in India and tens of cents in the UAE and Saudi Arabia. 12 packages with 31M installs this year come to over a million dollars at an average of 5 cents per install, with almost zero asset cost. If it's buying paid acquisition, everything depends on whether the cost per install stays below that number, which can't be seen from outside.

Who it's competing with

The romantic WASticker theme alone already has two or three matrices running it, and more look-alike packs have launched since September.

What's actually worth learning is two things

First, category misplacement. The same product ranks in the dozens in a crowded category full of copies, but moves to an adjacent category with no direct rivals and takes #1 for free through the category chart's organic exposure. The trick isn't limited to stickers.

Second, a no-brand matrix built on zero-cost content. Stickers, wallpapers, ringtones and emoji cost almost nothing to make. One asset set can ship under dozens of package names, carry three ad networks, and earn once per install. It makes money, but it isn't a product; it's a bulk-publishing business.

If it were you

B. The opportunity exists and few people know about it. But what you'd be building is a bulk-publishing and paid-acquisition business, not a product, and the romantic WhatsApp sticker theme alone already has several matrices running it.

Who it suits: small teams that have already published no-brand utility apps on Google Play, own a few developer accounts, can read AdMob reports and run Google app promotion campaigns; ideally they know the tastes of a major WhatsApp market (Arabic, Indonesian, Hindi, Spanish, Portuguese).

Who it doesn't suit: anyone who wants a branded product that keeps users long-term; anyone not prepared for a Play account to be banned (Google Play has policies against "repetitive content" and multi-account bulk publishing, and this crew could be taken down all at once); anyone who can code but can't work out whether paid acquisition pays back.

How to do it: stop making English romantic stickers. Change the theme or the language: holiday stickers for Ramadan and Eid, Diwali, Christmas and New Year; local text stickers such as Arabic love phrases or Indonesian good-morning greetings. One pack per theme, bundling stickers with wallpapers, first aiming for the personalization category and seeing whether it can break into the top 10 in a few countries. Generate assets in bulk with AI; a few hundred stickers per pack is enough. For ads, use AdMob plus one or two bidding networks, and place interstitials before "Add to WhatsApp."

How to get users: step one is store search and category charts, with the title packed with local-language search terms. Step two is what this crew isn't doing: TikTok. The Latin American creators' "copy the code for stickers" videos can reach millions to tens of millions of views. You can find local sticker creators and have them post with a "link in bio," or open your own account and post a daily sticker preview. Once a pack pays back, reinvest the ad revenue in paid acquisition.

Deadlines: holidays are hard deadlines. Christmas and New Year packs need to be live by early December, Valentine's packs by late January, and Ramadan packs (which start in early February of 2027) by mid-January.

Signs you've misread it: ① Packages from accounts like Stickorax and Exdev get taken down by Play in batches over the next month or two, which means the matrix window is closing; either build one product per account honestly or stay away; ② after a pack breaks into the top 1, installs quickly fall back to a few thousand a day, which means the wave was propped up by paid acquisition and payback may be harder than it looks; ③ WhatsApp launches localized holiday or love-phrase stickers, or AI stickers add Arabic or Hindi text, and the gap closes.

Data and sources: Google Play install counts, ratings, personalized free charts (30 storefronts, 10-29 to 11-06); Google Play store page descriptions and reviews (11-06); each developer's app-ads.txt (he93803ee, yf5c8bce1, ifee5490f and other subdomains, crawled 11-06). The four accounts being one operator is inferred from shared ad IDs. TikTok sticker-video view counts from @paraguayita_01, @regi_sccp, @algej3 and others (11-06). Searches for "Stickorax" on X and TikTok returned nothing (11-06). Ad revenue is estimated; paid acquisition is inferred.
