Copied name, 650k installs: how a Pakistani utility studio got a new "number locator" shell to scale in 80 days

In Aug 18, an app called Number Locator - Call Location was listed on Google Play. Its name is almost identical to an older app that has been around since 2020 and has 13.8M installs, differing only by a space. It has nothing new in its features, yet by Nov 6 it had 650k installs, about 20k a day over the last week, and it sits on the Maps & Navigation Top Free chart in 25 countries. Below: what it sells, where the traffic comes from, where the money comes from, and which parts of this playbook are worth taking.

One-star review on day nine

In Aug 27, nine days after launch, a user named Vijay Viji left a one-star review: "worst app fake don't install this app." By Nov 6, 151 people had marked it helpful, making it the most endorsed review on its store page. In Oct 14 another came in: "it's a scam don't even try to install" (40 found it helpful).

The same day there was also a five-star review: "Lovely and easiest way to use," marked helpful by 113 people.

Those three reviews are the whole business. Users install it because they believe "enter a phone number and see where this person is." After opening it they find it can't do that, some call it a scam, but by then the install has already been counted and the ad already shown.

What it actually is

The title and icon sell "locate anyone by number." The store description actually says: a "GPS tools app" with a standard map, satellite view, traffic, route navigation, nearby restaurants, hospitals and gas stations, a compass, your own location history, and location sharing with family members with their consent. The "number lookup" part can only show which country, state or carrier a number belongs to, which is a phone-number region and carrier lookup.

The last paragraph of the description is a disclaimer: "does not provide real-time tracking of another person's device using only their phone number." The title pulls people in, and the disclaimer gets the app through review.

The data safety section says location and device IDs may be shared with third parties, the data is not encrypted, and it cannot be deleted. This is standard wording for utility apps that monetize through ad SDKs.

Who made it

The developer on the store page is Ameel Haris, based in Jahanian, Khanewal District, Punjab, Pakistan, under the account name Digital Generation Hub. The official site is a calculator page hosted for free on Firebase, and the privacy policy is built on Google Sites.

The same account has more than a dozen utility apps, including a calculator (1.9M installs), an offline music player (950k, launched July 2026), football scores, phone switching, photo recovery, file management, and a universal TV remote. Another account, Attractive Apps Valley, uses the same official site; some of its apps list the contact email [email protected], and it includes a translator with 19.1M installs. So this is a utility studio shipping apps in batches across multiple accounts, and this app is just one new shell on the assembly line.

Where the traffic comes from

The install curve climbed in steps (early on, the numbers are third-party estimates; from Oct 29 onward, they're Google Play installs): around 1K around Aug 17, 65K in Sep 10, 200K in Oct 4, 400K by Oct 21 (+69K that single day), and 651K by Nov 6. Over the last 7 days it added 158K, up about 32% for the week.

There are three visible layers to the playbook.

Riding a famous name and stuffing keywords. The title copies the established app "Number Locator- Call Location," so when users search that term both apps appear together. The description repeats "phone number locator," "call location," "GPS tracker" and "family location" five to ten times each, and the package name com.mobile.number.location.phonenumbertracker is itself a keyword.

Pushing category charts in low-cost markets. In Nov 6 it ranked #13 on the Maps & Navigation Top Free chart in Nigeria, #23 in Italy, #24 in Turkey, and #27 in South Africa and India. Italy climbed from #72 in Oct 29, India from #60, and Malaysia from 107 to 39. It ranks #131 in the US and #150 in the UK (Google Play charts). In these countries the Maps & Navigation bar is very low: tens of thousands of installs can reach the top 30, and once on the chart it picks up some organic traffic.

Most likely buying paid acquisition (inferred). 25 countries charting at once, and an install curve with several single-day spikes of 20,000 to nearly 70,000, don't look like word of mouth. Another number points the same way: 650k installs with only 643 ratings, meaning about one in a thousand users rates it, and recently it adds a dozen to twenty ratings a day. The most likely channel is Google's app promotion ads, or the studio pushing the new app to its existing tens of millions of users through interstitial ads. Neither can be checked from outside, so unverified. Searches on TikTok and X turn up no content about this app.

The ratings look off too. Nov 6 its rating distribution has only one-star (214) and five-star (428) reviews, with every two- to four-star slot at 0. On Oct 31 and Nov 6 the one-star and five-star counts even jump in opposite directions. Same store page: it shows 4.5 stars from Nigeria and 3.7 stars from the US (11-06). In-app prompts for positive reviews, fake reviews, or Google deleting reviews? Unverified.

Where the money comes from

The app has ads, plus a "$16.99 per item" in-app purchase, probably to unlock premium features. A third-party estimate puts the store revenue for this developer account's 4 apps at about $4K a month combined, and this one is below $5K (Peekly estimate). Most of it is probably ads, but ad revenue isn't visible from outside.

The math on this playbook is simple. In Nigeria, India, and South Africa, an install is cheap. Users open the app a few times and see some interstitial ads, and a few pay $16.99. If that covers acquisition cost, keep spending. Weak retention doesn't matter, since it never relied on retention.

Who it's competing with

"Phone number location / phone tracking / family locator" is one of the most crowded utility categories on Google Play, and a dozen-plus others grew faster over the same period.

It's copying others itself, and a string of new shells appeared at the same time: Aug 12's GPS Location Tracker (Family Counsel), Sep 3's GPS Location Phone Tracker (Maps Store, already past 1M), and Sep 25's Phone Number Location Tracker (Sky Vision Apps Lab, already #23 in Nigeria). New knockoffs show up in this category every month.

How many people know it

Very little. No media coverage, nobody on X or TikTok mentions it, revenue isn't public, and only a few chart-tracking data sites pick it up automatically. That doesn't help you much, though: nobody notices it because there are too many apps like it, not because the space is empty. The demand is steady, though. Tutorial videos on TikTok about "how to find someone's location with a phone number" get anywhere from hundreds of thousands to over 4 million views.

If it were you

Verdict: Don't build another "phone number location" shell. The category is packed with copycat knockoffs that rely on misleading titles, and Google is tightening its rules on feature claims and fake reviews for this kind of app. What's worth taking is the distribution process behind it: a need people search for all year, riding the name of an established app and long-tail keywords for search traffic, targeting countries where the category chart is easy to climb, and one studio putting out a dozen-plus utility apps in rotation.

Who it suits: Small teams that already have a utility-app pipeline (templated code, assets, privacy pages), run Google App Campaigns, and can calculate the ad revenue and acquisition cost per user. People who can accept a portfolio release model and don't expect any single app to last long.

Who it doesn't suit: Anyone who wants a product with a good reputation that they can run for years, anyone who hasn't run ads and is counting on organic store traffic, and anyone unwilling to be associated with name-piggybacking or exaggerated titles, which risk takedowns.

How to do it: Start with evergreen search terms and country combinations where the category chart is easy to enter. Map navigation in Nigeria, South Africa, or Turkey, for example, can reach the top 30 with a few tens of thousands of installs. Keep the features honest: a number-range location lookup plus a map tool is useful enough on its own, and clear titles about what the app does reduce clicks but protect the account. If you really want to differentiate on "location," the direction is consent-based family location, but that's the territory of subscription leaders like Life360 and Findmykids. Compete on product, not distribution.

How to acquire users: Spend a small budget buying installs in three or four low-cost countries, and first check whether a user's ad revenue over one week covers the install cost. Catch organic traffic through the category chart and "similar apps" placements. Once you have several apps running, use your own interstitials to send traffic to new apps.

When the window closes: There's no deadline. This is a year-round business. The window depends on when others crowd into the country and category you pick. Map navigation is already crowded in Nigeria and India.

Signs you've misjudged it: ① Over the next month or two it drops off the map charts in these countries and daily installs stop, which means acquisition is outpacing ad revenue and the margins are thinner than they look. ② It, or another app from the same studio, gets removed for misleading claims or fake reviews, which means the risk has eaten the profit. ③ Google tightens review of titles and descriptions for "phone number location" apps, and search traffic for the category dries up.
