A page with 16 likes that bought "free download" ads in 10 languages in one day: how the caller ID app Callora bought 75k installs
What it is An Android caller ID and spam-blocking app with no phone number database of its own. It makes money from ads and in-app purchases, and its features match dozens of similar apps.
Why it took off The publisher is effectively a paid-acquisition agency. Oct 30, it ran ads in a dozen-plus minor languages aimed at cheap-install emerging markets. Similar apps from the same page, CallFilter and Peekora, had already shown the category pays back.
CWhat you can do with it Don't build another caller ID wrapper. A team with paid-acquisition skills should learn to validate a category on other people's apps first, then build its own, or target local scam scenarios that big incumbents cover poorly, backed by real data.
- Data (updated daily) · first launch 2026-10-21 · 11-07 installs 75,086
Android · Total installs worldwide Data 2026-10-29 → 2026-11-07 (10 days, 10 observations). Google's detail page only refreshes install counts every other day, so a flat day doesn't mean nobody installed.
Callora, a caller ID app launched Oct 21, had 29 installs in Oct, 831 in Nov 6... and 75,086 installs by Nov, with not a single rating. It has no phone number database of its own, and its features match dozens of similar apps. It got traction because Appevo, the company that publishes it, already runs ads for other clients, so the accounts and creative pipeline were ready. Below: how the volume was bought, where the money comes from, who the competitors are, and whether you should follow.
The Oct 30 ad wave
In Oct 30, a Facebook page called "Browser AI Tv" with only 16 likes ran a dozen-plus video ads in a single day. Every landing page led to Callora's Google Play listing. The name has nothing to do with caller ID. Each ad had one line of copy, translated into Armenian, Amharic, Sinhala, Odia, Swahili, Kannada, Uzbek, Turkish, Vietnamese and Spanish: "Pakua Bure!", "Ücretsiz İndir!", "Tải xuống miễn phí!", all meaning "free download!". The body text said "Try it for free right now!!" The next day Hindi, Bengali and Arabic versions followed.
The earlier ads ran Oct 23 to 26 in English, French and Arabic, with body text like "Avez-vous déjà testé cette fonctionnalité ?" (Have you tried this feature yet?). None of them said what the app does. Placements were Facebook, Instagram, Threads and Audience Network (Meta Ad Library, 11-05).
By Nov 5, ads leading to Callora totaled 31, with 28 still running. The same page has run 533 ads in total. As of Nov 4, 56 were live, and the most recent check showed 70.
How the volume built up
| Date | Cumulative installs (Google Play) | Countries charted | Best rank (Communication, free chart) |
|---|---|---|---|
| 10-29 | 831 | 5 | Turkey 125 |
| 10-31 | 4,315 | 8 | Turkey 80 |
| 11-03 | 51,138 | 20 | Vietnam 58 |
| 11-06 | 75,086 | 25 | South Africa 16 |
Google Play install counts refresh only every few days, so the "+47k" on 11-03 accumulated over several days rather than spiking on one day. Third-party estimates (AppstoreSpy, AppInsider) put installs at 8k to 12k per day from Oct 30 onward. The inflection point lines up with the Oct 30 minor-language ad wave, and the countries that charted match the ad languages: South Africa 16, Nigeria 21, Indonesia 24, Turkey 27, UAE 28, Malaysia 34, India 36, Saudi Arabia 39, Vietnam 41. Its rank in the US, Europe and other Western markets was 76 or lower, and it never charted in the overall or Top Grossing lists.
75k installs, 0 ratings, 0 reviews. If real people were using it, some would leave star ratings. Zero suggests the installs were bought, and it also hasn't prompted users to rate it. Searching the web turns up nothing about it: no press coverage, TikTok searches for "Callora" return an unrelated couples app and a clothing shop, and nobody on X has mentioned it in nearly 30 days. The only hits are auto-generated pages on download sites like AppBrain and Softonic.
The publisher already runs ads for others
Appevo's website describes itself as "Mobile App Publishing & Growth" and lists paid acquisition, creative testing and budget management as services. Its terms of service are more direct: Appevo "also provides advertising services, including managed advertising accounts and campaign management for apps and games" across Google, Meta and TikTok (appevo.us/terms, 11-06). Its registered address is Suite 305 in Newark, Delaware, which looks like a registered-agent address (unverified).
In other words, its main business is managing and buying ads for other people, and it also publishes a few apps on the side. The proof is in the 16-like page: "Browser AI Tv" was running ads for 5 other developers' apps at the same time.
| Apps it advertised | Developer | Total installs | New in the last 7 days |
|---|---|---|---|
| Callora: Caller ID & Block | Appevo | 75k | +74k |
| CallFilter: Caller ID & Block | AppSense Digital | 2.42M | +496k |
| Peekora: ID Caller, Block Spam | Kaizo Innovation | 5.59M | +297k |
| Metopia-Random Video Chat Live | Black King Bar | 1.8M | +128k |
| Zodiakos: AI Astro Birth Chart | Falcons Mobile App | 570k | +102k |
(Install counts are for Google Play, 11-06.)
The developer contact emails for these apps are mostly Gmail addresses with Vietnamese names. From the outside, there's no way to tell whether Appevo and these developers are one team or a vendor-client relationship (inference: at least a very close partnership).
The most telling part of the table is that the same page was advertising two caller ID competitors at once. CallFilter launched in May and still grows 500k a week. Peekora also launched in May and has reached 5.59M. This category has already proven it pays back in this ad system. Callora is the same playbook run again on a new app of its own. Another app from the same publisher, DuoSpace (a dual-account tool) launched Oct 16 and shows nearly the same curve: 10-31, 4,799,11-05, 51,332. The publisher also has a few generic utilities for QR scanning, bookkeeping and screen casting. Whatever works gets more budget.
What it sells, and where the money comes from
The store listing names four features: caller ID, blocking blacklisted numbers, number lookup and contact matching. Each one comes with a disclaimer, such as "when supported information is available", "Not every phone number will have identifiable information" and "No caller identification or spam detection system can guarantee…". It never claims to have a number database. That kind of wording is mostly there to pass app review, not to convince users.
Revenue comes from ads and in-app purchases, priced at $3.99 to $24.99 each. The business logic of caller ID is simple: every call triggers a caller-ID popup or a post-call screen, and people get calls every day. So each user sees several ads a day, and the app then sells an ad-removal or "premium blocking" subscription. The main markets are South Africa, Nigeria, Indonesia and the Gulf, where installs are cheap, and Audience Network inventory is cheaper still. How much Callora has earned and how well it retains users isn't visible from outside. But the same page keeps increasing spend on CallFilter, so the category is likely profitable (inference).
Who it's competing with
| Product | Launched | Scale | How Callora differs |
|---|---|---|---|
| Truecaller | 2012 | 1.9B installs | Has a crowdsourced number database and brand recognition; charts in several countries' Top Grossing lists |
| CallApp / Eyecon / Whoscall / Hiya | 2010–2016 | 18M to 430M installs | Established, with a database and subscriptions |
| Trust Call(Maxify Global)/ Caller ID: Trusted Call(Appsquad) | 2026 | 13.2M / 17.2M | The earliest to prove the template in this system. Callora's titles copy its structure |
| Peekora / CallFilter | 2026-05 | 5.59M / 2.42M | The same page is advertising it. Its volume is 30 to 70 times Callora's |
| Call Blocker: Caller ID, SMS(Nonari Tec) | 2026-09 | 540k, +470k in 7 days | A contemporary clone that spent more aggressively |
| Callog, TrustCall and others | 2026-07 to 10 | 70k to 220k | Similar clones from the same wave |
| Google Phone / Samsung Smart Call | Built into the system | Preinstalled | Free, with built-in spam call warnings |
Even the name isn't unique. An earlier caller ID app called "Callora: Caller ID & Lookup" exists, using the same package prefix, com.callora.callerid, and another app with that prefix has since been pulled from the store. A design asset site, UI8, sells a "Callora - Smart Caller Protection App UI Kit". Several of these likely share the same UI template or even the same source code (unverified). At least 25 new caller ID apps launched after June 2026 and are still growing.
Callora isn't the one being copied. It's the one copying.
If it were you
Grade C. Learn from Appevo's method, not the caller ID product. Building another caller ID wrapper doesn't pay: over twenty new clones are competing for the same users, the leaders have dozens of times its volume, and they share a single agency that pays less for ads than you do.
Good fit for: small teams with Meta or Google paid-acquisition experience, a reliable ad budget, and the math to know how many days it takes an install to pay back through ads; or anyone who already works as an ad-buying agency.
Not a fit for: people who haven't run ads and hope to get organic traffic from store search or content (this app had 75k installs and 0 ratings, which means nobody found it on their own); and anyone who wants to build a "better caller ID" to compete head-on with Truecaller. Its number database took over a decade of users to build, and you won't have one.
How to do it: If you have paid-acquisition skills, the thing worth copying is "validate the category on other people's apps first, then build your own." Look in the Meta Ad Library for low-like pages that keep scaling spend on utility apps. If one category has been run by the same page for months and keeps getting more budget, that's a sign it pays back. Then build a same-category app on a ready-made template, launch quickly, and focus effort on the ad slots on the post-call screen and the subscription page. If you want to build caller ID itself, the only meaningful angle is where incumbents are weak: scam numbers specific to one country, or spam texts in a particular local language. Only real data creates retention.
How to acquire users: Copy its creative. Translate a single "free download" line into a dozen minor languages, use vertical video, and run it on Facebook and Instagram plus Audience Network. Start in South Africa, the Gulf, and Southeast Asia, where installs are cheap and the category-chart bar is low. In South Africa, around 10k installs a day was enough to reach the top 20 in Communication. Once charted, it picks up some organic exposure too.
Deadline: There's no obvious cutoff. The category has been crowded for half a year and gets more so every month. If you want to test it, run one round on a small budget within a month. If it doesn't pay back, stop.
Signs this analysis got it wrong: (1) After late November, Callora keeps installs above ten thousand a day, starts getting ratings, and charts in any country's Top Grossing list. That would mean users stay and pay, and the category is broader than it looks. (2) Conversely, if Browser AI Tv cuts its ad spend on CallFilter and Peekora by more than half in December, even the category leaders aren't paying off. (3) If Google Play tightens permissions for call logs and contacts, or clears out duplicate caller ID apps, this whole batch of clones drops together.

Callora: Caller ID & Block (Appevo, LLC): why it took off
Google Play package com.callora.callerid.spam.blocker.phone.lookup, COMMUNICATION category, first listed in the store 2026-10-21, version 1.0.1 (updated once on 11-03). Research date 2026-11-06.
Bottom line
This is a "caller ID + blocklist" template shell with no proprietary number database. It took off not because of the product, but because the publisher, Appevo, is itself a paid acquisition agency: starting 10-23, it ran ads on Meta through a "managed" page with only 16 likes that was also running ads for 5 other developers, pouring spend into emerging markets with free-download videos in a dozen-plus languages. Once the spend ramped up, installs went from a few hundred a day to 8.5 to 12k a day, and the countries it charted in grew from 5 to 25 within a week. There's essentially no differentiation, and that isn't what drove the growth.
1. Data: how it grew
googleplay library, app_snap / app_day / chart_rank; the estimates in app_day_ext are from AppstoreSpy:
| Date | Cumulative installs (store) | AppstoreSpy estimated daily gain | Countries charted | Best category rank |
|---|---|---|---|---|
| 10-29 | 831 | 4 | 5(tr/ae/sa/id/vn) | tr 125 |
| 10-31 | 4,315 | 8,569 | 8 | tr 80 |
| 11-01 | — | 8,569 | 16 | id 66 |
| 11-03 | 51,138 | 8,569 | 20 | vn 58 |
| 11-04 | — | 12,548 | 23 | za 34 |
| 11-06 | 75,086 | 11,974 | 25 | za 16 |
- On 11-06, every ranking was in the COMMUNICATION Top Free chart: South Africa 16, Nigeria 21, Indonesia 24, Turkey 27, UAE 28, Malaysia 34, India 36, Saudi Arabia 39, Vietnam 41, Brazil 44, Argentina 45; Europe and North America (de/gb/fr/ca/au/es/it) sat between 76 and 139. It never charted on the overall or Top Grossing charts.
- 0 ratings, 0 reviews (0 rows in the review table). 75k installs and not a single review: the typical look of pure paid-acquisition users, who install without leaving a trace and with no prompt for a good rating.
- Monetization runs in-app purchases and ads in parallel: iap_range $3.99–$24.99, ad_supported = True.
- Store install counts refresh only every few days, so the "+47k" on 11-03 is actually the total over 10-31 to 11-03 days, not a single-day spike. In reality, after 10-30 it held steady at 8 to 12 thousand a day, a "floodgate" platform curve.
- The same publisher's DuoSpace: Dual Apps (listed 10-16) has an almost identical curve: 10-31 ran from 4,799,11-05 to 51,332, with AppstoreSpy estimating 6 to 15 thousand daily gains. This shows Appevo runs several titles at once.
- Third-party figures: AppInsider estimates "10k+ downloads per day", with a timeline of listing on 10-21, first discovery on 10-29, entering new countries on 11-04, and reaching the top 2 of 100 charts (appinsider.io). I have not verified the Appfigures figure of about 124k cumulative for November cited on the recall card.
2. Growth tactics: the evidence chain
2.1 Meta paid acquisition (confirmed)
The ad and app_link tables in the metaads library show 31 ads landing on this package, 28 of them still running:
- The ad page is called "Browser AI Tv" (page_id 102289815491031), with 16 likes, 533 ads cumulative in history, 11-04 running 56 now, 11-07 with 70 running. It has appeared in the first screen for the keyword "ai girlfriend".
- Ad cadence:
- 10-23 started the first batch (English and French, "Try it for free now").
- From 10-30 to 10-31 it pushed about 19 ads at once, in languages including Arabic, Hindi, Bengali, Kannada, Odia, Sinhala, Swahili, Amharic, Uzbek, Armenian, Turkish, Vietnamese and Spanish.
- From 11-02 to 11-05 a few more were added.
- All creatives are video, and the copy is just "Free download / Try it free now", with no functional selling points. Placements are Facebook, Instagram, Audience Network and Threads.
- This matches the install curve: when 10-23 first ran ads it was still testing (only 10-29 installs at 831); when the large multilingual batch went live on 10-30, AppstoreSpy's estimated daily gain jumped from 4 to 3,484 that same day, then stabilized above 8.5 thousand. The charting countries also line up with the creative languages: South Africa and Nigeria (English and Swahili directions), the Gulf (Arabic), Turkey, Vietnam, India, and Latin America.
2.2 The publisher is itself an ad-buying agency (confirmed)
- The appevo.us homepage reads "Mobile App Publishing & Growth", with services covering paid acquisition, creative testing and budget management (appevo.us).
- The terms of service state: "Appevo, LLC also provides advertising services, including managed advertising accounts and campaign management for apps and games. Campaigns may run on Google Ads, Meta Ads, and TikTok Ads" (appevo.us/terms). In other words, its core business is renting out or managing ad accounts and running campaigns, and it also publishes apps on the side.
- The address is 131 Continental Dr, Suite 305, Newark, DE, a Delaware LLC. The address looks like a registered-agent or virtual office, unverified.
- The "Browser AI Tv" page is also running ads for 5 different developers' apps (metaads app_link):
| Apps it advertised | Developer | Installs (googleplay library) | 7-day gain |
|---|---|---|---|
| Callora: Caller ID & Block | Appevo, LLC | 75k | +74k |
| CallFilter: Caller ID & Block | AppSense Digital (email [email protected]) | 2.42M | +496k |
| Peekora: ID Caller, Block Spam | Kaizo Innovation (email [email protected]) | 5.59M | +297k |
| Metopia-Random Video Chat Live | Black King Bar | 1.8M | +128k |
| Zodiakos: AI Astro Birth Chart | Falcons Mobile App | 565k | +102k |
| A private browser / video downloader | — | — | — |
These 5 developers' emails are mostly gmail addresses with Vietnamese names. A low-follower page pushing several developers' apps fits the model of an agency renting out ad accounts. I infer Appevo's team is the same as, or partners with, this Vietnamese ad network, unverified.
- Interestingly, the same managed page is running ads for two direct competitors (CallFilter, Peekora). CallFilter launched in May, already has 2.4M installs, and is still growing at about 500k a week. This suggests the "caller ID" category has already been shown to pay back within this network, and Callora is rerunning a proven playbook on a new package.
2.3 Store search and ASO (confirmed, secondary role)
- The title "Caller ID & Block" directly copies the title structure of "CallApp: Caller ID & Block" and Maxify Global's "Trust Call: Caller ID & Block". The package name is packed with the words callerid / spam / blocker / phone / lookup.
- The description is all compliance-style vague language ("when supported information is available", "No caller identification … can guarantee"), mainly to pass review rather than to convert.
2.4 Content, creators, media (none)
- The 20 TikTok results for "Callora" (via TikHub) are same-named couple apps, clothing shops and the like, unrelated to it.
- X (x-radar, searching "Callora" and "Appevo" over 30 days): 0 posts.
- The web only has auto-aggregator sites like AppBrain, AppInsider and Softonic. No media coverage and no founder posting revenue.
2.5 Platform events (possibly related, not proven)
Another report in the same batch (Trust Call / Amobear) mentions that India's CNAP (carrier-verified caller name display) became mandatory starting 2026-11-01, which may have pushed up search interest in "caller ID". But Callora's main markets are South Africa, Nigeria, Indonesia, Turkey and the Gulf, with India only ranking #36, so CNAP is a weak explanation for its growth.
3. Competitors
| Competitors | Channel | Launched | Scale | How Callora differs |
|---|---|---|---|---|
| Truecaller | Android / iOS | 2009–2012 | 1.91B installs (googleplay library) | Has a crowdsourced number database and a brand, and charts on Top Grossing in multiple countries; Callora has no number data of its own |
| CallApp / Eyecon / Whoscall / Hiya | Android | 2010–2016 | 18M to 434M installs | Established, with a database and subscription system |
| CallFilter: Caller ID & Block(AppSense Digital) | Android | 2026-05-13 | 2.42M, 7 days +496k | The same managed page is running ads with the same playbook, at 30 times the volume |
| Peekora: ID Caller, Block Spam(Kaizo Innovation) | Android | 2026-05-07 | 5.59M, 7 days +297k | The same managed page is running ads |
| Call Blocker: Caller ID, SMS(Nonari Tec) | Android | 2026-09-11 | 543k, +472k in 7 days, #7 in India Communication | A contemporary template clone with heavier ad spend |
| TrustCall (A CUBED) / Trust Call (SHI & COMPANY, Amobear network) / Callog (Great Leaps) | Android | 2026-07 to 10 | 70k to 220k | Same batch of clones, already covered in this library |
| Trust Call: Caller ID & Block(Maxify Global)/ Caller ID: Trusted Call & SMS(Appsquad) | Android | 2026 (store date, may have been reset) | 13.2M / 17.2M | An early winner from this template |
| Callora: Caller ID & Lookup(Murchary Application,com.callora.callerid.numberlookup) | Android | about 2026-09 (date of the page Exa captured) | Not verified | Earlier, it used the same name and the same com.callora.callerid package prefix; another, com.callora.callerid.spamcallblocker, has since disappeared from the store |
| Google Phone / Samsung Smart Call | Big-company features | Years | Preinstalled | Free, with built-in harassment warnings |
UI8 also sells a paid interface template called "Callora - Smart Caller Protection App UI Kit" (ui8.net). Several apps are named Callora with the same package prefix, so they probably share the same UI template or source code. Not verified.
4. Why it works (in order of importance)
- It is itself an ad-buying agency, with acquisition costs and accounts in-house. Its terms of service say it manages ad accounts. One Facebook page with 16 likes promotes 5 developers at once. After that batch of 10-30 multilingual creatives went live, 19 installs jumped from a few hundred a day to over 8 thousand.
- The category has already been proven profitable on the same network. The same page is also running CallFilter and Peekora, which have 2.42M and 5.59M installs respectively, and both are still climbing by hundreds of thousands a week. Caller ID users are cheap in emerging markets, and revenue comes from Audience Network and AdMob ads, plus $3.99–$24.99 subscriptions.
- It targets low-CPI countries and pushes for the category chart. These countries have low bars for the COMMUNICATION free chart. At around 10k daily installs it can reach the top 20 in South Africa, and once charted it gets some organic exposure too.
- Test several packages in parallel. DuoSpace's curve is almost identical. The publisher also has ScanPro, Tabmate and Tvmate, all general-purpose tools. If one category or package doesn't work, they switch to the next.
5. Differentiation
Almost nothing. The features are a local blocklist, contact matching and number lookup. The description itself admits "Not every phone number will have identifiable information". The name isn't unique either: there are at least two other Callora caller ID packages. The real edge is on the publishing side: it pays no agency fee, and the ad accounts are its own. That's why it can test cheaply, but for users the product has no noticeable difference.
6. How many people know it / has anyone copied it
- Almost nobody knows about it yet: no press coverage, 0 posts on X and TikTok, no disclosed revenue, only automated directories like AppBrain and AppInsider.
- But the category itself is already crowded: in this library, more than 25 new caller ID apps listed after 2026-06 are growing. So Callora isn't being copied; it's one of the followers.
7. Takeaways
- The model is "ad agency and publisher in one": with ad accounts and a creative pipeline, you can use the same page to test categories for several clients and your own apps in turn. Whichever category works (like CallFilter) gets a copy of your own app right away.
- The creatives barely mention features. "Free download" is translated into a dozen minor languages and aimed at South Africa, Nigeria, the Gulf and Southeast Asia, paired with Audience Network. This keeps CPI very low and gets to the category chart fast.
- The question is whether the money comes back. A 0 rating plus pure paid acquisition means retention and subscription rates are unknown. Since the same network keeps adding budget to CallFilter, this category is probably positive ROI.
8. Uncertain
- No data on ROI, retention or subscription conversion. We haven't seen its ranking on the grossing chart.
- Whether Google Ads and TikTok ads were used: this package isn't in the googleads library, and tiktokads only covers Europe, so absence there doesn't mean no spend.
- Whether Appevo and the Vietnamese developers (Kaizo, AppSense, Black King Bar) are the same team or an agency-client relationship can't be confirmed.
- The relationship between the several packages named Callora, and whether they share UI8 templates or source code, has not been verified.
- The Appfigures 124k and the Similarweb Bulgaria #48 mentioned in the recall card are unverified.
