Lucky Food: an "AI calorie counter" app gained 120k installs in one week, yet no review mentions calories even once
What it is The store page presents a food-logging tool that estimates calories from photos. Users actually get an app for earning money: watch ads, play mini-games and watch short dramas to collect coins they can cash out.
Why it took off A group is running a batch of "Lucky"-branded shells under multiple developer accounts. They buy paid acquisition and use the promise of "earn money" to pull in waves of users from low-cost markets like Venezuela, Colombia and Bangladesh. The growth comes from ad-revenue incentives, not from any real calorie-tracking demand.
EShould you copy it? No. The only thing worth taking away is a way to spot it: installs rising in steps, ratings climbing at a steady pace, and chart rank not moving. When all three show up together, it's bought traffic, not real demand.

Lucky Food, an "AI photo calorie counter" on Google Play, added 78k installs in a single day in Nov 2. Open the reviews and users are talking about coins, mini-games, short dramas and "when will my money arrive". It's really an earn-money-by-watching-ads app wrapped in a food-logging shell, and paid acquisition has pulled in waves of users from Latin America and South Asia. Here's what it actually is, where the installs come from, where the money comes from, and why you shouldn't follow it.
A one-star review from a Venezuelan user
On Oct 28, under the Mexico store's Play listing, a user left a one-star review in Spanish that got 25 "helpful" votes:
son demasiadas estupideces para de verdad pagar… al menos para Venezuela… cuántas novelas cuantos juegos y ninguno hasta hoy he visto ni un dólar todo es una mentira
It says the app promises money but it's all lies, at least in Venezuela; they've watched so many short dramas and played so many games, and to this day haven't seen a single dollar. It's all a scam.
The review sits under a store page that says: "Lucky Food is a smart AI food-logging app... snap a photo and it recognizes food, estimates calories and nutrients, and gives diet advice based on your body and goals."
The two don't match.
What its numbers look like
Lucky Food launched on Sep 23. The developer is Lucky-Tech Limited, and it's listed under "Tools," not "Health & Fitness." For the first month it barely moved, then it suddenly took off (Google Play installs):
| Date | Total installs | Added that day | Score |
|---|---|---|---|
| 10-29 | 7,909 | — | 67 |
| 10-30 | 7,909 | 0 | 98 |
| 10-31 | 15,167 | +7,258 | 127 |
| 11-01 | 15,167 | 0 | 150 |
| 11-02 | 93,247 | +78,080 | 176 |
| 11-03 | 110,047 | +16,800 | 185 |
| 11-04 ~ 11-05 | 110,047 | 0 | 248 |
| 11-06 | 132,198 | +22,151 | 266 |
Three things are odd.
Installs jump in steps, but ratings climb at a steady pace. Installs go from tens of thousands in a day to zero; ratings rise by a steady 20 to 30 a day and never follow the install spikes. Organic growth doesn't look like this. The shape looks more like a batch of paid traffic that turns on and off. The steady rise in ratings may mean the app is trading in-app coins for good reviews (inferred).
78k installs a day, yet it's almost invisible on the charts. That volume would be enough to crack the top of the Tools free chart in most countries. But across the 30 Google Play countries we track, its best rank was #76 on the Mexico Tools free chart on Nov 4, and by Nov 6 it had slipped to #136. The US, Canada, Spain, Argentina and South Africa all sit 100 places or lower. The volume is coming from other countries; the reviews point to a few: Venezuela, Colombia, Bangladesh, Jamaica (inferred).
The rating ratio is very low, and star ratings differ a lot between countries. 130k installs produced only 266 ratings, about 0.2%. The US store shows 4.3 stars and the Mexico store 4.9 stars, yet most of the "most helpful" reviews in Mexico say the money never arrived.
What users actually get
The top "most helpful" reviews on the Play web page (as seen by 11-06):
- "Lucky food is good for everyone because it's making many things I mean money and many ads showing." (user with a Bangladeshi name, 10-18,57 found it helpful)
- "esta aplicacion trae muy buenos juegos que al princio yo no creia que fuera cierto pero gae mucho dinero" (This app has lots of good games. At first I didn't believe it, but I make a lot of money. Mexico store, 10-19)
- "good morning I hope so too but I'm still waiting for the mood to get my money" (10-29)
- "it's ok but ads are doing my head in" (too many ads, 10-29)
- "muy BN ... pero no he recibido lo q prometen" (pretty good... but I haven't received what they promised; 10-29)
Not one review mentions calories, diet or weight loss. Users talk about games, short dramas, ads and cash-outs. This is an earn-money app: watch ads, play mini-games, watch short dramas to collect coins, then cash out once you have enough. The calorie-counting photo feature is just a front for store review and passers-by.
Behind it is a shell-swapping matrix
Digging into the developer shows a group mass-producing shells:
- The developer account is a bought shell. The contact on Play is listed as a Pakistani person with the email [email protected]. The legal entity LUCKY-TECH LIMITED was registered in the UK in 2021 under the name GETPREZZIE LTD, with the business activity "online retail" (UK Companies House). The same account also hosts several placeholder apps published early on, such as "Pdf jofs" and "Fit Traks," before switching to the Lucky line.
- The developer website has just one line. The homepage of luckymusicapp.org reads "Lucky Music. Play songs to earn coins." The download link pointed to Lucky Music, which is now 404 on Play (checked 11-06). Searching YouTube turns up a few reviews, one titled "Lucky Music Real or Fake. Can make $200 in 30Mins Listening to Music or this is a Scam" (webvator, about 1,100 views). The review says the ads promise $200 for half an hour of listening.
- The same template is spread across several accounts. Package names all start with com.lcm.*, sites are named lucky*music*.org and similar, spread across the Lucky-Tech, JKL Build and JumpSlap accounts. The front faces change: video player, short-drama player, calorie logging.
| App | Developer account | Launched | Installs (11-06) |
|---|---|---|---|
| Lucky Food (this one) | Lucky-Tech Limited | 09-23 | 132k |
| Lucky Video | Lucky-Tech Limited | 08-14 | 134k |
| Lucky Shorts | JKL Build | 09-30 | 60k |
| Lucky Video | CROWN VICTORIA HOTEL | 08-26 | 31k |
| Lucky Food (another one) | Apptualy | 09-10 | 260k |
| LuckyMoney (expense tracking) | Apptualy | 09-09 | 612k |
The last two lines deserve a closer look. Apptualy also has a Lucky Food whose description is nearly word-for-word the same, with the same template package name, launched 13 days earlier and with double the volume. The sibling expense-tracking shell LuckyMoney has South African reviews that read "how to receive the money," "EASY MONEY," "misleading." Whether Apptualy and Lucky-Tech are the same people or one is copying the other can't be seen from the outside.
Where the traffic comes from, where the money goes
Traffic: paid acquisition, marketed as "you can earn money." No ad creatives for this app were captured. But the main app on the same website promises "earn $200 for half an hour of listening," and the staircase shape of the installs basically confirms paid buying (inferred, high confidence). The buying targets markets with cheap CPI and strong demand for "make some extra cash online": Venezuela, Colombia, Bangladesh, the Caribbean. Lucky-Tech doesn't show up in the major ad libraries, which suggests buying through personal or agency accounts. Another possible source is shell migration: users of delisted old shells get redirected to new ones (inferred). No trace turned up on TikTok, creators, media or store search. A tool app with 266 ratings can't bring in 78k people a day through organic search.
Money: rewarded ads. The store page says "contains ads" and lists no in-app purchases. To collect coins, users actively watch rewarded videos, play ad-supported mini-games and watch short dramas, so each user generates far more ad impressions than a typical tool app. The cash-out threshold is set very high. Lucky Music users have complained about "stuck at $31.07" and "progress so slow it takes months," so very little real money actually goes out. As long as the ad revenue per user exceeds the install cost in the low-CPI countries, the math works. The risk of a Play ban is spread across many accounts and constant shell swapping.
Who it's competing with
Its real rivals aren't MyFitnessPal or Cal AI. They're other earn-money shells:
- The Apptualy version of Lucky Food, same name and description (260k installs);
- Digitnesia's Lucky Translate (3.1M) and Lucky Drama (2.24M), focused on Nigeria;
- Trebelle Tours' Luck Dramas and Fun Translate, with websites named *-earn-website;
- AID Japan's LuckyDramas – Watch & Earn, 14.2M installs, whose store page openly says "watch dramas and earn," with no disguise.
From 2026 to October 6, a wave of these "utility shell + make money" apps charted on Google Play. The lane is already packed.
As for the front it borrows, AI photo calorie counting, the legitimate players are big: MyFitnessPal 137M installs, Yazio 58.8M, Foodvisor 12.8M, BitePal 5.52M (7 days +83k), Cal AI 4.57M (Google Play, 11-06). Grey-market apps use "AI calories" as a shell name precisely because the term draws traffic and passes review easily. But that traffic has already been bought at high prices by these subscription products.
If it were you
E, don't touch it. Lucky Food runs on paid acquisition plus shell swapping, and the product itself does nothing. Copy it and you're building an app that makes users feel cheated. Doing it in another country or under another shell name is the same.
Who it suits: No one should copy it. The only thing worth taking away is a detection method, for people who scan charts and data sites every day: installs that jump in steps, ratings that climb at a steady pace, and chart rank that doesn't move. When all three show up together, the growth is almost certainly driven by paid buying or traffic diversion. Filter out that kind of "hit" rather than treating it as a signal of organic demand.
Who it doesn't suit: Anyone wanting to build a "watch ads, earn money" app. It breaks Play's deceptive behavior and ads policies, the main app has already been delisted, and an account ban is only a matter of time. Users in the reviews are already calling it a scam. Those hoping to ride this heat into an AI calorie app shouldn't either: that's a different category, dominated by subscription products like Cal AI and BitePal with eight-figure ad budgets, and it has nothing to do with the 130k installs seen here.
How to build it / how to get users: Not recommended. If what caught your eye is rewarded-ad monetization in low-CPI markets, the legitimate version looks like Mistplay or JustPlay, whose store pages plainly say "play games, earn rewards," with rewards paid out on schedule (scale not verified here). That's a different business, requiring game publishing and anti-fraud capability, and has nothing to do with this shell.
Where this could be wrong: ① Over the next three months, the Lucky Food listing and the same-named Apptualy app both stay live, installs keep rising, and reviews fill with screenshots of money received, which would mean the operators really are paying out and the model is more legitimate than it looks; ② Play keeps not acting against this type of "tool shell + earn money" app, and volume at Digitnesia, AID Japan and similar apps keeps climbing, meaning the window lasts longer than estimated. Even then, it remains a business built on buying traffic and accounts, not an opportunity for an independent developer.

- Inferred Paid ads, creatives pitching "earn by listening / playing games": the main app on the same site, Lucky Music, per a YouTube review, promises "$200 for half an hour of listening" (2026-05-03). This app's installs jump in batches.
- Inferred Traffic diverted to low-CPI countries we don't track (Venezuela, Colombia, Bangladesh, Jamaica, etc.): the countries and names in the reviews. Single-day gains of +78k installs, yet the peak among the 30 tracked stores was only #76 on Mexico's Tools chart.
- Inferred cross-promotion inside a matrix / shell-swap migration: the main app com.luckymusic.player.audio.mp3player is already on Play 404; the same team keeps launching new shells; the games and short dramas mentioned in reviews are content shared across the B-side apps
- Inferred Incentivized good reviews: ratings climb steadily, out of sync with the install spikes. Mexico shows 4.9 stars, but most of the "most helpful" reviews say the money never arrived.
- Inferred TikTok / creators / media / organic search: TikHub and web search found nothing relevant; meta / tiktok / google ad libraries show nothing either (this kind of paid acquisition often runs through personal or agency accounts)

Channel: Google Play | Developer: Lucky-Tech Limited | Store launch 2026-09-23 | Research day 2026-11-06
Bottom line
It isn't really an app that does "AI photo calorie counting." The store page is an AI food-logging tool (side A), but what users actually get is an earn-money app: watch ads, play mini-games, or watch short dramas to collect coins for cash-out (side B). It's a new shell in a "Lucky" family of earn-money app decoys. Paid acquisition sells the promise "earn money by listening to music or playing games" to users in markets like Mexico, Venezuela, Colombia, Bangladesh and the Caribbean, and revenue comes from in-app ads (the store page says "contains ads" and lists no in-app purchases). The installs come from batches of paid campaigns, not from calorie tracking as a category.
1. How to read the data
| Date | Total installs (exact Play figure) | Added that day | Score | Source |
|---|---|---|---|---|
| 10-22 | 4,654 | — | — | AppstoreSpy estimate (app_day_ext) |
| 10-27 | 7,906 | — | — | Same as above |
| 10-29 | 7,909 | ≈0 | 67 | googleplay library app_snap |
| 10-31 | 15,167 | +7,258 | 127 | Same as above |
| 11-02 | 93,247 | +78,080 | 176 | Same as above |
| 11-03 | 110,047 | +16,800 | 185 | Same as above |
| 11-06 | 132,198 | +22,151 (3 days total) | 266 | Same as above |
A few things look off:
- Installs rise in steps, but ratings climb at a steady pace: total installs 10-28/29 barely moved (+2), while 11-02 jumped +78k in a single day; over the same period ratings rose steadily by 20~36 per day. That pattern means a batch of paid or channel traffic came in and stopped, not organic growth.
- Installs went up but chart rank didn't move: +78k installs in one day should land it in the top few TOOLS charts in whichever country it's getting them, yet among the 30 storefronts we track its best is #76 on the Mexico TOOLS Top Free chart (11-04), with the rest at #100~190 on TOOLS charts in Argentina, South Africa, the US, Canada and Spain (googleplay library chart_rank). So most volume comes from countries we don't track. The reviews show where: Venezuela ("at least for Venezuela..."), Colombia, Bangladesh, Jamaica (see below).
- Ratings count / installs ≈ 0.2%. Star ratings vary a lot by store: US 4.3, Mexico 4.9 (Play web page, 11-06).
- Version has stayed at 1.0.1 (10-14 updates), with no in-app purchases and ads (app_snap.offers_iap=False, ad_supported=True).
2. What it actually is: side A a calorie tool, side B an earn-money app
Store page (side A): "photo-based food recognition, estimates of calories and nutrition, diet suggestions," but filed under TOOLS rather than health & fitness. Decoy packages commonly do this: tool category gets easier approval and less competition.
What users say (side B), from the top-voted reviews on the Play page (2026-11-06 scraped):
- "Lucky food is good for everyone because it's making many things I mean money and many ads showing." (Md Masud Rana, 10-18,57 people found it helpful)
- "good morning I hope so too but I'm still waiting for the mood to get my money 🤑." (Everton Warren, 10-29)
- "it's ok but ads are doing my head in" (10-29)
- Mexico store: "esta aplicacion trae muy buenos juegos que al princio yo no creia que fuera cierto pero gae mucho dinero" (This app has lots of good games; at first I didn't believe it, but I earned a lot of money; 10-19,26 people found it helpful)
- "son demasiadas estupideces para de verdad pagar… al menos para Venezuela… cuántas novelas cuantos juegos y ninguno hasta hoy he visto ni un dólar todo es una mentira" (So many short dramas and games, and I haven't seen a single dollar; it's all a lie; 10-28,25 people found it helpful)
- "muy BN ... pero no he recibido lo q prometen" (Very good... but I haven't received what they promised; 10-29)
Not one review mentions calories or diet. The reviews talk about "games," "short dramas (novelas)," "ads," and "withdrawals." This is an earn-money app: watch ads, play games, watch short dramas to stack coins.
Developer identity (Play page "About the developer" + UK Companies House):
- The Play contact is Zayyad Zaheer, Pakistan, [email protected];
- The legal developer entity is LUCKY-TECH LIMITED (UK Companies House 13486581), 2021-06 registered in Solihull, formerly GETPREZZIE LTD, with the stated business "online retail." A renamed UK shell company used to hold a Play developer account is a common sign of account buying or renting;
- The same developer account also has "Pdf jofs," "Fit Traks" (package com.rhinos.provider, matching the rhinoscab email) and "WT Willer" (com.togafrica.tcpature), which look like throwaway placeholder apps from early on, later swapped for Lucky-family apps (Play developer page);
- The developer website luckymusicapp.org homepage has one line: "Lucky Music. Play songs to earn coins." The download link points to com.luckymusic.player.audio.mp3player, and that app is already 404 on Play (checked 2026-11-06).
3. The matrix it belongs to
Google Play apps with the same template and similar domain names (installs and 7-day new adds are library counts of 11-06):
| App | Developer account | Launched | Installs | 7 new in the last day | Website domain |
|---|---|---|---|---|---|
| Lucky Food (this app) | Lucky-Tech Limited | 09-23 | 132k | 124k | luckymusicapp.org |

| Lucky Shorts | Apptualy | 09-11 | 77k | — | luckbudgettrack.org |
- The com.lcm.* package prefix ("lcm" = Lucky Music?) is shared across three developer accounts: Lucky-Tech, JKL Build and JumpSlap. The websites are all lucky*music*.org-style. One team spreads shells across multiple developer accounts, and the shells just get reskinned: video player, music player, calorie logger, budget tracker.
- Apptualy's Lucky Food and this app have almost word-for-word identical descriptions, with the same package template (luckyfood.eating.calorie.*). It went live 13 days earlier and is twice the size. Either it's another account from the same group or it's a copy of the original; either way it's the closest "same product" to this one. Reviews of Apptualy's LuckyMoney (a budgeting shell, googleplay library reviews, South Africa) are all "how to receive the money," "EASY MONEY," "misleading," "keeps asking me to pay": the same earn-money side B.
- The larger ecosystem of similar apps: Digitnesia's Lucky Translate (3.1M installs, site lt-earn-website.fast-drama.com), Lucky Drama – Shorts & Rewards (2.24M), Rich Downloader – lucky & earn; Trebelle Tours' Luck Dramas / Fun Translate / Hot Translate / Lucky Downloader (sites all *-earn-website.luckyrewardtool.com). All are "tool shell + earn-money side B" apps, launched in dense waves through 2026 6~October, targeting Nigeria, South Africa and Latin America.
- ScamAdviser's list of new sites includes subdomains like fdp2-mob.luckbudgettrack.org, which look like landing pages for the in-app H5 (side B).
4. Where users come from
| Channel | Evidence | Confidence |
|---|---|---|
| Paid ads ("listen to music / play games to earn money" creatives) | The main app on the same site, Lucky Music: a YouTube review says "The app in Advert claims you can earn money quickly by simply listening to songs" and "earn up to $200 in just 30 minutes" (webvator / Apex Verdict, 2026-05-03). Installs jump in batches, unlike organic growth. | Confirmed at the matrix level; this app's specific creatives weren't captured |
| The volume comes from countries we don't track (Venezuela, Colombia, Bangladesh, Jamaica, etc.) | Countries and names from reviews; +78k installs in a single day, with the best rank among the 30 tracked storefronts being #76 on Mexico TOOLS | Inferred |
| Cross-promotion within the matrix / migrating users from shut-down shells to new ones | The main app com.luckymusic.player.audio.mp3player is already 404; new shells keep launching (10-14, 10-15 are still being added); reviews say "this app has lots of games and lots of short dramas," matching the side B content of the other shells | Inferred |
| Prompted reviews | Ratings climb steadily while installs jump, so the two don't line up; Mexico store 4.9 stars, but the most helpful reviews mostly say "never received the money"; reviews include lines like "buy my family a house" and "EASY MONEY" (LuckyMoney) | Inferred; possibly in-app coins given in exchange for good reviews |
| Store search / ASO | A tool app with 266 ratings and a chart rank beyond #100 can't get 78k installs in a day from organic search | Largely ruled out |
| TikTok / creators / media / X / Reddit | TikHub searches for "lucky food app" and "lucky food dinero" found no relevant videos; web search only turned up APK sites and data sites | None found |
| Our ad library | metaads, tiktokads (Europe only) and googleads show nothing for Lucky-Tech or this app. Apptualy's Lucky Food is in the list, but Google searches for the legal entity name, product name and domain show no advertiser (11-02), and TikTok lists it as "unconfirmed" | No results doesn't mean no spend: this kind of advertising runs through personal or agency accounts, and the ads aren't in the countries we track |
Where the money comes back: free, no in-app purchases, ad-supported. Users, chasing coins for cash-out, watch rewarded videos and play ad-filled mini-games and short dramas on their own, so ad impressions per user far exceed those of a typical tool app. The cash-out threshold is set very high (Lucky Music users: "stuck on $31.07," "progress is extremely slow, it takes months"), so little money actually gets paid out. As long as ad revenue exceeds the per-install acquisition cost (CPIs are very low in these countries), the business works. Play ban risk is spread across many accounts and constant swapping of shells.
5. Competitors
Competitors in its real business (earn-money apps):
- Apptualy's Lucky Food: same name, same description, 260k installs, 13 days earlier;
- Other shells from the same team: Lucky Video / Lucky Shorts / LuckyMoney, etc.;
- Digitnesia (Lucky Translate 3.1M, Lucky Drama 2.24M), Trebelle Tours (Luck Dramas 250k etc.), AID Japan's LuckyDramas – Watch & Earn (14.2M);
- Legit Western "watch ads / play games to earn" apps (Mistplay, JustPlay, etc.; scale not verified in this check).
Legitimate apps with the same name as its store positioning (AI photo calorie counting) (Google Play library, 11-06): MyFitnessPal (137M installs), Yazio (58.8M), Foodvisor (12.8M), BitePal (5.52M, 7 days +83k), Cal AI (4.57M), CaloVision (620k, 2026-06 up). They make money from subscriptions and have no real competition with this app, but it borrows the heat of the "AI photo calorie counting" category to name its shell and get past review.
6. Differentiation
The product itself has no differentiation. Calorie tracking is just a review-passing shell. Users never see its "AI recognition" on the store page; they're pulled in by ads promising they can make money. If there's anything different, it's operational:
- Pick a category: choose a "legitimate tool" shell that has been hot for 2026 years, is easy to get approved, and sits under TOOLS.
- Multi-account shells: the same B-side is attached to multiple shells across accounts like Lucky-Tech, JKL Build, JumpSlap, and Apptualy. If one gets banned, another takes over.
- Paid acquisition targets countries with very low CPI and high demand for "make money online" (Latin America, South Asia, Africa, the Caribbean), which our charts barely cover.
It ran up the charts because of this distribution and shell-swapping playbook. The product itself isn't the reason.
7. Visibility and copycats
- Visibility: no media, X, or TrustMRR coverage. Only APK sites and data sites (AppBrain, APKPure, Similarweb, chrome-stats) have auto-indexed it. Lucky Music, in the same matrix, has a few "is this real?" reviews on YouTube (roughly 1,000 views each). Almost nobody knows about it yet, and those who do treat it as a suspected scam.
- Copycats: this model is already crowded (Digitnesia, Trebelle Tours, AID Japan and others are doing it). Apptualy had an identical "Lucky Food" name and description 13 days earlier.
8. What to borrow
- How the "tool shell + incentivized-ad B-side" makes money: in markets where traffic is cheap, "watch ads to earn coins" can push ad impressions per user high enough that ARPU covers CPI. But this violates Play's deceptive-behavior and ads policies, with high risk of account bans and delistings (the main app is already 404), so don't copy it.
- What's worth borrowing from legitimate practice: use the mismatch between the install curve (stepped jumps), the rating curve (steady), and chart rank to identify apps driven by paid or referral acquisition, and remove them from the candidates for "organic breakouts."
- At the opportunity level: by 2026, "AI calories" was hot enough that gray-market players were using it as a shell name. That shows the category has big traffic and is review-friendly, but there are many legitimate players (Cal AI, BitePal, Foodvisor and others are all spending heavily on ads).
9. Still unclear
- The specific form of the B-side (H5 or native, and whether a remote switch turns it on only for paid-acquisition users) hasn't been verified on a device.
- No specific acquisition channels (Facebook / TikTok / Google UAC / offerwalls) or creatives were found. There's only indirect evidence from Lucky Music in the same matrix, whose ads claim you can earn money by listening to music.
- It can't be determined whether Lucky-Tech and Apptualy are the same team or copying each other.
- The real country distribution (reviews are only inference), and whether anyone has actually cashed out.
