Boothie is a phone app that changes the look of a selfie. The user picks a look and takes or uploads a photo, and the app returns the same person as if a different camera had taken the picture. The best-known look is the digicam look. Digicam is short for digital camera; online, the word means the style of a cheap compact camera from the 2000s: a hard direct flash, strong colours and some grain. Boothie does not compute the new picture itself. Its privacy policy says that the app sends the photo to Gemini, an image model from Google, which is an AI model that takes a picture and a written instruction and produces a new picture. A free editor with film filters runs on the phone without AI. An AI picture costs credits, units that the user buys and the app subtracts for each generation; credits come with a weekly subscription or in packs.

Keremcan Şeker, who trades as a sole proprietor in Turkey, released the app in Apple's App Store on 23 June 2026 and on Google Play on 15 September 2026. The revenue on this page is not his statement. He connected the app's RevenueCat account to TrustMRR, a public database of startup revenue. RevenueCat is a service that app developers place between their app and the app stores: it handles in-app purchases and subscriptions, and it records every purchase, renewal and refund. TrustMRR read that record through an API key: US$141,030 from 23 June to 13 October 2026, which is 16 weeks. RevenueCat's Revenue measure is gross revenue: what customers paid, minus refunds, before the app store keeps its commission and before sales tax. By calendar month the revenue was US$4,727 in the last 8 days of June, US$27,329 in July, US$43,734 in August and US$43,577 in September. It rose fast for two months and has been level since August, with a higher daily average in the first 12 days of October. The app is under four months old, so this page gives totals for stated periods and no yearly rate.

The profile also shows MRR, monthly recurring revenue, of US$51,764. That is more than the US$44,405 that customers paid in the last 30 days, and the reason is the method. Three of Boothie's four subscription plans are sold by the week, and RevenueCat counts each active weekly subscription as four payments. MRR is therefore the amount that the 2,216 active subscriptions would pay in one month if none of them cancelled, and weekly subscribers cancel often. The founder writes that every user came from TikTok carousels, posts made of several pictures that the viewer swipes through, published by "almost a dozen persona accounts", a term that usually means accounts that post as invented characters, and that he spent nothing on advertising. That text is from his sale listing: the business has been offered for sale since September 2026, now for US$1.5 million. This page could not find those accounts or any dated post by him about marketing. It then shows five earlier photo and video apps that grew fast and closed.

Boothie: US$141K verified revenue in 16 weeks, October 2026. AI photo restyling app, Turkey, solo founder, evidence grade A.

US$141,030 in verified gross revenue in the 16 weeks after launch, level at US$43,734 and US$43,577 in August and September 2026, read from the developer's RevenueCat account
FactValueGradeHow we knowSources
Verified revenue, all time to 13 October 2026US$141,030ATrustMRR, read from the RevenueCat API, last synced on 13 October 2026 at 18:28 UTC. The first revenue is in June 2026. The cached profile of 12 October showed US$139,181. Gross sales, as the next row explains. This is the headline figure.[1]
What the revenue figure measurescustomer payments minus refunds, before store commission and taxesCRevenueCat's documentation defines Revenue this way, and defines a separate measure, Proceeds, as revenue minus its estimate of taxes and store commission. TrustMRR's FAQ does not say which RevenueCat measure it imports; for its direct App Store connection it says that revenue is customer sales before Apple's commission. The FAQ also says that its figures can differ from a provider's own by up to 30%.[5, 4]
Verified revenue by calendar month, 2026June from the 23rd US$4,727, July US$27,329, August US$43,734, September US$43,577, October to the 13th US$21,663AThe monthly table of the profile. The five values add up to the all-time total. August and September together are 61.9% of it.[1]
Revenue per day, by monthJune US$591, July US$882, August US$1,411, September US$1,453, 1 to 12 October US$1,741calcCalculated: each monthly total divided by its days (8, 31, 31 and 30), and the profile's daily values for 1 to 12 October, US$20,896, divided by 12. August is 60.0% above July. September is 0.4% below August.[1]
Trendfast rise to August, level in August and September, higher in early October; no spikecalcCalculated from the profile's daily table, 29 full days from 14 September to 12 October: the first 14 days average US$1,376 and the last 14 days US$1,665, which is 21.0% more. Inside September, days 1 to 13 average US$1,603 and days 14 to 30 average US$1,338. The lowest day is US$1,053 (28 September) and the highest is US$2,734 (Saturday 10 October). The six days above US$1,700 are one Friday, two Saturdays and three Sundays.[1]
Verified revenue, 30 days to 13 October 2026US$44,405 in one monthAOne month of sales, not a yearly rate. The profile marks it 3.5% below the 30 days before, which puts those earlier 30 days at about US$46,000 (44,405 / 0.965).[1]
MRR, 13 October 2026US$51,764AUp 22.2% in 30 days according to the profile. RevenueCat converts each active paid subscription to one month: a weekly price is multiplied by 4 and a monthly price by 1. Credit packs and other one-time purchases are not counted.[1, 6]
Active subscriptions, 13 October 20262,216ARevenueCat counts paid subscriptions that still give access. A subscriber who has cancelled stays in the count until the paid week or month ends.[1, 7]
Average MRR per active subscriptionUS$23.36 a month, which is US$5.84 a weekcalcCalculated: 51,764 / 2,216, and that result divided by 4. In MRR, a weekly plan at the US price counts as US$27.96 (Plus), US$31.96 (Pro Weekly) or US$39.96 (Gold), and the monthly plan counts as US$19.99. The average is 83.5% of the lowest weekly value, so many subscriptions pay less than the US weekly price. Possible reasons are lower prices in other countries, a discounted first week, and the monthly plan. The profile does not give the split.[1, 6, 8, 12]
MRR against the last 30 days of revenueMRR is US$7,359 higher, or 16.6%calcCalculated: 51,764 minus 44,405. MRR is a count at one moment that assumes every active weekly subscription pays four times. Revenue is what was paid, and it includes credit packs, which MRR leaves out. For an app sold by the week, MRR is an estimate that assumes no cancellations, not a record of money paid.[1, 6]

In the 20 days to 13 October, MRR rose 36.2% and active subscriptions 58.3%, while revenue for 30 days moved only from $43k to US$44,405. The cause of that difference is not published.[2, 3, 1]
Paying users, founder's count9,800 in about three monthsCSeller's message on the profile page: "Three months in: $50K MRR, 9,800 paying users." The message is not dated and the count is not among the verified metrics.[1]
Share of those paying users who still subscribeabout 22.6%calcCalculated: 2,216 active subscriptions / 9,800 paying users. About 77% of the people who ever paid no longer subscribe. Approximate: the two numbers have different dates, and one user can hold more than one subscription.[1]
Revenue per paying userabout US$14.39calcCalculated: 141,030 / 9,800. That is close to two weekly payments of US$6.99.[1, 8]
Asking priceUS$1.5 million, down from US$2 million on 23 September 2026CSet by the seller. The profile gives 9 October 2026 as the first listing date, while TrustMRR's post of 23 September already announces the listing at US$2 million. The profile shows a multiple of 2.8 and 17 offers received. Calculated: 1,500,000 / (44,405 times 12) = 2.81, so the marketplace's multiple compares the price with twelve times the last 30 days of revenue.[1, 3]
Profit margin, last 30 days55.0%CShown on the profile. It is not in the profile's list of metrics that come from payment records, and the costs behind it are not published.[1]
Store commission15% at Apple for developers in its Small Business Program; on Google Play subscriptions 10% plus a 5% billing fee, or 15%, depending on the marketCApple's and Google's own pages. Developers new to the App Store can qualify for Apple's program; whether this developer is enrolled is not verified. Calculated: if 15% applied to all sales, the developer's share of US$141,030 would be US$119,876 before taxes and costs.[16, 17]
AI modelGoogle's Gemini, called from a Firebase backendCThe company's privacy policy and terms of 23 July 2026. They do not name the Gemini version. The policy says that photos are sent to the backend only to call the model and are not stored there.[11, 12]
Google's list price for one generated image, October 2026US$0.0336 to US$0.134CGoogle's pricing page, for an image of 1,024 by 1,024 pixels: US$0.0336 with Gemini 3.1 Flash Lite Image, US$0.067 with Gemini 3.1 Flash Image and US$0.134 with Gemini 3 Pro Image. The same page marks Gemini 2.5 Flash Image, at US$0.039 an image, as deprecated with a shutdown date of 2 October 2026.[14]
Model cost of one Plus week with every credit usedUS$1.18 to US$2.35, against a price of US$6.99calcCalculated: 5 credits a day times 7 days = 35 credits; 35 times US$0.0336 = US$1.18 and 35 times US$0.067 = US$2.35. After a 15% commission the developer keeps US$5.94 of the US$6.99. This assumes that one credit is one image of that size. The company publishes neither the model version nor the number of credits per image.[12, 14, 8]

How users were foundTikTok carousels from "almost a dozen persona accounts" in the US, Germany and Turkey; no paid adsCSeller's message on the profile, written for buyers; the accounts are offered as part of the sale. Not verified: this page did not find the accounts, and the founder's X account has no post about marketing. Two details agree with it: the website has a notice for visitors who arrive in TikTok's in-app browser, and the App Store listing is translated into German.[1, 10, 8, 13]
Founder's audience on X33 followers, 6 postsCRead through the fxtwitter API on 13 October 2026. The posts returned are three reposts of TrustMRR and one post in Turkish that is not about the business. The users did not come from a personal audience.[13]
Team1 founder named; team size not publishedCTrustMRR lists one founder. The seller in the App Store and the developer on Google Play carry his own name, and the terms call the business a sole proprietorship established in Türkiye. The app's bundle identifier contains a second given name next to his. No source presents a second person as part of the business, so this page names none.[1, 8, 9, 12]
Outside fundingnone reportedCSeller's message: "Launched in June no money, no paid ads." No investor is named in any source read for this page.[1]
Earlier apps by the foundernone foundBHis App Store developer account and his Google Play developer page each list only Boothie, and his TrustMRR founder page lists one startup.[8, 9, 1]
Time from launch to the headline figure112 days, which is 16 weeks or about 3.7 monthscalcCalculated: 23 June to 13 October 2026. The card on this site shows 4 months, rounded.[1, 8]

How to read this table: a grade A value was read by TrustMRR from the developer's RevenueCat account through an API key; it is not a founder statement. A grade B value is published by Apple or Google in a store record. A grade C value is a founder statement, a profile field that the founder filled in, the company's own policy pages, or a vendor's document. A "calc" value was computed on this page from the rows named in its note.

Editor with film filters00runs on the phone, no AI

The app is free to download, and the editor with film filters is free. Apple's listing gives seven in-app purchases with a name and a price but no period. The terms of service, dated 23 July 2026, say that Plus and Gold are weekly, with 5 and 10 credits a day that do not carry over to the next day. The terms give higher prices than the listing: US$7.99 a week for Plus and US$12.99 a week for Gold, with a possible discount on the first week, no free trial and no yearly plan. The terms do not mention the two Pro plans. Credit packs are sold only to subscribers. Prices differ by country: the German store lists Plus at 8.99 euros and the Turkish store at 249 Turkish lira. Google Play lists in-app purchases from US$2.99 to US$11.99 per item. The third column holds the listed price with its period.

03

Why it worked

Four causes, in the order they mattered. Each one is a reusable lesson.

01

A look that people already wanted

Boothie did not have to create demand. The BBC reported in February 2023 that TikTok videos with the hashtag #digitalcamera had more than 220 million views in twelve months and that young people were buying cameras from the early 2000s. Boothie sells the result of such a camera without the camera, and names its looks after it: Y2K digicam, Powershot flash, night flash.

02

Many small TikTok accounts, no advertising

According to the founder, all users came from carousels posted by almost a dozen persona accounts in the United States, Germany and Turkey, and he paid for no ads. A carousel of before and after pictures shows the whole product in one post. This is his statement to buyers and this page could not check it. The store ratings fit a start in Turkey: 194 of 245 ratings in four stores are from Turkey.

03

A weekly price with a daily credit limit

A weekly price of US$6.99 is a small decision for someone who wants the look for one evening's photos. The daily limit of 5 or 10 credits, which do not carry over, puts an upper limit on what one subscriber can cost in model fees. Subscribers who want more buy credit packs.

04

A rented model and a free editor

The founder trained no model. The app sends the photo to Google's Gemini and pays by the picture, so the cost follows the usage and there was nothing to build before the first sale. The free editor with film filters runs on the phone and costs nothing to serve, so the app can be useful to people who never pay.

How it was built

These details come from the company's privacy policy and terms, from the TrustMRR profile fields that the founder filled in, and from the store listings. They are grade C, except the store records, which are grade B. [1, 11, 12, 8, 9, 10]

  • Technology listed on the profile: Swift and React Native for the app, RevenueCat for purchases.
  • The AI pictures come from Google's Gemini. The app sends the selected photo to a Firebase backend, which calls the model and returns the result. The policy says that photos and results are not stored on the server and that the history stays on the phone.
  • The free mode, called Classic Photobooth in the policy, applies film filters on the phone and sends nothing.
  • No account is needed. RevenueCat ties purchases to an anonymous identifier of the installation, and Firebase App Check confirms that requests come from an unmodified copy of the app.
  • Analytics with PostHog record events such as paywall viewed, purchase started and daily credits used up. Crash reports go to Firebase Crashlytics. The policy says that screen recording and click capture are turned off.
  • Seven versions in 16 weeks: 1.0 and 1.1 on 23 June, 1.2 on 2 July, 1.3 on 15 July, 1.4 on 23 July, 1.5 on 1 September and 1.6 on 12 October 2026. The Android version followed on 15 September.
  • The legal pages are two Notion pages, and the website is a single page with store buttons.

The dead that came before

Five companies in the Loot Drop database sold photo or video effects, or grew on another company's platform, and closed. The values below are from that database and are not independently verified.

Died 2011 to 2014Burned US$30M

Viddy

The promise

Filters that make a phone video look professional, shared with friends.

Why it died

People tried it once and did not come back. Instagram added video in 2013, and Vine spread at the same time.

Died 2010 to 2017Burned US$86M

Mobli

The promise

A photo and video sharing app with filters, promoted by celebrities.

Why it died

Instagram had started earlier and Facebook bought it. Mobli had no feature that made users switch.

Died 2005 to 2012Burned US$3.5M

Picnik

The promise

Photo editing and effects in the browser, with nothing to install.

Why it died

Google bought it in 2010, moved the technology into Google+ and closed the service in 2012. Phone apps with built-in filters took the users.

Died 2013 to 2019Burned US$19.2M

Everalbum

The promise

Unlimited photo storage with automatic sorting, sold by subscription.

Why it died

It charged for features that Google Photos gave away free, and users chose the free one.

Died 2015 to 2016Burned US$14M

Meerkat

The promise

Live video from a phone to your Twitter followers.

Why it died

All its growth came through Twitter. Twitter bought a competitor, Periscope, and cut Meerkat's access.

What changed

The five earlier companies raised between US$3.5 million and US$86 million to build an effect together with the place where people share the result, or to grow on a platform that they did not control. Each lost when a larger company added the same effect or closed the access. Boothie is exposed to the same two risks: any app can add a digicam look, and all of its users come through TikTok.

What differs is the cost of trying. Boothie builds no network and trains no model. It rents the image model from Google by the picture, sells through the app stores, and charged from the first week, so one person reached US$141,030 of verified sales in 16 weeks without investors. Viddy and Mobli needed tens of millions of dollars before they knew whether users would stay. Boothie will learn the same answer from its own weekly renewals, with little money at risk.

05

Can one person copy it now?

The method, yes. This look, for a limited time.

A rented image model, a weekly price with a daily credit limit and picture posts on TikTok are open to anyone, and the founder says he started with no money. The digicam look is one trend among many and others sell it too, so a copy needs its own look and its own audience. What nobody can know yet is how long a weekly subscriber stays: the data covers 16 weeks.

Where it is still open: Other looks, and other countries and languages. The founder names two things he has not done: more content for the United States, and work on retention.

  1. 1Choose a visual look that people already post and save, and check that it is spreading on TikTok in your language.
  2. 2Build the effect on a rented image model, and add free filters that run on the phone so the app is useful before payment.
  3. 3Sell by the week with a fixed number of credits a day, so that the model cost of one subscriber has an upper limit.
  4. 4Post before and after carousels from several accounts in each country, and measure which country pays.
  5. 5Connect the payment records to a public verification service early, so that the figures can be checked if you decide to sell.

What to watch

The risks are the mirror image of the causes above.

Weekly subscriptions end fast

RevenueCat's State of Subscription Apps 2025 report says that weekly plans lose 30% to 50% of subscribers at the first renewal and that weekly plan retention rarely exceeds 10% at six months. Boothie's own numbers agree with this: by the founder's count of 9,800 paying users, about 77% no longer subscribe, and the average paying user has paid about US$14. The churn rate itself is visible on TrustMRR only after login and was not read.

Sixteen weeks of data, and a seller's text

The verified record starts on 23 June 2026. It shows two months of growth and two level months, which is too short to tell a business from a trend. The description of the marketing comes from a sale listing. Its asking price was US$2 million on 23 September and US$1.5 million by 12 October 2026. TrustMRR also says that its figures can differ from the provider's own by up to 30%.

The model is rented, and the result is the complaint

Every AI picture is a paid call to Google's Gemini, at a list price of US$0.0336 to US$0.134 an image depending on the model. Google sets that price and retires models: its pricing page gives 2 October 2026 as the shutdown date of Gemini 2.5 Flash Image. Any competitor can rent the same model at the same price. The most frequent complaint in the written reviews is that the picture no longer looks like the user, which the website promises will not happen.

The look is a trend

The digicam look has been spreading on TikTok since at least 2022, and a visual trend can pass. Later versions of the app added film looks and a beauty editor. No source shows which looks the revenue depends on.

One platform brings all the users

The founder says that every user came from TikTok carousels posted by persona accounts. A change in how TikTok shows such posts, or the loss of those accounts, would stop new users. The accounts are not named in any source, so their reach could not be checked.

The stores take a share and set the rules

If the developer is in Apple's Small Business Program, Apple and Google each keep about 15% of a subscription payment, and the developer's share of the headline figure is near US$119,876 before costs. Apple's review guidelines say not to submit apps that are indistinguishable from what is already widely available (4.3), require a clear description of what a subscriber gets for the price (3.1.2), and require explicit permission before personal data is shared with a third-party AI (5.1.2). A photo of a face that is sent to Gemini falls under the last rule.

Many apps sell the same thing

The founder's own listing names four larger apps in the same category, Tezza, Prequel, Dazz Cam and WayShot, with yearly revenue figures that this page did not verify. Google Play shows a row of similar AI photo apps next to Boothie. Photo AI and HeadshotPro, the two other photo products on this site, train a model on the customer's own photos and sell on the web, and their figures are founder statements dated 37 and 43 months after launch. Boothie's figure is verified but covers 16 weeks, and it comes from small weekly payments inside app stores, which arrive faster and stop sooner.
