Brawler
Brawler, sold on the App Store as BRAWLER- Future of Boxing, is an iPhone app that coaches boxing. The user uploads a video of shadowboxing, bag work or sparring, and the app's AI scores the technique in seven areas, from stance and guard to head movement and range control, with corrections and drills. It also has an AI chat coach, training programs, a round timer and AI food logging. Every feature sits behind a paywall, a screen that asks for payment before the app can be used: US$9.99 a month or US$59.99 a year. One sale listing marks it as made with Rork, a no-code AI app builder that writes a phone app from instructions in plain language, and names OpenAI as its AI provider.
The app went live on 1 May 2026, sold by Brawler LLC. The Superwall Podcast of 15 October 2026 counts it among the three apps of George Lampropoulos, and his first app has its own story on this site: Wrestle AI. Brawler's App Store page links to wrestleai.app as its developer website. TrustMRR reads the app's sales through an API key, a password that lets one program read another program's data, for RevenueCat, a service that records in-app subscription purchases for app makers. It shows US$146,852 in total revenue to 16 October 2026 and MRR, monthly recurring revenue, in which a yearly plan counts as one twelfth of its price, of US$22,600 from 4,180 active subscriptions. September, at US$48,741, was more than double August.
The revenue figures are grade A, because they come from the app's own subscription records, not from screenshots. The ownership is less clear. TrustMRR names no founder. One whatsthe.app listing names the founder as @Georgelampro20 and asks US$200,000; a second whatsthe.app listing for the same app, named Strikr, names no one, gives a team of 2 and asks US$127,940. Daily revenue in mid-October was about 45% below late September. The page also shows earlier coaching and fitness companies that failed, and the risks of a five-month-old app that is offered for sale.
The numbers, graded
Each row shows the evidence grade and the source numbers from the list at the end of this page. The grades are explained in How Aiolum verifies.
| Fact | Value | Grade | How we know | Sources |
|---|---|---|---|---|
| Monthly recurring revenue (MRR), 16 October 2026 | US$22,600 | A | TrustMRR, revenue synced on 16 October 2026 at 22:57 UTC through a RevenueCat API key. 4,180 active subscriptions. TrustMRR gives MRR growth of 76.7% in the last 30 days. | [1] |
| Run rate from the October 2026 MRR | about US$271,200 a year | calc | Calculated: US$22,600 times 12. | [1] |
| Total revenue, May to 16 October 2026 | US$146,852 | A | TrustMRR, all time. The six monthly values in the profile add up to US$146,851; the difference of US$1 is rounding. | [1] |
| Revenue in the last 30 days, to 16 October 2026 | US$58,752 | A | TrustMRR, which gives growth of 149.3% over the 30 days before. Revenue is the money received, so a yearly plan counts in full on the day it is paid; that is why this is 2.6 times the MRR. | [1] |
| Revenue by month, 2026 | May US$4,152; June US$17,996; July US$26,161; August US$23,482; September US$48,741; October to the 16th US$26,319 | A | TrustMRR monthly timeline. May is the month of release. | [1] |
| Rise in September 2026 | US$25,259 more than August, plus 107.6% | calc | Calculated: US$48,741 minus US$23,482. September was also 86.3% above July. No source explains the rise. The App Store shows version 2.3, with a boxing course, on 17 August and version 2.5.0 on 5 September. | [1, 2] |
| Daily revenue, late September and mid-October 2026 | about US$2,495 a day on 18 to 30 September, about US$1,368 a day on 10 to 16 October | calc | Calculated from TrustMRR's daily table: 45.2% lower. The October average to the 16th, US$1,645 a day, is still close to the September average of US$1,625 a day. | [1] |
| whatsthe.app listing named Brawler, 1 October 2026 | US$48,709 in 28 days, MRR of US$18,768, 3,407 active subscriptions, 22,026 new customers in 28 days | A | Read by whatsthe.app through RevenueCat, last updated on 1 October 2026. The founder is named as @Georgelampro20, and the leaderboard data marks the listing "revenuecat-verified". | [3, 5] |
| whatsthe.app listing named Strikr, 2 October 2026 | US$49,923 in 28 days, MRR of US$19,093, 3,464 active subscriptions | A | It links the same App Store page and gives the same bundle ID, app.rork.boxing-pro-ai-trainer. No founder is named, the leaderboard data marks it "revenuecat", and the page says that the RevenueCat API key expired, with data last updated on 2 October 2026. | [4, 5] |
| Asking prices | US$200,000 on TrustMRR and on the whatsthe.app Brawler listing; US$127,940 on the whatsthe.app Strikr listing | C | Set by the sellers. TrustMRR: first listed on 18 June 2026, 17 offers received. whatsthe.app: the Brawler listing was created on 19 June 2026 and the Strikr listing on 12 July 2026. | [1, 3, 4, 5] |
| Asking price compared with revenue | about 0.74 times a year of MRR, or 0.28 times the last 30 days of revenue times 12 | calc | Calculated: US$200,000 divided by US$271,200, and by US$705,024. TrustMRR shows the second ratio rounded to 0.3x. | [1] |
| Founder | George Lampropoulos | C | The Superwall Podcast description of 15 October 2026 counts Brawler among his three apps. The whatsthe.app listing names the founder as @Georgelampro20. TrustMRR names no founder. | [6, 3, 1] |
| Team | 2 people | C | Self-reported on the Strikr listing, which names no one. The podcast description mentions a popup that lets users book a call with "the founders", without saying which app. No second person is named for Brawler in any source. | [4, 6] |
| Outside funding | none reported; listed as bootstrapped | C | Strikr listing. No source mentions investors. | [4] |
| Seller on the App Store | Brawler LLC | B | Apple's record. The developer page of Brawler LLC lists only this app. The app's developer website link points to wrestleai.app, and its privacy policy link is the same Termly document that the Wrestle AI page links. | [2, 7, 8] |
| His three apps together, October 2026 | almost US$41,000 MRR and US$84,000 in 28 days | C | Podcast description: Wrestle AI, Brawler and a fitness app, with no split per app. On this page's calculation, Brawler's MRR was about 46% of the three-app MRR on 1 October (US$18,768) and about 55% on 16 October (US$22,600). | [6, 3, 1] |
| Self-reported costs | marketing spend of US$10,000 a month; profit margin of 55% | C | Strikr listing, marked by whatsthe.app as unverified and self-reported. TrustMRR shows a profit margin of 50.0% for the last 30 days. | [4, 1] |
| Users | "over 10k boxers" in the seller's text; 1,200 in the founder's TrustMRR estimate | C | Neither is verified, and they do not agree. The verified count is 4,180 active subscriptions on 16 October 2026; whatsthe.app counted 23,617 active customers on 1 October. | [3, 1] |
| App Store ratings, 16 October 2026 | about 2,000 ratings, average 4.8 of 5 | B | Apple's page shows 2K ratings, and its page data gives 2,012. whatsthe.app shows about 1,600 of them from the United States. | [2, 3] |
| Release | 1 May 2026 | C | The worldwide release date on both whatsthe.app listings and the founded date on TrustMRR. The oldest version in the App Store history is 1.0.2 of 6 May 2026. | [3, 1, 2] |
| Time from release to the October 2026 figure | 5 months | calc | Calculated: May 2026 to October 2026. | [1] |
How to read this table: a grade A value was read by TrustMRR or whatsthe.app from the app's RevenueCat account through an API key. A grade B value is a record that Apple shows on the App Store. A grade C value was written by the seller or the founder, on a listing, on the App Store or in a podcast description. A "calc" value was computed on this page from the rows above it.
| Plan | Per month, billed yearly (US$) | Per month, billed monthly (US$) | Limit |
|---|---|---|---|
| Monthly | 9.99 | all features | |
| Yearly | 5.00 | US$59.99 a year | |
| Discounted Yearly BRAWLR Premium | 2.50 | US$29.99 a year; named as a discount | |
| BRAWLER Pro Monthly | 5.99 to 12.99 | three prices listed: US$5.99, US$7.99, US$12.99 | |
| BRAWLER Pro Yearly | 1.50 to 3.33 | four prices listed: US$17.99, US$24.99, US$35.99, US$39.99 a year |
Every feature needs a subscription. The App Store lists ten in-app purchases. The first three rows are the prices that TrustMRR and both whatsthe.app listings show for the app; Apple also lists seven BRAWLER Pro prices, and no source says which users see them. Yearly plans are paid once a year; the per-month values in the table are the yearly price divided by 12.

Why it worked
Four causes, in the order they mattered. Each one is a reusable lesson.
A second sport, the same structure
The App Store pages of Wrestle AI and Brawler show the same design: an AI breakdown of a training video as the main feature, a calorie tracker and a weight-cut mode, and every feature behind a subscription of US$9.99 a month or US$59.99 a year. Boxing can be trained alone, and the app is built for that: shadowboxing, bag work, pad work sessions, a punch callout mode with audio cues and a round timer.
Paid reach: ads and creators
The founder's TrustMRR profile and the Strikr listing name Meta Ads and influencers as the marketing channels, and the Strikr listing gives a self-reported marketing spend of US$10,000 a month. whatsthe.app counted 22,026 new customers in the 28 days to 1 October 2026. The podcast on his apps covers raw screen recordings run as ads, and creator videos in stitch and ranking formats that also work as paid ads; a stitch is a TikTok video that begins with a clip from another video. It does not split these results by app.
Paywall before use
The app is free to download, but every feature needs a subscription. Version 1.0.2, five days after release, changed the onboarding and added an "abandon paywall". The App Store lists ten in-app purchases, from US$5.99 a month to US$59.99 a year, while the listings show three of them.
Money from yearly plans
MRR counts a yearly plan at one twelfth of its price, while revenue counts the whole payment on the day it is made. Brawler's revenue in the last 30 days, US$58,752, was 2.6 times its MRR of US$22,600, so much of the money arrives as yearly plans paid in advance. whatsthe.app shows the same ratio for its 28 days, 2.6, as a "cash flow index".
Built with a no-code builder and OpenAI
The app's bundle ID, its unique name in Apple's systems, is app.rork.boxing-pro-ai-trainer, and whatsthe.app shows a "Made with Rork" badge on the Strikr listing. That listing names Swift, SwiftUI, Supabase and OpenAI as the technology; the founder's TrustMRR profile names Swift, SwiftUI, Supabase and RevenueCat.
How it was built
These details come from the sale listings, the founder-entered fields of the TrustMRR profile and the App Store page. They are grade C unless the App Store is the source, which makes them grade B. [1, 2, 3, 4, 5, 8]
- Made with Rork, a no-code AI app builder: the bundle ID starts with app.rork, and whatsthe.app shows a "Made with Rork" badge. The Brawler listing also links a Google Play address that starts with app.rork.
- Swift and SwiftUI for the iPhone app, Supabase for the backend and RevenueCat for subscriptions, according to the founder's TrustMRR profile. The Strikr listing adds OpenAI for the AI.
- The release note of 1 August 2026 says that video analysis, coach chats and nutrition moved to "our most powerful AI models yet". No source names the models.
- Food logging works from a photo, a barcode or voice. The video analysis covers seven areas of technique and returns corrections and recommended drills.
- 25 versions in the App Store history from 6 May to 4 October 2026. Most release notes say only "bug fixes".
- The privacy policy, terms of service and license agreement are hosted on Termly. The privacy policy link is the same document that the Wrestle AI page links.
Tools named in the sources
Each one opens its page in the Tools tab, with every story that uses it.
The dead that came before
Four companies in the Loot Drop database promised coaching or fitness help through a service, an app or a device. The values below are from that database and are not independently verified.
Arivale
The promiseHealth coaching built on genetic, blood and activity data, for US$3,500 up front and US$99 a month.
Why it diedThe coaching was done by people, and each coach could handle only 50 to 100 clients. The record puts the cost at more than US$4,700 a customer a year against US$1,188 a year of revenue after the first year.
Charge Running
The promiseLive online running classes with real-time audio coaching, like a personal trainer at home.
Why it diedUsers preferred flexible times to scheduled classes, and AI fitness apps such as Future offered personal coaching on demand.
Jawbone
The promiseUP fitness trackers that turned daily activity data into health advice.
Why it diedFitbit and Apple had more money and moved faster. Product recalls, poor customer service and long legal battles used up its resources.
Fitmob
The promiseFitness classes at many studios and pop-up venues without a gym membership.
Why it diedRunning physical classes with many venues added cost without matching revenue. ClassPass, with a larger network, took the market, and users moved to on-demand digital fitness.
What changed
Arivale and Charge Running sold coaching that needed people: coaches with 50 to 100 clients each, or instructors at fixed times. Jawbone needed hardware and Fitmob needed venues. All four spent investors' money, from US$5 million to US$930 million, and lost to larger or more flexible competitors.
Brawler's coach is software: it answers at any hour, reviews a video without a human coach and needs no venue or device beyond a phone, and the listings report a profit margin of 50% to 55%. What did not change is the competition. Charge Running's record says that AI fitness apps took its market, and the same can happen to a small AI app when Apple or a large fitness company adds AI features: Apple put Workout Buddy, which needs Apple Intelligence, on the Apple Watch in September 2025.
Can one person copy it now?
The method, yes. The head start, no.
Brawler is a second app built on a structure that had already worked once: an AI breakdown of training video for one combat sport, a paywall before use, ads and creators. The tools are open to anyone: a no-code AI builder, a general AI model, RevenueCat for subscriptions. A newcomer does not have the lessons of a first app that already sold, and both listings offer this one for less than a year of its MRR.
Where it is still open: Sports and exercises that people train alone and can film with a phone, as long as no app and no large fitness company serves them yet.
- 1Start from an app format that already sells in one niche and move it to a neighbouring niche where people train alone and can film themselves.
- 2Build it with a no-code AI builder, use a general AI model for the analysis and RevenueCat for the subscriptions.
- 3Put every feature behind a subscription, with a monthly plan, a yearly plan and a discounted yearly offer.
- 4Connect the revenue account to a verification site such as TrustMRR, so that buyers can see real figures if you sell later.
What to watch
The risks are the mirror image of the causes above.
Two sale listings, two prices
TrustMRR and a whatsthe.app listing that names @Georgelampro20 ask US$200,000. A second whatsthe.app listing, created on 12 July 2026 under the name Strikr, links the same App Store page and bundle ID, names no founder, gives a team of 2 and asks US$127,940. Both listings read the revenue through RevenueCat API keys, which whatsthe.app describes as the seller's read-only keys, so both were made by someone with access to the app's revenue account. No source says whether the same people made both listings, or why the prices differ.
Five months of history
The app was released on 1 May 2026 and listed for sale on 18 June 2026, seven weeks later. Revenue more than doubled in September, but daily revenue on 10 to 16 October, about US$1,368 a day, was 45% below the level of late September. The founder's user estimate on TrustMRR (1,200) and the seller's text ("over 10k boxers") do not match the verified 4,180 active subscriptions.
Large fitness companies and other AI boxing apps
Apple added Workout Buddy, a feature that needs an iPhone with Apple Intelligence, to the Apple Watch with watchOS 26 on 15 September 2025, and watchOS 27 added Spanish to it on 14 September 2026. Direct competitors are other AI boxing coaches: Boxer AI from Impact Development LLC, first released on 8 March 2026, with about 2,000 ratings, and JAB AI from Limitnil, first released on 19 August 2025, with 489 ratings. The App Store shows both next to Brawler, and whatsthe.app lists Boxer AI for sale at US$7,748 of MRR.
A competitor's name in the description
The App Store description ends with a list of search words that starts with "Boxer Ai", the name of a competing app. Apple's App Review Guideline 2.3.7 tells developers not to pack metadata with "trademarked terms, popular app names" and says that Apple may modify inappropriate keywords at any time or take other appropriate steps to prevent abuse.
Dependence on Rork and OpenAI
The app was made with Rork, and the seller names OpenAI as the AI provider. A price change at OpenAI changes the cost of every video analysis and every chat. A review of July 2026 says that the AI analysis "says a lot of the same things no matter how well you do them". The Strikr listing says that the source code, written with Rork, is included in a sale.
A teen audience and body data
The app is rated 13+. Its privacy label lists photos or videos, audio, body data (hands and head) and environment scanning among the data it collects, though not linked to the user's identity, and purchase data as used to track users across other companies' apps and websites.
