Bible Note Taker, MenuFit, Vinyl Snap, Lang Lang Learn… apps nobody's heard of, quietly pulling $40K-$300K/mo
Greg's framework: a good niche has four ingredients — identity + urgency + stakes (money/reputation) + recurrence. "If all four are there, an AI app can eat it."
Fewer bars = easier, cheaper, or faster for an AI-assisted solo builder. Editorial judgments based on the case details.
[Video] "Apps launched in the past 180 days making $50K/mo": Flash Loop (AI curiosity-bait video generation, $50K/mo), Bible Note Taker (sermon recordings + AI summaries + lock-screen daily verses, $60K/mo), AI Home Decor (photo → interior-makeover renders, $100K/mo), MojiLab (AI stickers, $100K/mo), Vinyl Snap (scan vinyl records for valuations, $70K/mo), Genora AI (a multi-LLM aggregator wrapper — still running older models, $300K/mo), Logo Maker (prompt-generated logos, $6.99/week, $200K/mo), MenuFit (scans restaurant menus and recommends dishes by fitness goal, $60K/mo on just 30K downloads = extremely high per-user value), Lang Lang Learn (AI English speaking partner, $300K/mo), ZozoFit (3D body scanning, $40K/mo).
None of these apps started with an audience. They started with a search box. Logo Maker does $200,000 a month on 100,000 downloads mostly because anyone who opens the App Store and types logo maker lands on it, which is why Isenberg calls the name the ASO and singles out ZozoFit, the lowest earner at $40,000, as the worst name on the list. Every app here cleared its first month somewhere between 30,000 and 300,000 downloads with no press and no founder brand. Two engines do that work. One is exact-match keyword interception, which is why the copyable move is the niche inside the niche: not another Lang Lang Learn but business English interview practice, owning that one phrase outright while the broad term stays contested. The other is output that travels on its own, the way Flash Loop's AI clips spread through TikTok and Reels. Pick the engine before building, because a scan-and-value app like Vinyl Snap has nothing shareable and lives or dies on the keyword alone.
Revenue here arrives within minutes of install, not months. These are hard-paywalled subscriptions placed immediately after the one transformation the app performs, and the pricing is aggressive: Logo Maker charges $6.99 a week or $40 a year, and Bible Note Taker sells weekly and yearly plans side by side. The ratio to watch is revenue per download in the first thirty days. Most of the list sits near one dollar, while Logo Maker and MenuFit both sit near two, MenuFit turning 30,000 downloads into $60,000 because someone deciding what to order against a fitness goal will pay more than someone making a sticker. That gap is set by stakes, not by features. A scan that tells a collector whether the record in their hand is a $10 album or a $1,000 one carries weekly pricing comfortably. The practical rule is to charge weekly from day one and let the yearly plan catch the people who intend to keep the habit, rather than launching free and retrofitting a paywall later.

Data credibility: Third-party list data, relayed by Greg Isenberg. All revenue figures are founder-reported or estimated by the video creator; none are audited.
Two loops run at once. The store loop is mechanical: rank for the phrase, collect downloads, and the downloads defend the rank, which is the entire moat for a Logo Maker or a Vinyl Snap. The usage loop is the one that decides whether the revenue survives month three, and it comes from the niche rather than the product. Bible Note Taker rides a fixed weekly attendance shared by over a billion Christians, MenuFit gets opened every time someone sits down in a restaurant, and Lang Lang Learn fits short daily sessions that build a habit. That is the repetition leg of the four-part test, alongside identity, urgency and stakes. The turn happens when opens come from the recurring need instead of the novelty, and the apps engineer for it directly: Bible Note Taker pushes a daily verse to the lock screen, a widget pattern that has been the growth lever of the past six to nine months, and MojiLab keeps shipping fresh sticker packs so freshness holds retention.
The flat stretch in this category looks like a finished app sitting in the store while nothing happens, and it usually means one of two diagnoses rather than bad luck. Either the chosen phrase is already owned, in which case the fix is to move further down the niche instead of polishing the build, or the audience has no recurrence, in which case installs arrive and never return and no amount of interface work rescues it. Judge on paywall conversion at first open and on day-seven return rate, both readable within a fortnight of launch, long before monthly revenue means anything. Every app on this list launched inside a 180-day window, which cuts both ways: the openings are real and the imitators arrive fast, so beyond a first-mover position and a keyword there is nothing to defend. That argues for a cadence rather than a bet, one niche experiment a month, each scored against the five-part test of spends money, repeating problem, photo input, accuracy matters, bad existing tools.
[Video] 1) The five-part test: find a group of people who spend money, have a recurring problem, use photos/video as input, care about accuracy, and are stuck with terrible existing tools. 2) "Start with a nerve": a good niche has four ingredients — identity + urgency + stakes (money/reputation/time) + recurrence; "if all four are there, an AI app can eat it." 3) Build around a single high-intent input (photos are king): the harder the input is to interpret, the more instant value AI creates — photo → diagnosis, object → valuation, room → design plan. 4) One job done brutally well: one task × one obsessed audience × one recurring need. 5) An interface that's "stupidly simple" — one screen, one button, one transformation. 6) The name is the ASO.
[Video] Bible Note Taker: 1B+ Christians worldwide with fixed weekly attendance = a built-in usage cadence; lock-screen widgets are the growth trend of the past 6-9 months — portable to mosque sermons, AA meetings, Torah study. Vinyl Snap: collectibles = nostalgia + real money; "Pokémon cards beat the S&P 500 over 15 years" — used books, comics, sports cards, vintage clothing can all do "scan-identify-value." Genora AI is the most sobering: "It's not the best product, but it works — most users don't want five AI apps, they want one place." Bonus ideas: an AI golf-swing coach, used-car analysis (VIN + photos → repair-risk report / haggling script), pet health scanning, business-English speaking practice (own a single ASO keyword outright).
[AI] Be clear about the evidence level: all of this is list data relayed by a creator, with zero founder confirmation — use it as "direction validated," not "numbers exact." How to use it: as an idea ammo depot + Greg's four-ingredient yardstick. Each month, pick one and build the "niche within the niche" (don't build Lang Lang Learn; build "business-English interview practice" and own that ASO keyword). The shared weakness: beyond first-mover advantage and ASO positioning there is no moat — enter with a distribution plan in hand (see the Kletchi and Loic cards).
That was one of the 50 breakdowns open to everyone. The Unicorn Club opens the other 1,285 at the same depth — plus pain-point filters and 10 build specs a week.
