24 ratings, #12 on Hungary's Education Top Grossing: a nail champion moved her paid members into her own app
What it is A subscription app for nail techs, launched by a Hungarian nail champion: training videos, livestream replays, an AI assistant that can answer "why is my gel lifting," real expert advisors, AI design images, and a client booking calendar, at roughly 13 or 23 euros a month.
Why it took off She already had monthly paying members on her website and Patreon. The app's VIP price matches the old price, so existing members moved over without paying more. Her and the brand's social accounts, launch giveaways, and new products that debut only in the app brought in a wave of peers. The Hungarian Education Top Grossing chart has a low bar, so a few hundred monthly subscribers can reach the top 15.
CHow you could follow Building a nail AI app as an unknown won't work. Instead, go find vertical-profession KOLs in small-language markets who already collect monthly fees on Patreon or Kajabi, and move their members into your app. Match the premium price to the old member price, add AI Q&A and pro tools trained on their content, and try to get a revenue share on renewals beyond the dev fee.

Hungarian nail tech Marton Bettina built an app called Nailvana, sold to nail techs, not to their clients. It has tutorial videos, replays of live sessions, an AI assistant that answers "why is my gel lifting," and a booking calendar, at 4 990 or 8 990 forints a month. It went live at the end of August, and by 6 Nov it had only 24 ratings on iOS, yet it ranked #12 in Hungary's Education Top Grossing chart, sitting right next to global apps like Duolingo. That ranking didn't come from the App Store. Her paid membership had been running for years and moved to a new place to take payment, and what carried it was her. Below: what it sells, where the ranking came from, how much money is involved, and what you can take from it.
A fish-tank nail with 710k views
In 2023 October, Marton Bettina posted on TikTok a "Aquarium köröm" (fish-tank nail), with sequins and beads sealed in the nail tip that drift like snow in a snow globe when the hand moves. The video got 710k views and 48k likes, the most popular on her account (TikTok @mbettinanails, read 11-06).
Three years later, that technique became the thing she sells. In early November, a page appeared at nailvana.app/learn with the header "48 days until Christmas": a 48-minute fish-tank nail masterclass taught in Hungarian, one-time payment with unlimited replays, card checkout, instant access. The November 4 1.0.109 update notes added that videos not included in the subscription can be bought individually in the app.
She has won two Nailympia gold medals (2012 London, 2023 Orlando), has done nails in a salon since 2009, and founded her own gel polish brand, NAILVANA, three years ago. Nail techs know her as a person. The app is a new place to take money for the influence she already had.
What it sells to nail techs
The first line of the store description reads "amikor a vendég már a székben ül": when the client is already in the chair, you can use it right away. It is a tool for working:
- Video library: tutorials from nail prep to decoration, short inspiration videos, and product demos, updated monthly.
- Troubleshooting (Hibajavító): describe what went wrong with a nail, such as gel bubbling, lifting tips, yellowing topcoat, or a client allergy. It lists possible causes and fixes and accepts photos. If the answer isn't good enough, you can tap to pass it to a real expert. The official site says the AI was "trained by" the NAILVANA professional team.
- Design images: write what the client wants, the AI generates a design, and you can also try colors on your own photos.
- Livestreams: team instructors stream live, you can ask questions while watching, and replays are available later.
- Calendar and salon profile: manage clients and bookings, and keep a record of each client's nail "history."
Pricing has three tiers (App Store description, Hungary store):
| Tier | Pricing | Includes |
|---|---|---|
| Free | 0 | Troubleshooting total 3 times, design images 3, free-marked videos |
| Pro | 4 990 Ft/month (about 13 euros) | 30 Q&A per month, 50 design images, 3 live expert consultations per month, all Pro videos, all livestream replays |
| VIP | 8 990 Ft/month (about 23 euros) | All of Pro, plus 50 Q&A per month, unlimited expert consultations, 2 full masterclasses per month, and exclusive VIP livestreams |
Individual videos and masterclasses can also be bought separately. The app was developed by the Budapest software company SKAWA Innovation, which has other client apps on its account. She doesn't write code herself; she hired contractors.
How it ranks
Start with the numbers (App Store, 10-28 to 11-06):
| Date | Best Education rank in Hungary | Hungary overall Top Grossing | Score |
|---|---|---|---|
| 10-28 | Top Free 85 | – | 21 |
| 10-30 | Top Grossing 49 | – | 22 |
| 11-04 | Top Grossing 52 | – | 23 |
| 11-05 | Top Grossing 59 | – | 23 |
| 11-06 | Top Grossing 12 | 192 | 24 |
In 10 days the rating count rose by only 3, with an average of 5.0 and not a single written review. That points to small downloads and a high share of paying users, who pay monthly. 11-06 The top 25 on Hungary's Education Top Grossing are nearly all global apps like Duolingo, Praktika, and Knowunity, with only a driving-test quiz app as the local exception. The chart has a low bar, so a few hundred monthly subscribers is probably enough to reach the top 15 (inferred). The same day it also reached #155 on Austria's Education Top Grossing. Austria has many Hungarian-speaking nail techs, and a local shop sells Hungarian-language nail online courses, so these users are likely Hungarian speakers too (inferred).
From 6 it went from #59 to #12; the cause is unverified. It may be that the early September launch members hit their second renewal, or that the individual video and Christmas masterclass sales just went live.
Where the paying users came from
First, existing members. Before the app, she had been selling subscriptions online for years: her own website Be The Best has a Pro/VIP video library at 8 900 Ft/month, plus a Facebook private group; Patreon also had a 6 500 Ft/month membership. The Patreon page now shows as deleted, and the app's VIP price is 8 990 Ft, nearly the same as the old Be The Best price. Existing members moved over without paying more and gained AI and the calendar. It has not been verified whether members all moved over in one batch, or whether Be The Best is still selling at the same time.
Second, her own social accounts. Her personal TikTok has 22.7k followers, the brand account @nailvana_hun has 4 200 followers, plus a Facebook page and a "Marton Bettina course" group. In 10 October, two TikTok accounts posted "Próbáld ki INGYEN a Nailvana APP-ot!" (Try the Nailvana app for FREE!) on the same day: one with 29k views, labeled by herself as "sponsored content," and another with 14k views.
Giveaways at launch. On 3 September, a Facebook giveaway post asked people to tag two nail-tech friends in the comments and sign up for a weekend online launch event, bringing peers in through existing users.
Launch new products in the app too. Sep 26: the autumn new line debuts first in a live VIP stream inside the app. Oct 16: the brand account posts a video saying "Tomorrow at 10 o'clock, the limited cat-eye collection launches in the Nailvana app and online store at the same time." The nail techs who buy her gel polish are the app's users, so selling products and selling content feed each other.
No paid advertising was found, though it can't be ruled out. English media and X have no coverage of it; only people in Hungary's nail community know about it.
Who is doing something similar
In Hungarian, the only app found that combines professional training, AI Q&A, and a work calendar in one place is this one. The surrounding landscape:
| Approach | Examples | How it differs |
|---|---|---|
| Brand academy | Perfect Nails Online Academy | A leading Hungarian nail brand selling recorded courses and certificates, without AI Q&A or work tools |
| Materials brand app | Crystal Nails (launched 2020) | An online store, not a content subscription |
| English professional communities | Nail Career Education, The Nail Tech Org | English courses and communities, with no app or AI tools, and no overlap with the Hungarian-language market |
| AI design images | AI Nail Generator and similar | Give clients design pictures, don't teach the craft |
| Booking tools | Booksy, Fresha | Booking only; the calendar in Nailvana is just an add-on |
| General AI | ChatGPT | Can answer nail questions, but has no champion's backing, doesn't answer from her materials, and has no human expert fallback |
There are differences, but it didn't take off because of them. The main thing is her name and the paying members she already had. The same features from an unknown person launched in Hungary probably wouldn't go anywhere. The AI's role was to make the app worth more than Patreon, support the Pro and VIP price tiers, and give her social accounts something new to promote.
If it were you
C There's a clear playbook to learn here, but it doesn't pay off if you copy it alone. It relied on a national champion, a membership base built over several years, and a gel polish brand. None of those three can be copied. What's left is building this app for other people like her, and the money in any single market is small.
Who it suits: small teams or indie devs who can build custom apps and do subscriptions and AI Q&A, or creators who already have paying members in a professional niche.
Who it doesn't suit: people who want to build a generic 'nail tech AI assistant' and launch it to find users. Without a face people trust, professionals won't pay monthly, and ChatGPT already answers general questions.
How to do it: find vertical professional KOLs who already collect monthly fees on Patreon, Kajabi, or closed Facebook groups: nails, lashes, permanent makeup, hairdressing, baking, pet grooming all work, ideally the top tier in a small-language country. Move their members into your app: match the premium price to their existing member price, add AI Q&A trained on their content with human fallback, and bundle a small tool their users need every day (booking, client records, formula calculator). The free tier gives 3 AI questions so people experience the value first. If you can take a revenue share, don't just charge a build fee; the money is in renewals.
How to get users: no paid acquisition. The KOL promotes the 'try the app free' offer personally, and the launch includes a giveaway where people tag two peers. New products and masterclasses debut only inside the app. Education charts in small countries have low entry bars, a few hundred monthly members can get you charted, and the store gives some free exposure, but don't expect it to drive growth.
When to move: there's no hard deadline. But general AI and tools like Booksy are adding professional features, so the window is to claim 'AI taught by a champion' first. Later, it's just a plain calendar.
Signs you got it wrong: ① Nailvana falls out of the Hungary education top 50 by next spring, meaning launch-month renewals couldn't sustain it; ② the KOL's existing members lose more than half within three months of moving into the app, meaning people paid for the person, not the AI and tools; ③ you can't find creators in three professional niches willing to move their members, meaning Patreon already works well enough for them.

Nailvana (iOS id6766294669) research report
Research date 2026-11-06. Data from our appstore library (app_day / chart_rank / app_profile, library coverage from 2026-10-28), Apple lookup API, TikHub, Jina search and page text.
One line
A creator-subscription professional app for nail techs from Hungarian nail champion Marton Bettina's gel polish brand NAILVANA: training video library + livestream replays + AI 'troubleshooting' assistant + AI design images + client/booking calendar. Launched 2026-08-26, with only 24 ratings on iOS, yet charted #12 in Hungary's education Top Grossing and #192 overall Top Grossing.
Verdict
It didn't 'break out' on the App Store. It's an existing creator subscription business that changed containers. Marton Bettina already ran the Be The Best Pro/VIP subscription video library (8 900 Ft/month) and a Patreon (6 500 Ft/month), so she already had a base of paying nail-tech members. In autumn 2026 she moved the members, livestreams, and newly built AI features into her own app, and the Patreon page was discontinued. At launch she used her existing Facebook, TikTok, and Instagram followers and a giveaway. Downloads are small. What got her into the top charts is two things: the Hungarian education chart has a low entry bar, and the users are professionals who pay monthly year-round.
1. Data
| Date | Best education chart rank in HU | chart | HU overall Top Grossing | Score | Version |
|---|---|---|---|---|---|
| 10-28 | 85 | Free | – | 21 | 1.0.106 |
| 10-30 | 49 | Top Grossing | – | 22 | |
| 11-03 | 92 | Top Grossing | – | 23 | 1.0.107 |

(Source: appstore library app_day, 2026-10-28 to 11-06)
- Ratings rose by only 3 in 9 days (21→24), average 5.0, no text reviews in the library. Download volume is very small.
- 11-06 Austria's education Top Grossing also reached #155 (at ratings 0). Austria has many Hungarian-speaking nail techs, and a local shop sells Hungarian-language nail online courses (elitecosmetix.at), so this audience is likely Hungarian speakers, not Austrians.
- 11-06 Hungary's education Top Grossing top 25 is almost entirely global apps like Duolingo, Astra AI, Knowunity, and Praktika; the only local ones are Mr. Kresz (driving test question bank) and Nailvana (source: chart_rank, hu, genre 6017).
- Rank jumps were sharp: 52 → 59 → 12. Apple's release date is 08-26, but the official launch event was the first weekend of September (Facebook Sep 3 giveaway post says 'the app debuts this weekend'). November 5–6 coincides with the second renewal date of the first monthly members, which is an inference; another possibility is that version 1.0.109 just added 'buy individual videos' while pushing a 48-minute Christmas Aquarium masterclass (nailvana.app/learn, one-time purchase). Neither explanation is verified.
- The Android version is hu.nailvana.app (indexed by AppBrain), not in our googleplay library. The web version at nailvana.app also sells subscriptions.
2. Pricing
Source: nailvana.app homepage, App Store description.
- Free: Hibakereső (troubleshooting AI) 3 questions, 3 design images, calendar, free videos; livestreams are live-only.
- Pro 4 990 Ft/month (about €13): 30 AI questions per month, 30 design images (the store description says 50), unlimited livestream replays, all Pro videos, and 3 live expert Q&A sessions per month.
- VIP at 8 990 Ft/month: adds VIP courses, VIP livestreams and early access to new products. For example, the autumn 26 product launch goes live first in the app for VIP livestream viewers (source: nailvana.hu blog).
- Courses and videos can also be bought separately (1.0.109 update notes).
- For comparison: her earlier BTB Pro was 8 900 Ft/month (bethebest.hu), and Patreon was 6 500 Ft/month (Patreon page snapshot). The app's VIP price is roughly the same as the old BTB price, so existing members don't pay more to move over.
3. Competitors
| Name | Where | Timeline | Scale | How it differs from Nailvana |
|---|---|---|---|---|
| Be The Best Pro/VIP (her own) | Website bethebest.hu | A few years ago (exact year unverified) | Paying members unknown | Predecessor: web video library plus a closed Facebook group, no AI, calendar or app |
| NAILVANA Patreon | Web/Patreon | Around 2025 years ago (she said on Instagram that "Nailvana's new streaming platform is live") | Unknown | Shut down (page shows as removed); these members were moved into the app |
| Perfect Nails Online Academy / Perfect Learning | Web | Around 2025 | One of Hungary's biggest nail brands, with OKJ training accreditation | Recorded courses from the brand academy, no AI Q&A or calendar; the selling points are certificates and courses |
| Crystal Nails app | iOS/Android | 2020-03 | Leading Hungarian materials brand | A shop app, does not sell content subscriptions |
| Elite Körmösakadémia, Műkörmös mozi, etc. | Web/YouTube | Already around | Small | Free or single-purchase course videos |
| Nail Career Education(Suzie) | YouTube/web membership | 2010 era | One of the largest English-language nail education channels worldwide | English, teaches the US system, does not overlap with the Hungarian-language market |
| The Nail Tech Org, Nail Tech Collective, etc. | Web membership | 2020 era | Community memberships in the UK and US | English-language community and courses, no app or AI tools |
| AI Nail Generator and various AI nail-design tools | iOS | Since 2024 | A few hundred ratings | Generates design images for consumers; does not teach technique or manage bookings |
| Booksy, Fresha and other booking tools | iOS/web | Already around | Very large | Only handles bookings, no technique content; Nailvana's calendar is only a bundled feature |
| General-purpose AI like ChatGPT | Big-company features | – | Very large | Can answer nail questions, but has no champion backing and does not answer using her products and materials |
Conclusion: in Hungarian, we have only found one app that puts professional nail technician education, AI troubleshooting and a calendar into a single app. Comparable English-market products are community-plus-course models that don't make AI Q&A the main selling point. Most apps in our library with "nail" in the name are children's nail games, which are not the same thing.
4. Where users come from
- Existing paying members moved over (likely, the evidence is indirect): the Patreon page (NailvanaHungary) already reads "This page has been removed"; BTB's original price was 8 900 Ft, the same as the app VIP; the app's livestreams and video library do what BTB and Patreon used to do.
- Founder and brand social accounts (confirmed): TikTok @mbettinanails has 22.7k followers and 152k likes; @nailvana_hun has 4 200 followers; Instagram @nailvana_hun has 4 200+ followers; there are also the Facebook pages bettinanaildesign and nailvanahungary, and the "Marton Bettina Hungarian courses" group. 2026-10-10 Two TikTok accounts posted "free trial of the Nailvana app" on the same day, with 29k and 14k views; one labeled itself "ad content" (source: TikHub). The Instagram bio links to the App Store.
- Launch giveaway (confirmed): 2026-09-03 The Facebook giveaway post required commenters to tag two nail-artist friends and sign up for a weekend online launch event, using existing users to bring in peers.
- Brand tied to product launches (confirmed): new autumn products premiere to VIP livestream viewers in the app first. Nail technicians who buy her gel polish are already the app's target users.
- Offline events and courses (partly confirmed): she runs packed industry events and in-person courses (self-described on nailvana.app), and her Instagram has a Reel from 2026 about an industry day and competition; the specifics were not checked one by one.
- Paid acquisition: none found. Nailvana doesn't show up in x-radar search, and there is no coverage by English media or on X.
5. Why it took off
- People and trust: she has won two Nailympia gold medals (2012 London, 2023 Orlando; nailvana.hu/rolunk links to the official results), has worked in salons since 2009, and says her own NAILVANA material brand has been "leading" for three years (self-reported). Nail technicians trust her as a person, not an app.
- Paying habit already exists: she has sold monthly video subscriptions for years (BTB Pro, Patreon), so launching an app doesn't require educating users to pay from scratch, just collecting payments somewhere new.
- Professional tool, used daily: "while the client is in the chair" you can instantly look up what to do about gel lifting, peeling or allergies, and the calendar keeps each client's nail history. It's a tool that earns money, so willingness to renew is stronger than for consumer apps.
- AI is the added value: the troubleshooting assistant is trained on her team's expertise and can hand off to a live expert in one tap; the design-image tool lets you preview colors on your own photo. This turns her from "selling videos" into "always having a consultant", and it justifies the tiers at 30 and 50 uses per month.
- Small market, low chart bar: the revenue needed to reach #12 on Hungary's education Top Grossing chart is small, and a few hundred paying members may be enough (inference). Global big apps have no Hungarian-language nail content here, so it has no direct competitor.
6. Differentiation
- Compared with global English nail education: it is in Hungarian, features a home-country champion's face, and is directly tied to her own material brand, so its users are already nail technicians who buy her gel polish.
- Compared with local Hungarian brand academies: others sell courses and certificates, while this sells "a consultant in your pocket at work", AI plus live human answers plus a calendar. The aim is for nail technicians to open it every day and renew monthly.
- This difference is only part of the reason. The main factor is still the founder's own followers and old members. Without her name, the same features in a small-language market probably wouldn't take off. The AI features help the app justify a higher price than Patreon and allow tiered pricing, and they give her social media promotion something to talk about.
7. How many people know about it / is anyone copying it
- No media coverage found and no public revenue figures; nothing on X or in English-language web. Only people in the Hungarian nail community know about it.
- Copycats: none found. Other Hungarian material brands (Perfect Nails, Crystal Nails) are still stuck with online courses and shop apps.
8. What others can learn
- "Vertical professional KOL, plus their existing video membership, plus AI Q&A, built into their own app": professional creators already collecting monthly fees on Patreon or Kajabi (nails, lashes, tattoo/permanent makeup, hairdressing, baking, pet grooming) can move members into an app, use AI plus live human answers and professional tools (calendar, client records) to raise the average order value, and then use low-barrier charts in small languages and small countries to win app store exposure.
- Pricing reference: set the new app's premium tier at the same price as the old membership so existing members don't pay more when they move over; give 3 free AI questions on the free tier to drive conversion.
- Launch new products in the app for VIPs first, so selling materials and selling content boost each other.
- Development was outsourced to the Budapest software firm SKAWA Innovation (parent company of the Easyling website translation platform, which has several client apps on its account), a realistic route for creators without a tech team.
9. Still unclear
- How many paying members there are, and whether BTB members actually all moved over; the BTB website still sells subscriptions, so whether both are being sold at once is unclear.
- What drove 11-06 to #12: renewal dates, separate course purchases, or a single livestream event.
- Share of Android and web usage (no Android data in our library).
- Whether there is paid acquisition (Meta Ad Library not checked; our ad library only tracks products on our list).
