"I thought it was Higgsfield": how a Korean developer sold weekly subscriptions on the store under someone else's name

The Korean App Store and Google Play have an app called 힉스필드 Video AI. 힉스필드 is the Korean spelling of Higgsfield, and Higgsfield itself has no mobile app. A solo developer in Seoul took the name. In just over two months it reached roughly 20K installs and ranked #20 or so on Korea's Utilities grossing chart. Below: how it works, where the money comes from, why you shouldn't copy it, and which part of this playbook you can legitimately take.

A 1-star review

In Oct 29, a Korean App Store user gave it a 1-star review titled "이거 진짜 최악이네요" (this is seriously the worst), with a single line of text:

I tapped subscribe thinking it was Higgsfield, my bad ㅠㅠ please refund me (힉스필드인줄 알고 구독 누른 내가 잘못이지 ㅠㅠ 환불해주세요 제발)

It's not an isolated case. In Oct 18 someone wrote "내가 알던 힉스필드도 아니고" (it's not even the Higgsfield I know), in Oct 21 "제가알던 힉스필드가 아니네요" (not the Higgsfield I knew, I didn't use a single credit, please refund), in Oct 23 the title was simply "보이스피싱 같네요" (feels like a phishing scam) with the body "가짜 힉스필드" (fake Higgsfield), and in Nov 3 "짝퉁인가" (is this a knockoff?). When replying to these reviews, the developer opens with "안녕하세요, 힉스필드 AI 팀입니다" (Hello, this is the Higgsfield AI team).

Its iOS average rating is 2.4 (45 ratings, Korean App Store, 11-06). Of its last 15 reviews, 13 are 1 stars. Yet it sat on the Korean "Photo & Video" grossing chart, and from Oct 28 to Nov 6 it ranked between #23 and #29 every day.

What it is

The store title is "힉스필드 Video AI - 바이럴 영상을 내꺼로" (turn viral videos into yours). The English name on Play is Highfield AI Video Generator, just a few letters off from Higgsfield. The first line of the Korean Play description reads "힉스필드는 사진 한 장으로 바이럴 숏폼 동영상을 만드는 AI 영상 생성기예요" (Higgsfield is an AI video generator that makes viral short-form videos from a single photo).

The feature set is simple: pick a template pulled from viral videos (travel, fancam, pets, "quiet luxury" style, award ceremony, product ads for whatever you're selling), upload a selfie, and get a vertical video in a few minutes with no prompt writing. Pro is a weekly subscription that grants credits each week.

On Android it launched in Sep 13, on iOS in Sep 18, and only in Korea. On Play the developer is listed as Thing Apps (띵앱스, a solo business in Yongsan, Seoul). On iOS it's credited to Dongwon Ahn. Several versions shipped from Nov 3 to 6, and it's still being updated.

Where the traffic comes from: people searching the store for "힉스필드"

The demand was built by Higgsfield itself, with paid spend. It worked with the Korean agency Feed Media to seed Instagram magazine accounts, AI creators, and prompt-sharing posts across Korea. Monthly searches for "힉스필드" on Naver went from 2025 in November 6,200 to 2026 in July 76,400 (feedmedia.io, 7-27). A co-founder said on LinkedIn that Korea is already Higgsfield's second-largest market worldwide. The most popular use in Korea is "Viral Presets": upload a photo, get a viral video, and Naver has ready-made tutorials.

But Higgsfield's official help page is explicit: there is no mobile app and no desktop app, only the web. A Reddit user asked "Does Higgsfield have a good mobile app?" and the reply was "the ones in the store are all fake."

Then a Korean user who'd been hyped on Higgsfield pulls out their phone, searches the store for 「힉스필드」, and this app comes up. It does three things: it squats the Korean transliteration of the brand name; its subtitle names the feature that's hottest for Higgsfield in Korea; and its English name is a near-miss, Highfield.

The other route in is Instagram. A comment from Oct 22 reads 「인플루언서가 올린 귀여운 AI영상 프롬프트 나눔 글에서 이 앱을 이용하라고 해서 다운함」 (an influencer's cute AI video prompt-sharing post told people to use this app, so I downloaded it). Whether an influencer promoted Higgsfield and the user got the wrong app, or the developer paid the influencer, we can't tell (unverified). We found no ads for it in Meta's public ad library.

On the numbers: Play lifetime installs went from Oct 29 9,628 to Nov 6 19,873, doubling in a week (public Google Play install counts). But in the Korea Tools free chart it slid from #94 to #197, so new installs are slowing.

Where the money comes from: subscriptions in the week after the mix-up

Weekly subscription 24,900 KRW (about $18). One reviewer did the math: "다른 어플 주에 6600원인데 이건 24900원" (other apps are 6,600 KRW a week, this one is 24,900), and "Too expensive for what it does. I thought it would work better for the price. It only lets you do 2 items, not 3, and it can't recognize photos well, and there's no preview." The in-app purchases on Google Play are listed at $16.99 to $54.99 each.

The paywall sits before any output, so the money arrives before users realize this isn't Higgsfield. The negative reviews are full of 「退款」「取消订阅」「出来的是别人的脸」「模板没几个」 (refund, cancel subscription, the output is someone else's face, not many templates), so retention is probably poor (inferred). It held a top-#19 spot in the Korea Tools Top Grossing chart, falling to #26, and it's the high price that keeps it there: that chart isn't hard to reach, and a $18 weekly subscription only needs a modest number of buyers to rank in the top 30. Real revenue and refund rates aren't visible from outside.

This developer has done it before. Their earlier app 「나노 바나나」 rode the Google Nano Banana name, got 225k installs on Play, and reached #34 to #35 in Korea's Lifestyle Top Grossing. Before that, they made the Instagram repost tool 멀티 리그램 (1.36M installs on Play). So this is someone who builds for Korean Instagram users and chases overseas AI buzzwords, and this is the same playbook working a second time.

Who it's competing with

There's no product difference. The whole market is doing 'one photo + template → video.' What it does own is a position: the Korean store, the Korean name 「힉스필드」, and mobile.

how many people know it

No press coverage of this app, nothing on X, and no disclosed revenue. But the 'fake Higgsfield app' problem has been called out: there's a Reddit thread, 'Fake Higgsfield AI apps on the Google Play Store,' and Higgsfield's official site has a help page listing its official platforms. The playbook is widely known and plenty of people are copying it. Only this one has held the Korean-localized position so far.

If it were you

Bottom line: Don't copy it. It earns from users who mistake it for the real thing. A trademark complaint or a store impersonation review could take it down, and refunds and bad reviews are rising alongside. What's worth taking is how to spot the gap: a foreign AI brand has taken off in one country, but the local app stores are empty.

Good fit for: Small teams that know a non-English market well (Korea, Japan, Germany, Brazil...) including its stores and social platforms, who already have an AI generation backend and can ship a single-use-case app within a week.

Not for: Anyone aiming for a durable product. Apps like this have their lifespan set by someone else: the day the official brand ships an app or files a complaint, the traffic is gone. Also not for anyone unwilling to take on store policy risk.

How to do it: Watch AI brands whose search volume spikes in one country while they have only a website or no local-language app. Find the specific use case that's hottest there (here, 「one photo → viral video」), build only that one, and explain it clearly in the local language. Name it with a category term such as 「바이럴 AI 영상」 or 「사진 한 장 영상」, not the competitor's trademark. Put the paywall before output, sell a weekly subscription, but give a free preview that shows real results so refunds stay down.

How to get users: Category keyword search in the store, plus local Instagram and TikTok prompt-sharing posts and influencer partnerships, to catch the same people who were hyped. You won't get the brand-name traffic, so content has to make up the difference.

When to move: The window follows the buzzword. From an AI brand catching on in one country to its official app launch is usually a few months. Higgsfield has been hot in Korea for over half a year, so this wave is late. What to look for is the next one.

Signs you've misread it: If its traffic dies once it's removed or renamed, the business ran entirely on the brand name, and a category-term version of the same thing won't capture demand. If Higgsfield ships an official app and this one's traffic holds, users actually wanted 'local language + no prompts + one-tap video on mobile,' and that use case is worth building.
