Quick note from the dev side: I'm an indie Android developer, and this post is more about the business model than the code — why I shipped my screen translator as a one-time purchase in a category that runs on subscriptions. Originally published on my Medium; sharing it here for the dev community's take.
You're three chapters into a manga that never got an official translation. The raw is right there on your screen — Japanese, untranslated, and the fan translation is six months behind.
So you do what everyone does: you search Google Play for a screen translator. And you find the same deal repeated a dozen times. Free to install. Ads everywhere. And the moment you actually want to use the thing, a paywall: weekly plans, monthly plans, "premium" tiers topping out at $59.99, $99.99 a year to translate text on your own phone.
I build Android apps. When I needed a screen translator for manga and games, I went looking for the one I'd pay for once and own. It didn't exist. So I built it.
First, an honest tour of your options
The built-ins. Google Translate is a camera tool at heart — brilliant at menus and street signs, but to translate a game dialog box you screenshot, leave the game, paste, and come back. Samsung's on-screen translation is genuinely good, but it only exists on recent Galaxy flagships. Apple's Translate has no real-time overlay at all.
The big "free" apps. This is where most people land, and where the meter starts running:
| App | Installs | The catch |
|---|---|---|
| Translate On Screen (EZ) | 10M+ | Ads, in-app purchases up to $59.99 |
| Instant Translate On Screen (Sapiens Labs) | 5M+ | Ads, in-app purchases up to $59.99 |
| Game Translate Master | 1M+ | Ads, in-app purchases up to $99.99 |
| Gaminik | 500K+ | In-app purchases up to $59.99 |
| Screen Translate (YoyoDev) | 50K+ | In-app purchases up to $14.99 |
None of these numbers come from a hit piece — they're printed on each app's own store page. "Free" here means the download is free. The translation is rented.
Even the privacy-first newcomers do it. Traverba markets itself as the complete on-device alternative — and charges $1.99 a month, forever, for its premium tier. At that rate you pass $4.99 in the third month and keep paying.
The subscription math nobody does. A $4.99/month plan is $60 a year, every year, for as long as you read manga. Over three years that's $180 for a tool whose core job — read pixels, translate text — your phone already does locally.
What I built instead
Screen Translate: Manga, Games is a screen translator with a business model from 2010:
- $4.99, once. No subscription. No ads. No "premium" tier waiting behind the features you actually need. You pay less than one month of the big apps' plans, and you're done.
- An on-device engine. Translation runs on your phone, offline. Your manga pages, game chats, and messages never leave the device — there's no server collecting what you read. An AI engine is there when you want more natural phrasing and have a connection.
- Built for manga and games specifically. Overlay translation that sits on top of the original panel, plus auto-scroll for webtoons and long strips — the two reading formats generic translators handle worst.
- 50+ languages, aimed at the JP/KR/CN → English direction most scanlation readers actually need.
That's the whole pitch. It does one thing, it does it without a cloud account or a recurring bill, and the price is the price.
The free version, because "trust me" isn't a business model either
If you'd rather try before paying $4.99: Screen Translator Lite is the same translator, free for 5 translations a day, no ads, with a one-time $2.99 unlock if you outgrow the free tier. No subscription there either. (Yes, maintaining two apps with no recurring revenue is exactly as lucrative as it sounds.)
Who this is for
- You read raw manga or webtoons and machine translation is good enough to follow the story
- You play Japanese/Korean/Chinese mobile games that never got a global release
- You're tired of every utility on your phone quietly becoming a monthly bill
It's not for everyone. If you need a camera translator, a voice interpreter, and a document scanner in one app, the suites exist — they'll just charge you rent.
I wanted software you buy. So that's what I sell.
Screen Translate: Manga, Games — $4.99 one-time on Google Play.
Screen Translator Lite — free, same store.
