Polygotcha
Read full descriptionHide full description
PolyGotcha is a keyboard that translates as you type. Write in your own language, pause, and the translation appears right above the keys. Tap it to swap your text before you hit send. It works everywhere you type: Messages, WhatsApp, Instagram, Mail, dating apps, anywhere. No copying, no pasting, no switching to a translator app and back. HOW IT WORKS 1. Type in your language. 2. Pause for a moment. The translation appears in the bar above the keys. 3. Tap it to replace your text, or turn on automatic mode and just type. Two-way translation reads what you typed and picks the direction on its own. Reply to a French message in English and send it in French; when you type French, it turns into English. WORKS ON ANY IPHONE Two on-device models. Apple Intelligence handles nuance and tone on iPhone 15 Pro and later. Apple Translation runs on every other iPhone, so an older device is not locked out. PICK YOUR TONE Neutral, casual, formal, or street. Street tone writes the way people actually text, with everyday slang instead of textbook phrasing. Tone is available on the Apple Intelligence model. PRIVATE BY DESIGN Translation runs entirely on your iPhone. Your words never leave your device: no servers, no accounts, no tracking. PolyGotcha has no backend to send them to. Full Access is optional and off by default. Leave it off and iOS itself keeps the keyboard off the network. Turn it on only if you choose the Apple Translation model, which iOS will not open to a keyboard otherwise. It is still on-device translation either way. LANGUAGES Translate between English, French, Spanish, Portuguese, German, Italian, Japanese, Korean, Chinese, and more. The exact list depends on your device and iOS version. FREE AND PRO Typing with the PolyGotcha keyboard is free, always, and so are your first 10 translations. After that Pro unlocks unlimited translation: 7 days free, then $1.99 a month, $11.99 a year, or $24.99 once for lifetime access. GOOD TO KNOW PolyGotcha needs iOS 26 or later. The Apple Intelligence model also needs an Apple Intelligence device (iPhone 15 Pro or newer); on any other iPhone, choose Apple Translation in the app's Settings tab. Translations come from on-device AI models, which can make mistakes, so double-check important messages.

Verdict
The clearest difference is update cadence: Polygotcha at every 2 days against KeyLingo's every 4 weeks. KeyLingo's advantage is iOS requirement (16.0 vs 26.0). On price, ads, in-app purchases and device support there is nothing between them.
