TransPeek is an iOS app that delivers real-time screen translation through a floating subtitle window. Unlike traditional translation apps that force you to switch back and forth, TransPeek uses iOS ReplayKit screen broadcast and Picture-in-Picture (PiP) technology to overlay translations directly on top of whatever you're doing — gaming, watching videos, browsing foreign websites, or reading documents. Powered by Apple Vision framework for 100% on-device OCR, your screen content never leaves your device. Just tap Start, select the broadcast, switch to any app, and read translations in a floating window that follows you everywhere. At 13 MB and a one-time $4.99 unlock, TransPeek is the lightest, most private screen translator on the App Store.
A Picture-in-Picture window floats above any app, displaying recognized text and translations in real time. Resize it, drag it anywhere on screen, or minimize it — the subtitle window follows you across every app without interruption.
Powered by Apple Vision framework, all text recognition happens entirely on your device. No screenshots uploaded, no cloud processing, no data collection. Your screen content stays private — period.
Games, live streams, Safari, social media, PDFs, foreign-language apps — TransPeek translates whatever is on your screen. It uses iOS screen broadcast, so it works universally without per-app integration.
TransPeek intelligently filters out noise — status bar icons, timestamps, UI chrome — and focuses on the meaningful text: dialogue, articles, captions, and content you actually want translated.
On supported iPhones, the Dynamic Island shows live translation status. Long-press to quickly pause, resume, switch languages, or stop the translation session without leaving your current app.
Every translation session is saved with full text. Review past translations, track your weekly usage stats, and see language pair breakdowns — all in a clean dashboard.
Just 13 MB — 10x smaller than competitors. Free to try, $4.99 one-time purchase to unlock unlimited use. No subscriptions, no hidden fees, no ads.
Open TransPeek, choose your language pair, and tap "Start Translation". Select TransPeek from the screen broadcast popup — a floating subtitle window appears.
Go to any app — a game, video, website, or document. TransPeek runs in the background via screen broadcast, continuously reading your screen with on-device OCR.
The floating PiP window shows translated text in real time. Drag it where you like, resize it, or tap the Dynamic Island for quick controls. Your workflow stays uninterrupted.
