Which language is being spoken right now? WhichLang listens through your microphone and shows you in real time which language is spoken around you – with its confidence, for over 90 languages. Just open the app and it starts. No tapping, no setup, no sign-up. • IDENTIFIES OVER 90 LANGUAGES From German, English, Russian and Turkish to Ukrainian, Arabic, Chinese, Japanese and many more. WhichLang shows the three most likely languages with a percentage – great for gauging certainty even between similar languages. • COMPLETELY OFFLINE All recognition runs on your device. No audio ever leaves your iPhone, and the app works without internet – on a plane, on the subway, abroad. • PRIVACY FIRST Audio is never recorded, stored, or transmitted. The microphone is only active while the app is open. No account, no ads, no tracking. • LIVE DISPLAY A level visualization shows you that WhichLang is listening, and results update smoothly as people speak. • HISTORY (optional) If you like, WhichLang remembers which languages were detected and when – the result only, never audio. Deletable anytime, stays local on your device. Perfect for travelers, language lovers, people in multilingual settings, and anyone who ever wondered: "What language is that?" WhichLang is free and contains no ads.
