Meeting notes that never need the internet. LangLang records conversations on your iPhone or Apple Watch, transcribes them on the device and shows who promised what, every line linked back to the original audio. No account required. Apple Watch is optional. Private by design • Works even in Airplane Mode: recording, transcription, Cantonese in writing, finding who promised what, and reminders. • No account and no sign-in. • Processing is on-device by default. No LangLang server ever receives your conversations. • No third-party analytics or tracking SDKs. Our App Store privacy label: Data Not Collected. • If you connect your calendar, it is read only on this iPhone. Optional enhanced transcription needs an initial download from Apple. If you enable your own AI provider key, text is sent to that provider. Exporting or sharing sends the data you choose to your chosen destination. Cantonese, in writing Switch a Cantonese transcript between spoken and written Chinese with one tap. English inside a sentence stays as it was said. Tap any line to hear it from the start, and export either version. Who promised what, and a reminder at the right time • Promises and deadlines come with the original words. • Tap Remind me and choose when: as agreed, in an hour, tonight or tomorrow morning. On iOS 26.1 or later it can ring like an alarm. • When it is due, LangLang asks whether you did it, so open promises don't quietly slip. Before you meet Connect your calendar and, a few hours before you meet someone you have named, LangLang shows what you discussed last time and what is still open. Meeting minutes One tap turns a recording into one page of minutes: attendees, who will do what and when, and key points where your iPhone makes them. Copy it or share it as text; your first PDF and Word minutes are on us, and LangLang+ covers every meeting after that. How it works • Start recording on your iPhone or Watch. Stop when you are done. • Read the transcript and return to the audio to check a detail. • Review key points and commitments with links to their source sentences. • Name people you recognize and revisit their past conversations. English, Mandarin and Cantonese For conversations in these languages, including mixed-language meetings. Background noise and overlapping speech can affect transcription and speaker labels. Check important names, dates and amounts against the recording. Take your history with you Export audio, transcripts and voice profiles in a backup file, then restore it on a fresh installation on your next iPhone. Keep backups somewhere private. Free and LangLang+ Free includes unlimited recording, transcription and playback, naming people, search across your recordings, complete key points for the first three conversations that produce them (then the top point of each), and export of all your data. LangLang+ adds complete key points and possible next steps for every conversation, each linked to the original words, plus memory across recordings: what is still open with someone, brought back when you meet again. Choose a monthly or yearly subscription, or a one-time lifetime purchase. A separate single-conversation purchase unlocks that conversation's complete key points; it does not include LangLang+. Subscriptions renew automatically unless canceled at least 24 hours before the end of the current period. Your Apple Account is charged at purchase confirmation, or after an eligible trial ends. Manage or cancel subscriptions in Settings > Apple Account > Subscriptions. Lifetime is a one-time purchase, not a renewing subscription. See the app for current prices and any trial eligibility. Let other participants know when you record, and follow local recording laws. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
