SyncTrans: Live Translator — App Store rankings

About this app

The developer's US App Store description, in full.

SyncTrans is a live interpreter powered by two engines: on-device models and the cloud. Speak in your language — the translation appears on screen instantly and can be read aloud right away. One machine, many languages, real conversation. Made for real moments • Professional meetings: foreign-language speech translated live on screen, minutes exported afterwards • Client conversations & hosting: two screens, one language each — as natural as talking to a friend • Medical visits, legal consultations and other private matters: switch to on-device mode and nothing leaves your machine • Travel & sightseeing: shops, attractions, directions — like carrying your own guide Cloud: ready in seconds Sign up and start translating immediately — zero setup, zero learning curve. Fast recognition, natural translations. Sign-up includes free cloud time; after that you're billed by the spoken minute, remaining minutes always visible, with plans to match your usage. Your conversation history stays on your machine — our servers keep usage records for billing, never the content. On-device: 100% private Speech recognition, translation, and read-aloud all run on your own machine. Your voice and your words are never uploaded anywhere. When you first enable it, the app downloads the AI models inside the app (with visible progress) — after that, everything happens locally. One small one-time purchase unlocks it forever. On-device mode runs on your own hardware: it needs Apple silicon, and memory sets the tier — light from 16 GB, balanced 24 GB, top quality 48 GB. More memory, smoother runs. Self-hosted AI: your data on your servers Machine not powerful enough for on-device models? The same local unlock also lets you connect your own AI service: point the app at your own model server or API key (compatible with mainstream AI-service APIs), and translations run through your infrastructure, never through our cloud. Highlights • Three layouts: chat, split view, and meeting minutes — switch to fit the moment • Dual-screen mode: one language full-screen on each display, perfect for face-to-face conversation • Left/right ear translation: share one pair of headphones — each person hears only their own language • Project-based history: every turn saved automatically, searchable, exportable as TXT, Markdown, or SRT subtitles • Auto read-aloud the moment each translation finishes • Glossary: names and technical terms translated consistently • Context-aware translation that follows the conversation • Interface in 7 languages: English, 中文, 日本語, 한국어, Español, Français, Українська Start in three steps 1. Open SyncTrans and pick cloud, on-device, or self-hosted 2. Choose the languages you and your partner speak 3. Press start and just talk Our privacy promise With the on-device plan, no audio and no text ever leaves your machine. In cloud mode, our servers record usage for billing and never store your conversations — history lives only on your machine. FAQ Q: Is it a subscription? A: The cloud membership is an auto-renewing subscription with several tiers; each period it adds cloud translation minutes, and minutes you don't use stay valid through the next period. On-device is a one-time purchase, not a subscription, and it also unlocks self-hosted AI. Q: Do I need to stay online? A: Cloud needs a connection, and self-hosted AI needs to reach your own server. On-device mode runs entirely offline once the models are downloaded. Languages Recognition and translation across multiple languages, centered on Chinese, English, and Japanese. Questions or ideas?
