iPhone
Real-time simultaneous interpretation, completely offline. NoNetPlay translates live conversations as you speak — your voice never leaves your iPhone, even when you're 30,000 feet up.
Unlike apps that need to download language packs every time you want a new language, NoNetPlay's entire AI translation engine lives on your iPhone. Once installed, you don't need WiFi. Ever.
Simultaneous Translation — 15+ Language Pairs
• English ↔ Chinese, Japanese, Korean, Spanish, French, German, Portuguese, Italian, Russian, Arabic, and more
• Speak in one language, hear it in another — automatic language detection
• Voice recognition + AI translation engine, both run entirely on-device
• Sentence-by-sentence output with synchronized voice playback — no waiting
AI Chat
• Built-in offline AI assistant for free-form conversations
• Switch between different on-device AI options mid-conversation
• Real-time output, word by word as it generates
Privacy First
• Every word stays on your iPhone — no servers, no cloud, no logs
• No account, no login, no subscription pressure — just open and use
Offline AI Download Manager
Built-in download manager with multiple sources (domestic mirrors prioritized for users in mainland China). Resume on interruption supported. Available offline AI options:
