Description by QR LLC (from the App Store)

OS3 is a voice assistant built for Apple Watch. Talk to it like you would a friend, no tapping, no typing, just your voice.

How it works:
1. Raise your wrist and start talking. OS3 listens, thinks, and responds out loud entirely hands-free.
2. Conversations feel natural with real-time voice powered by Google's Gemini AI.
3. Live captions appear on screen as you speak and as OS3 responds.

Features:
1. Voice first interaction designed for the small screen, concise answers, no clutter.
2. Conversation history: revisit past conversations and pick up where you left off.
3. A visual orb that animates as OS3 listens and speaks.
4. iOS companion app for managing your account, viewing usage, and subscription details.
5. Sign in with Apple for quick, private authentication.

OS3 requires an active internet connection on Apple Watch. An iPhone with the companion app installed is needed for account setup.
