Gesture Mute

Innovative gesture recognition app that mutes your microphone with a simple hand gesture during calls.

Gesture Mute

Challenges

  • Training a lightweight hand gesture model that runs in real-time on mobile devices without draining battery
  • Distinguishing the mute gesture from natural hand movements during a call
  • Integrating with system audio APIs across Android and iOS to control microphone state

Features

Real-time hand gesture recognition using TensorFlow Lite on device
Automatic microphone mute/unmute when the gesture is detected
Customizable gesture mapping (choose which hand signal triggers mute)
Low battery impact with efficient on-device ML processing
Works across all calling apps (Zoom, WhatsApp, Telegram, phone calls)

Technical Highlights

  • Runs at 30fps on mid-range Android devices
  • Model size under 5MB for fast download
  • Battery impact less than 2% per hour of call time

Impact

Featured on Product Hunt, 500+ downloads in the first week with 4.5-star average rating.
