Download ErgoSense — free for Mac, Windows & Linux

ErgoSense watches your posture and eye strain through your webcam and nudges you when you slouch. Every frame is analysed on your own machine — nothing is uploaded, recorded, or stored.

Why ErgoSense is free

Most desktop posture apps charge between $24 and $100 a year. ErgoSense was built by a solo developer who thinks a tool that protects your spine and your eyesight should not sit behind a paywall. There is no premium tier, no trial timer, and no upsell.

  • No account or sign-up required
  • No subscription, ever
  • No telemetry on your health data
  • Your webcam feed never leaves your device
