Cairn is an on-device desk-wellness coach for macOS. It uses your webcam and Google's MediaPipe AI — running entirely on your Mac — to watch your posture, blink rate, and screen distance, then gently nudges you before the slouch, dry eyes, or 3pm slump set in. When you've been sitting too long, Cairn stands you up and runs a guided Stretch Coach that uses live pose tracking to check your form and score your range of motion. There's also a 5-minute Desk Meditation with an on-device ambient soundscape, and a daily Wellness Score to keep your streak. Best of all, it's private by architecture. Your camera frames are analyzed in memory and never saved, never uploaded, never seen by anyone. No account, no cloud — it works fully offline. Free to download (real-time nudges + a 20-20-20 timer). Cairn Pro — founding price $14, then $25, one-time, no subscription — unlocks the AI Stretch Coach, Desk Meditation, and Insights & History.
