The first anti-doomscrolling app powered by on-device Edge AI. Adaptive friction. True hardware grayscale. No cloud. No compromise.
Tethr monitors usage strictly on your device. The ML model learns your scrolling patterns and sets a personalized trigger. Relapse more? Your time limit shrinks automatically.
Three-tier system: a subtle timer pill first, then your screen locks into true grayscale, then cognitive friction - a math quiz you must solve to keep scrolling. No easy exits.
We don't draw a gray box over your screen. Tethr uses an ADB-granted secure setting to kill color at the hardware level. Swipe-proof. Truly inescapable.
Accessibility service and a one-time ADB command. Everything runs locally after that - zero servers involved.
Tethr observes your scrolling sessions. The model maps your average session length to a personalized trigger window.
When you hit your trigger: pill, then grayscale, then math quiz. Each tier is harder to dismiss. By design.
The AI notes your real session length and your next trigger time drops. The system learns against you.
