CrystalNest per Linda

Monitors mouse movement, keyboard activity and tab focus patterns to estimate your current concentration level, then intelligently lengthens or shortens Pomodoro-style work and break intervals. Optional binaural-beat audio adapts to your detected state, helping you enter and maintain deep focus more easily. All activity analysis remains strictly local so your working habits never leave the device. No browsing data or biometric signals ever leave your device.
