About Nocterrain
Nocterrain maps overnight relative sound energy into a private on-device acoustic terrain. Start a night session to review retained event clips. Compare nights and run room-condition experiments to understand how your sleep environment changes over time. Nocterrain works without an account and keeps its acoustic history focused on your device.
