What people do today

Ideas a builder, maker or community group could start on:

A diagnostic tool within the app that verifies microphone and sensor functionality before starting a sleep session
A community-driven compatibility database where users report specific hardware/OS combinations that fail to track sleep
An automated alert system that notifies users if the app detects no movement or audio data after 30 minutes of a session

“it’s still nothing but straight line on the sleep graph”
