Recording fails
Check microphone permission, other apps using audio, battery/storage and system power settings. A changed input route requires starting again from the foreground app. Devices without compatible input or AAC support show an error; text-only memos remain available.
Monitoring and pre-roll
Pre-roll contains only audio actually captured while the foreground meter was running. Start monitoring from the app and stop from its screen or notification. It does not restart automatically after forced termination.
Levels differ from a sound-level meter
dBFS describes digital microphone input, not absolute sound pressure. Reference calibration remains device-dependent and is not certified or A-weighted.
Restore Plus
Use the Google account that purchased Plus and select Restore purchases. Pending transactions do not enable Plus until verified. iOS purchases do not transfer.
Independent sample
Open Settings → Data → Open sample, or use the onboarding sample entry. Exiting returns to normal data. Deletion requires a separate normal-data confirmation.
Widgets and shortcuts
The home widget shows today and seven-day counts. App-icon shortcuts open recording, monitoring or a memo. The Quick Settings tile opens the app before recording starts.
