How it works

Records only when there is sound

Tap Start sleep before bed. Murmur listens quietly and saves a clip only when it hears sleep talk, snoring or other sounds — including the few seconds just before the sound started.

Night-by-night timeline

Each night gets its own timeline with a sound graph. Play clips, mark favorites and delete what you don’t need.

Schedules

Set repeating or one-time schedules. Android doesn’t let apps turn on the microphone by themselves, so Murmur sends a reminder before each schedule — tap it once and recording starts on time.

Works with the screen off

Turn the screen off and recording continues. When the night ends, a summary notification tells you how many clips were recorded. You can turn it off.

Private by design

Murmur has no internet permission. Recordings are kept in the app’s private storage and are not included in cloud backups. Uninstalling the app deletes them.

Free and Pro

Listening to your sleep talk stays free. Pro is for keeping more, taking recordings out of the app and fine-tuning.

Questions

Does Murmur upload my recordings?

No. Murmur has no internet permission, so it cannot send anything over the network. Recordings stay in the app’s private storage on your phone.

Is Pro a subscription?

No. Pro is a one-time purchase through Google Play.

Why do scheduled recordings need a tap?

Android doesn’t let apps turn on the microphone by themselves in the background. Murmur sends a reminder before each schedule; tap it once and recording starts at the scheduled time.

What happens to my recordings if I uninstall?

They are deleted with the app. They are not included in cloud backups, so if you want to keep some, export them first (Pro).
