Murmel

What you mumble in your sleep.

Murmel listens at night whenever something happens, recognises the sound on your iPhone and writes down what you say in your sleep.

One night, captured

Murmel does not record the whole night, only the moments when there is something to hear. In the morning they are waiting for you, in order.

  1. Movement4 seconds
  2. Cough3 seconds
  3. TalkingNot the blue one, the other bag.
  4. Laughter2 seconds
  5. TalkingYes. Tomorrow then.

An example night. Talking, coughing, laughing, sighing, crying, teeth grinding, movement, footsteps and alarms start a recording. Snoring and steady breathing deliberately do not.

What happens at night stays with you

Recognised on your iPhone
Sound recognition and transcription run on the device. No audio is sent to a server for it.
Complete without an account
Murmel works without signing in. An account is optional and only used for backup.
Encrypted when you back up
If you choose nights for the cloud, your iPhone encrypts them first. Only you can read them.

How Murmel handles data

Put your iPhone on the nightstand. The morning will tell you the rest.
