Murmur is a voice journal for iPhone. Tap once and talk, and it writes down every word on your device. There is no account, no cloud and no analysis of what you say. It works in airplane mode.
Use it on a walk, at the end of the day, or whenever something needs saying. Your words appear as you speak.
The app has no networking code. Speech is transcribed on the device. If on-device recognition is not available, Murmur will not record rather than use a server.
There are no mood charts and no AI summaries of your life. It keeps what you said.
Share an entry as Markdown or plain text, or export many at once.
Yes. On iOS 26 it can use Apple's on-device speech model. On earlier versions it uses offline dictation, which you turn on once while online.
Yes. Recording carries on, and the lock screen shows the time with a Stop button. It never shows your words.
No. There is no account, no analytics and no Murmur server.
