Leave a line on the map and let it slowly fade away

Last updated 1 November 2026 (Murmur 1.1)

Murmur lets you start a thread right where you are, and anyone nearby can read it and reply. Threads have a lifetime: when time is up, they melt away. Murmur also draws where you went each day as a snake that stays on your iPhone.

Threads on the map

• Write what’s happening here, add up to 3 tags, and choose whether it melts in 1 hour, 24 hours or 7 days.
• People nearby see your thread on the map and can reply, like it and follow new replies. Every new reply keeps a thread alive a little longer.
• In each thread, everyone is a little picture and a name, like “🦦 Sea Otter”, and a different one in every thread. There are no profiles, and no way to look up who posted what.
• Save the area, time and tags you want to see as lenses.

Your location is blurred

A thread’s location is blurred to about 150 m and shows up only after 0–3 minutes; your precise location is never stored. 24 hours after a thread melts, it is permanently deleted from the server. See the Privacy Policy.

Keeping it kind

Murmur is only for people aged 18 or over, with one account per person. Posts are checked automatically before they go up, reports are handled within 24 hours, and you can block anyone. We have zero tolerance for objectionable content and abusive users: read the Community Guidelines and the Terms of Use.

Your daily trail

• Murmur records the paths you take and draws each day square by square on a blank page, like the classic snake game. Every segment shows how you were moving, and every place you stopped is a piece of fruit.
• Walking, running, cycling, driving and the metro each have their own emoji, and you can swap any of them; or draw a classic single-colour snake.
• Drag the timeline to see where you were and when; switch to map view to lay the same route over Apple Maps; on the calendar, every day you recorded is a little snake.
• Your trail stays on your iPhone and is never sent to us. You decide how long to keep it, and you can delete all of it at any time.
