Dead Letter Drop

Pin anonymous voice messages to real GPS coordinates. You have to be there to hear them.

Work Narrative

Q

How did you come up with this project?

A

It started as an installation art project in Berlin. I hid 10 USB drives in public walls; people loved the feeling of a treasure hunt, but hated plugging unknown USB drives into their laptops.

Q

How often do you use this product yourself?

A

Anonymity is absolute—there are no accounts and no metadata, other than the GPS coordinates and the audio itself.

Manifesto

How it works

Open the app, record a short voice message (up to 90 seconds), and pin it to your current location. That's it. No feeds, no profiles, no likes. If someone opens the app within 50 meters of your drop point, they can hear it. Messages are automatically destroyed after 7 days.

Every city is full of conversations that never happened—simply because those people were in the same place at different times.

Design Principles

Anonymity is absolute. We do not keep any recordings on our servers beyond the 7-day window.
