Pincrumb turns the world into a map of little discoveries. Drop a photo, a note, or a voice message on the exact spot — a crumb someone finds when they wander near.
iPhone · Sign in with Apple · Anonymous handlesSee something worth sharing — a hidden mural, a great bench, a strange sign, a perfect view? Pin a tip to the exact spot. As you move around, Pincrumb pings you when you come within a few steps of someone else's.
A title, a photo, or a hold-to-record voice note — pinned to where you're standing.
A gentle sound and buzz when you're near a tip worth checking out.
Leave a spoken note on a trail. Hands-free moments, no typing.
You get a fun handle like “Swift Fox,” never your real name.
No account setup, no passwords to remember — just sign in and start walking.
