Soapstone

Write messages anywhere on the planet. Read them also, if you're close enough.

Soapstone is reverse geotagging. Rather than tagging a post with a location, tag a location with a message! Others with the app can read your message but only if they're close enough to where it was written.

Soapstone uses a phrase builder that allows you to create a wide variety of phrases. Leave one at your best friends house ("simpleton ahead"), your local city library ("silence therefore stealth required ahead"), on top of a mountain ("I did it!"), or at your favorite coffee shop ("Hurrah for artisan!").

Your device will receive a notification if one of your messages has been rated up by another user.

Soapstone is entirely anonymous, no account is necessary.
