I Was Here — Make a Permanent Mark on the World! app for iPhone and iPad

Have you ever wanted to leave a mark in a place you have visited?
Now you can.

“I Was Here” is an app that allows users to post messages and pictures permanently at their current location. The post will be there for everyone to see, unable to be changed by anyone, but only people nearby can see the post. Perfect for a memento at a vacation or a new place you have visited!

You must allow the app to access your current location, or the app will not work.
You must also make an account. However, the posts you make are totally anonymous unless you identify yourself in the post.
