PostSecret, the highly popular continuous online exhibition of anonymous mail art created by Frank Warren, is now available for iPhone users.

Since 2004, PostSecret has featured the act of people mailing in their secrets on a homemade postcard to Warren’s home in Germantown, MD, where Warren then posts them on his website for all to see… Anonymously of course!

The secrets range from funny, to horrifying, heartwarming, and are always moving.

The PostSecret App allows owners of said app to take photos of their secrets with their phone, add a 140-character message, and upload it to the PostSecret mobile community. Others will then be able to read the messages, leave comments, flag inappropriate content, as well as share their own secrets.

The app also features photo filters and the ability to share posts on social media sites such as Facebook and Twitter, and even through email.

The PostSecret App is for sale in the iTunes App Store for $1.99. A version of the app will be available for Android soon.
