If you're an existing user and you're experiencing update issues (store error c101a7d1 / 80004005) or if you have lost your purchase license after reinstallation, please note that this issue is caused by a recent glitch in the Windows Phone Store licensing system and NOT the app. Please contact Microsoft Windows Phone Support (via online chat) to assist you in reinstalling the app and have your license reinstated. Thank you.
Phototag adds information overlay on photos taken with the in-app camera or photos from the media library. It's handy for documenting captured moments on the photo itself and sharing the photo with others.
