Picscribe lets you capture a memory around a photo by letting you add notes right into your pictures themselves.
Save your thoughts even when you are offline or traveling with limited data connectivity.
Even if you use a photo service like Flickr, Dropbox or Google+ to keep track of your photos, by keeping the notes inside the photos, you are ensured that the data is not lost when you switch services
Comments are saved right inside the metadata of the pictures and can be viewed within the app or other Exif data viewers.
XPERIA USERS PLEASE NOTE
The application doesn't seem to save data on Xperia phones. While we can't fix this on the app level, we are looking into alternative strategies for saving comments on those devices.
