Is there an app to take a photo and add a comment to it Does anyone know of an app, which allows to take a photo and add some comment or notes to it?

Doesn't have to be anything fancy. I'd just like to take a picture of something and add some comments/notes (e.g. while shopping, take a pic of something and make a note of its price).
Catch notes should accomplish this very well. They even have a widget that allows you to take a picture and go straight into their editor to comment and add notes. Highly recommended. They also have a web counterpart which may make viewing/managing your notes easier.
