One must say that this app is still in development First, it looks like, since it is the first version only and is published only recently. The biggest problem is probably that you can not edit photos taken with the app already, but only that which you have caught her. It is also a major problem that the app must save for ages after each snapshot, which can be quite annoying. Also it depends on me every time I want to go into the gallery of the app. But in itself it is a very good idea and the filter are top quality, what indeed is the real reason of purchasing this app and as I said, the app is still in development phase.
Update: You can already edit shot photos, but not from the system gallery, but only from the gallery of the app. I would like to see if that would also go. Therefore +1 Star
Please fix all the bugs yet, then it would be a perfect app
