Pretty good app, just one suggestion

This app is pretty good, and the various correction filters are relatively accurate, but there's one thing that I would like to suggest— please fix this annoying glitch that disables the app's access to my photo album app, I'm not a fan of needing to restore my purchases every three days. Other than that, a pretty good app.

Demo Mode. Pay $ for colors.. wth.

Only ten colors unless you buy the full palette. Wasn’t accurate enough for me to buy it. Kept calling obvious colors grey
