This app doesn't upload to their servers —therefore it doesn't work at all. It's a non-functioning piece of nothing. It should be removed from the store.

Upload a black and white photo says cannot convert select another photo.

I opened a B & W photo but do not see a "Colorize" button anywhere??? Is this app still being supported?

This is not event an app, just an interface that interacts with their servers. Photo colorization is slow and once you get your photo, if you try to make any changes the image becomes pixellated and blurry.

loaded an image and couldn’t adjust anything

it really works!
