Very practical application

This application can be a great asset in picking out colors.

I tried to use. Each time I try it wants another purchase. Can’t figure out what I purchased to begin with since nothing works without an additional purchase

Developer Response ,

Thanks for the feedback. The basic version of the application provides the ability to work with the RAL Classic or RAL Plastics palettes without any additional purchases. If you need RAL Design or NCS palettes you can purchase them additionally. We would be grateful if you review your opinion.

Not what I expected

Thought I could apply & test colors on photos of house I have, not just the image of the house they provide. Disappointed I spent money on something I mistook it for.

Developer Response ,

I'm sorry you didn’t like the app. But we did not indicate information anywhere that in the app you can change the colors in the photo. Please make your review more positive. Our app has other useful features. Thanks for the feedback!
