5/5Must have app
I’m an artist. Have been all my life. Recently I have started painting. I paint things that fuel my passion. If you paint Notanizer is a must have app. You can take any photo and let Notanizer do its thing and your imagination is endless. Give it a try.

5/5Great Artist Utility App
Love that it just works and there are no micro transactions. Easy to use interface. whats the deal with that sound effect? seems like there could be a better way to indicate that level limit has been reached.

4/5Update issues
I like this app a lot, I use it all the time to adjust the values in my paintings. Since the last update however I have lost the ability to export images. When I try to export the app crashes on my iPad. On my iPhone when I try to export the export to photos option just doesn’t come up. Please fix. My work around for now is to take a screen shot to save the adjusted image and just crop to the image itself.

5/5Notanizer
I wrote a negative review and was contacted by someone who “fixed” the issue I had. I’m now giving a five star rating because of the exemplary customer service and the persistence displayed in solving the problem.
