I downloaded to my mac and images would just come out white.

artists you know how important it is to get values right. this app lets you create a symphony of values and get good values-think.

Love this app. It helps me with all of my artwork as I play with the possibilities! Thanks!!!!!

really simple ui and did exactly as advertised. id say it’s a good investment, but you can definitely find free apps with b&w sliders if ur just looking for that

Really helps me see shapes and contours! Use in drawing studio a lot.

I really wish there were a way to save a NAMED file to my mac. The only current option I see is to save it to the Apple Photos app with a predefined name. Saving your image in the folder of your choice seems like an essential feature that should be there. I should not have to do multiple steps to get one image to my chosen location.

I’m a painter and I use this app all the time. Super useful

Simple and eye-opening. The only thing I wish to change would be to disable that terrible sound when you try to set levels too high or low.

I'm an art insturtor of adults in Colorado and have found this app to be indespencable in teaching values. It's simple to use and effortlessly comunicates visiually the most powerful tool in art, values. I use this tool almost daily. Bravo, to you, good people at Notanizer!

This is a great tool for Plein Air painting
