This app is great! All the art materials in it is crazy! I love how you can get different pencils, and different pens. The choices are not limited, and I have to say I’ve made a ton of good art and calligraphy with the app. It is very compatible with the Apple Pencil. I’m addicted to this app! Two things though. Number one, layers. If you are a digital artist, you need to be able to hide layers, show layers, etc. they help you a lot. I saw no layer button, so I had to erase around my line work! Sure, it’s good for doodling, but if you want a good piece of art work, we should be able to access layers. Number two, the colors. I was trying to change the color of the calligraphy pen, but I found out I wasn’t able to. This is a very crucial thing if you are an artist. There are a ton of color crayons, but what about the pens? The calligraphy pens? Other than that, great app. It doesn’t flood you with ads, and you can make amazing art.
