Absolutely incredible
This is an amazing app. The brush strokes are fluent and smooth and make you feel like you are really using a brush and ink. The ink also acts realistically e.g.the faster you swipe the less dark it is. There are endless possibilities with this app! I also love the different paper templates you can use; they add a lot of depth and feeling to your drawing. My only suggestion is that you should be able to undo more than once and save your creations because you can make some pretty amazing things!
