Anyway by default you get a standard fountain pen, with settings for wetness and size.. which means you can drawlike Ralph Steadman.
Or you could if the algorithm that turns your line into a line on the screen was a little bit more predictable... several times I managed to lose a line, or select an area instead of drawing a line.
The toolbar is simple, and can be hidden or pinned to the page, there are additional pens at additional cost, and various different paper types, that are more of interest to note takers. Pinch to zoom works without issue as long as you are in the right mode, and there's even a funny little zoom box thing- no idea why you'd use it.
There are a couple of odd settings, like the switch to pen after using the eraser, and this caught me out a couple of times. There's no fill.
There are however proper undo and redo buttons.
Export is to photo gallery as a .png, mail or to a printer.
...and that's about it.
I like it when it does what I want it to, but its all too easy to select and area rather than drawing what I want, and I don't want to change my behaviour to fit an app.
Draw a penguin was the challenge, and I think the line is nice and expressive on the eye.
