The following review on App store UK is the kind of stuff that keeps us moving forward.
Auryn, is an absolute gem of an app and deserves so much more exposure than it seems to get. There is no other app with as realistic a brush engine for watercolour simulation. It does not try to fake the ‘look’ of watercolour, it uses physical simulations, and as such can be a challenge for the uninitiated.
Don’t let that scare you off though, with its straight-forward and simple controls you have a lot of power at your disposal. Once you get the hang of it you can use Auryn like you would real watercolours, i.e. highlights are the colour of the paper and are added using the idea of negative space. Just like real watercolours, this takes careful planning, but is extremely rewarding once it the approach clicks.
I would suggest starting out with the saturation slider almost to zero, and build up your colours without letting them dry in between. With the canvas tilt preference ticked this will also pool the pigment of the paint to give you a genuinely realistic watercolour behaviour —dark edges distinctive to real watercolour start to appear once you break to let the paper absorb your last few strokes and dry.
This last part is the difference between an app that merely does a decent job of mimicking the end look of watercolour— alá Pixelmater— and a brush engine that is a true to life physical water simulation. Adobe sketch tried this with a recent update but it doesn’t even come close to Auryn’s realism!
There are a few rough edges here and there. The iPhone version of the interface is a scaled version of the iPad which makes it very cramped. Incidentally, this is sort of like the opposite of a phone app being overstretched on an iPad interface. The gallery and lack of a document structure feels a bit unintuitive and not fully thought out. This is mostly sidestepped by using the iOS camera roll instead of the app gallery and is infact, exactly what I do. I don’t tend to bring line work in from other apps as I don’t like the way it mixes with the watercolours on the wet layers.
However, the simplicity of this programme wins out in the end. Don’t get the wrong idea that this is designed as a general purpose image editor —it most definitely is not. This is made from the ground up to do water colours as close to the real world as possible. There is of course the added benefit of no mess after and undo. Apple Pencil support is very good. Both tilt and pressure are well implemented. Watch out for changing the tilt mid-stroke, remember it is simulating a brush rather than a ‘pencil’. **TL;DR** download and start enjoying the best watercolour simulation available. I have no hesitation giving Auryn 5 stars. I use this app daily and get a lot of joy out of doing so.
Thank you so much
