What do you love about Concepts? Do you pay for a subscription (and how much is it - I must be blind or I just can't find it on the website)?

It has a slick interface and has a "rightsized" feature-set, not too many, not too few. Just enough to be productive without overwhelming you with options.

I've installed android application and it showed around $2-3 per month for subscription. But I'm pretty sure it should be different in another country or for web.

I use concepts on an ipad pro for drawing and i bought the subscription for a few dollars. I prefer it over other drawing apps for ipad because it's vector based.
