I like it very much, but it is very expensive.
I would like to pay for a subscription and support the developer, but the amount they ask for a yearly subscription is too high. Paying $50 for a yearly subscription is too much for my country. My salary is only $300 per month. If we assume that the subscription would cost only $10 per year (as notability cost), I am sure that many more people could afford it. Or it would be great if premium access could be purchased one-time, even for the same $50.
