I’ve just subscribed. Right now they’re offering %65 off the subscription price for early adopters (in the UK, anyway). This works out at just over £23 in the UK - and that price is the permanent subscription price, as long as my subscription stays active. I think that’s just the right price.
I mainly use Linux for development and don’t like having to get the MacBook out just to throw together a design.
Gravit Designer works the way I’d like Linux apps to work, it looks good and for the most part, it works well.
The trouble with many Linux users (myself included, at times) is that they expect everything for free.
Don’t get me wrong, I’m a big fan of FOSS and I love Inkscape BUT I’ve found Inkscape makes designing websites a bit of a chore compared to GD. In terms of the time saved, I’d rather pay £24 a year for a piece of software that I can use across all my computers and that backs up my designs to the cloud.
With the exception of Chrome and Thunderbird, all of the decent software I use on Linux, I’ve had to pay for. By the way, I can highly recommend Pixeluvo as a (paid) rapid image editing tool.
As an aside, as I’ve seen it mentioned, I am a heavy user of Affinity Designer on both the Mac and Windows. I think it’s an awesome app and I’ve ditched Illustrator in favour of it. Now I’ve subscribed to GD Pro, I’ll be seeing how it compares for artistic production (rather than just website wireframes and social media graphics).
