Initial impression

Fantastic for planning diy projects.
Being about to see measurements as you manipulate objects is so useful.
App is intuitive and fast.
After 1 day of use, it’s my goto vector app.
I’ll probably never open affinity designer ever again ;-)
(‘I love procreate, but I generally need vectors).
Congrats to the Concepts team.
Btw - I stumbled on your app after a Gemini chat. Google search didn’t surface your app. You’re not easy to find?
Glad I found you.

Integrity - worth supporting

Concepts deserves credit for doing something that has become surprisingly rare: honoring the people who supported the app early. I bought the app years ago, and my purchase still means something today. I wasn’t pushed into a subscription just to keep using features I already paid for.

That kind of integrity matters. It builds trust, and it makes me much more willing to keep using and recommending the app. Thank you for respecting your longtime customers instead of treating them like a captive revenue stream.

The best tool around

Invaluable tool for designers

Doesn’t remember your purchases

I have been a user of this application since the very beginning. I have always been a pro user and have paid to unlock all of the features of this software. This application currently has a bug where it will forget which features you have paid to unlock. And it requires you to sign into the Apple Store to restore your purchases. The problem is that this happens to me multiple times per day. And I frequently work in the field off-line where there is no internet connection. So I am unable to open and work in certain files, especially when I have used pro features. This is very frustrating. No amount of restarting the application or restarting my iPad will fix it. It’s at the point where the app is unusable. I have tried opening Support tickets, but nobody seems to want to fix the problem.

If you download this app, don’t bother paying for the pro features because you may not be able to use them all the time.
