Close all apps and restart your iPad. Let me know if it helped.

Yea,we will rather not publish new features before switch to new engine.

I’d be happy to learn what we should take from Notestudio from the testers

What will be the benefits/differences for Artstudio Pro once it's ported to the new graphics engine?

1. We wrote ArtKit engine from scratch, in pure Swift, while Artstudio Pro is written in obj-c. Here is the list of advantages:
- it is in pure Swift and supports both OpenGL and Metal, so it will be possible to make Artstudio for Windows / Android, but don't expect that soon
- faster - because Swift is faster than objc)
- faster and more memory efficient - we had a lot of experience from Artstudio so we made many thing in a different, more efficient way
- we separated stroke processing from other things so we have better control on stroke stabilization / smoothing / dynamics etc, we may add more options in brush editor
- we implemented texture compressing so the memory usage will be lower and it will improve performance in large documents (a lot of layer, big dimension) because it will first compress layer data on low memory, then save it to disk if there is still no free memory
- besides we learnt a lot of things when working on a new engine and on Notestudio which is vector based app

2. We switched to SwiftUI in Notestudio and wrote separate framework for the UI - ArtUI. It will improve UI a lot
- we made draggable panel mechanism (used in Notestudio), we are going to use it in Artstudio too
- SwiftUI has better support of localizations, light/dark mode, controls refreshing, small animation here and there etc

Things in iOS are changing very fast. To make Artstudio alive we had to make really big steps every few year. First Artstudio was released in 2010, then rewritten almost from scratch in about 2015, then rewritten almost from scratch again in 2019 and released as Artstudio Pro, it seems it's time for the next big step...

Of course we will not stop it.

We developed totally new panel-based UI in new Notestudio app that will be released in December.
We are going to use it in future Artstudio update.

thank you for the update & hearing from the developers! I too love the app (paid the full version) and would be unfortunate if developers deserted it. I think it also has many many potentials like ui improvements. Hopefully when you guys get back to development you add more stuffs to art studio pro


also some suggestions for asp: add a sidebar option ( tools in the top are really unintuitive than before which were in the sides. On transform tool it would be cool if the apple pencil pro can rotate the “selected transformed area” by barrel roll. Also I think the quick menu could have an option for the texts to be replaced by icons for aesthetics (maybe custom icons too). Maybe add more gestures to asp like two finger swipe up for maybe like last tool used.

Overall please dont stop developing artstudio pro, maybe take breaks but dont give up on it . Though on a serious note please invet in sponsors as the app is severely underrated and overthrown by the everpopular procreate (I actually tried it & had it refund for lack of features compare to this awesome thing  )

Unfortunately however our team is not too big and we just don't have too much time for non-app activities.

We will consider that in the future

New version with improved barrel roll is available on the App Store!

It is not possible, sorry.
We cannot implement that because in Artstudio we have a lot of brush parameters that are not supported by Photoshop, so they cannot be saved in abr.
