I’m in love with this app

I only recently discovered the world of creative coding and generative art, I hope theres plenty in store for the future of this app. There are a couple things I’d recommend adding, for example I can’t find any clear way of renaming a file and I have seen some JavaScript libraries that allow conversion from Processing to JavaScript to easily make your creations web-compatible, that would be a great feature to look forward to. Thank you for this great app, I can’t recommend it enough.

Great, but needs work

This is a great app and it helps a lot with testing out little sketches and things like that, but it does not work for running larger things, no matter how simple. The main reason for this is the lack of error messages, which would make the app a whole lot more usable. The app could also do with some formatting help, like auto-indentation after curly brackets for example, as well as supporting PVectors, which make programming with objects much easier.

Overall a great app, but one that could do with some work.

I would rate this five stars because it makes experimenting with quick stuff much easier, even runs when offline which makes it perfect.
