If Grid Paint had an app, it would look something like this, plus it would be a lot more convenient because signing in the normal way is sorta tedious, but doing it on the go and on a phone would be a great way to waste time, plus it should have an offline mode to where you can save art that is a work in progress as a draft to finish it for later. Anyone else think that this is a good idea, COMMENT BELOW AND WE'LL PETITION FOR IT.
