Using this on desktop or a laptop is wonderful. But using this on a mobile device of any kind is difficult, laggy, and not very user-friendly, all of which makes work on the mobile version in the way of progress. The only reason I got it on mobile is because my laptop is in the shop, and my projects for school are becoming more demanding, so this was the only way I could do anything. The app opens and closes the keyboard over and over, making typos much more of an issue than on a real computer.
