    Idea is excellent, but my experience was ruined by occasional weird viewport offset bugs where I suddenly couldn't see half the screen because it had moved outside my phone screen.

    This is probably a good app, but I dont know because it doesn't work. It crashes whenever I try to go on a tutorial. Fix it now.

    Fantastic app unlike anything available on any other system, just needs the sound effects disabling by default!

    Does not run on my Lumia 1020 running Cyan update (WP8.1). Shows the "Just a moment" screen and progress bar moves (very nearly) all the way from left to right, but then it just sits there, like it's frozen. There's about half a millimeter of progress bar still to go. Is it doing something? I don't know. I've left it quite a few minutes. Should I wait longer? If so, how much longer? Is it something odd about my phone? No messages so nothing much to go on. It is working for others, so how to I find out why it's not working for me? If I ever get it to work, I'll post a new review.

    Very good app, for me (a student) it makes a great way to introduce myself to app development, and is a great way to start developing apps. I will say, however that it is not perfect, sometimes the app will render itself off screen or when you tap one list item it can bring up another, and when exporting pictures don't work, other than that however, brilliant, I would definitely recommend touchdevelop to a friend

    Absolutely love this app. The only problem is that on my Lumia 630 it goes off the screen abit on the left, making some of the content cut off

    This really needs someone to check it on windows phone 8.1. For example: try to run the quadratic equation tutorial and notice that it's impossible for the user to enter a negative number as requested. The 'Number' type only presents a phone number keyboard with no '-' key. Shame because this could be a fantastic app builder.
