Cool tool. Built my first custom app in less than 24 hrs from the time I found this tool to publishing my apk. I have never built an app before and between the puzzle pieces and hundreds of tutorials at the site and on youtube I had version 1 (the input data and calculation and output data) running in <24 hrs. Adding more advanced features like email and file attachment took a little longer. I've heard there's an iOS version too. can't wait to try that too and get my iOS users up and running!

This app made me want to shoot myself and all of humanity. If you value your sanity, I suggest learning scratch instead. All that this app is (which was made by MIT by the way (one of the best universities in the world lol)), is complete and utter garbage, and is basically scratch but hideous. It also gave me pneumonoultramicroscopicsilicovolcanoconiosis. Cons: One-indexed Functions are called procedures Things are labelled horribly (^) 3 fonts UI made me want to jump off of a bridge Pros:

I thought that MIT is a great technology university but from this app, it doesn't look like it. Firstly, the website looks like it was made by a web developer who doesn't even know what they're doing. The page always becomes unresponsive and there are bugs every second. Second of all, the AI2 Companion is even more worse. Whenever I connect my device using the app, the images never loaded! Whoever owns this trashy app, please update it or else I will find a way to give it a zero-star rating. >:(
