Ratings and reviews

It's 2025, and your web interface still has no OPP? No classes? No instances? No runtime component duplication AT ALL? I still gave this 4 stars because it's still pretty useful for making all kinds of apps, but having to define a finite number of components up front makes game development a bit of a pain. It's doable, but not as efficient as it could be. And yes, I already know about extensions, but this seems like something that should be a standard feature.

I have been a software engineer for the past 20 years. I developed for many types of devices, including Android. MIT AI2 Companion is just amazing! It speed up the dev process so much! It is pretty stable if you know what you do. I don't often write reviews but after reading some 1 star reviews I had to write one! It seems to me that people howadays expect too much without any knowledge whatsoever. You have here an amazing dev tool and still you complain. Stop developing if you can't handle it.

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!
