Completely disregard the master branch, it's a mess of outdated code from the old app
Instead, check out the branch intrepid-chris for an actual working version of the app
It's also important to note that the version of the MIT app currently on the Play Store is not the same as this app. That app is PhoneGap (shudders) and this one is 100% native. I'll leave it to you to decide which one you like better.
Why has a 100% native, ready-to-go app just been sitting up on MIT's github for 2 years?
That's an excellent question, I suggest asking MIT's IST department for an answer because I can't think of any good ones
