This app is made to help out the freshers of IIT Guwahati. They can login within the app to access the entire schedule from lecture timings to lab timings and receive announcements within the app via instant notifications using GCM. The app is still under development but can be accessed using the following credentials. I was responsible for both the back-end and front-end of the app.
Username - a.dalmia
Password - amandalmia

The libraries used in the app are:
