In this first phase, the App aims at students in particular, providing an alternative access to services and content that are already available on the web: users will be able to consult their student record, see their professors' contact information, view their class timetable, read University news and search for free study rooms. Here is an overview of its main features: - STUDENT RECORD: navigate through the list of courses, find information on your program of study, view your grades - CLASS TIMETABLE: consult course calendars and create your personal timetable - ROOM AVAILABILITY: find out which rooms are free, in which department, and for how long - NEWS/EVENTS: stay up to date with news and events organized by the University or a Department - DIRECTORY: find the contact details of your professors and add them to your favourites to read their notices and office hours and learn about their thesis proposals You can login to the app using your UniTrento credentials. Student record data are automatically synced with ESSE3 data.

Verdict

The call

The clearest difference is in-app purchases: UniTrentoApp at none against Opal's 18. UniTrentoApp also leads on device support (3 vs 1) and iOS requirement (15.5 vs 18.0). Opal's advantage is update cadence (every 5 days vs every 2 months) and chart position (#45 vs unranked). On price, review sentiment and ads there is nothing between them.
