Where is your next class? When can you see your friends? Barra brings your university day into one simple place. YOUR DAY, RIGHT AWAY Add one class without creating an account. See what is next, when it starts, and the room and lecturer you saved. Your guest timetable stays on your phone. Add the rest when you are ready. BRING YOUR TIMETABLE After signing in, choose a screenshot of your university timetable. Review the recognised classes, correct the details, and save. You can also add and edit classes yourself. A partial timetable is shown as partial, so missing classes do not become an invented free day. FIND YOUR CAMPUS PEOPLE Find people at your university, open a profile and send a friend request. You choose whether people can find you and what you share with friends. SEE A BREAK YOU SHARE When both timetables are current and sharing is enabled, see time you have between classes together. Open a conversation or share that time through your phone’s share menu. Make plans in your own words. YOUR NEXT CLASS ON A WIDGET Add Barra to your Home Screen or Lock Screen. Check your next class without opening the app. A short guide shows you how to add the widget. YOUR CHOICE Manual guest timetables work without signup. Sign in for campus profiles, friends, messages and screenshot import. Optional usage analytics can be allowed or declined without changing these features, and the choice can be changed in Settings. Barra is an independent app and is not affiliated with any university. Campus features depend on the universities available in the app. Questions or feedback: support@joinbarra.com
