About

UoP Bus

Features
Read full description

UoP Bus tracks Portsmouth's U1 and U2 university buses live, works out when you need to leave for your stop, and keeps a countdown on your Lock Screen. Get to the stop as the bus does, not ten minutes before it. Whether you ride the U1 loop through Southsea and Eastney or the U2 out to Langstone Campus, every stop on both lines is covered. SEE WHERE YOUR BUS IS • Both lines on one map: the U1 loop and the U2 in each direction, with every stop. • Live buses, each with an arrow showing which way it's heading. Tap one to see how recent its position is. KNOW WHEN TO LEAVE • Your closest stop comes first, with the walk there and a countdown to its next buses. • It tells you when to set off: "Leave in 4 min to catch the 20:50 U1". • When your bus is under ten minutes away, the countdown follows the bus itself rather than just the timetable. The timetabled time stays alongside, so you can always compare. • In the last two minutes, the countdown goes down to the second. NO NEED TO OPEN THE APP • Set a reminder on any bus and a Live Activity follows it on your Lock Screen and in the Dynamic Island: the countdown, when it's due, and the bus making its way to your stop. • Reminders arrive 15 or 30 minutes before the bus, as time-sensitive notifications. • Widgets for your Home Screen and Lock Screen show the next buses from your closest stop, wherever you are, or from a stop you choose. NEVER GET CAUGHT OUT • A clear warning when you're looking at the last bus of the day. • At weekends, in the holidays and overnight, it shows the service notice and when the first bus is back. • If the buses stop reporting their position, you'll know. EVERY STOP AND TIMETABLE • Each stop's timetable for the day, with a line at the current time and earlier buses tucked out of the way. • Star the stops you use, and find any other by name, nearest first. • Timetable changes arrive on their own, without waiting for an app update. MADE FOR IPHONE • Dark Mode, the largest text sizes, and VoiceOver labels on the map and controls. • Unfold an iPhone Duo and your stops sit beside the map. Star your stop, add the widget, and leave at the right time. EULA: http://www.apple.com/legal/itunes/appstore/dev/stdeula
