UoP Bus
Read full descriptionHide 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 โข Both lines on one map: the U1 loop and the U2 in each direction, with every stop. โข 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 โข Your closest stop comes first, with the walk there and a countdown to its next buses. โข It tells you when to set off: "Leave in 4 min to catch the 20:50 U1". โข 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. โข In the last two minutes, the countdown goes down to the second. NO NEED TO OPEN THE APP โข 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. โข Reminders arrive 15 or 30 minutes before the bus, as time-sensitive notifications. โข 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 โข A clear warning when you're looking at the last bus of the day. โข At weekends, in the holidays and overnight, it shows the service notice and when the first bus is back. โข If the buses stop reporting their position, you'll know. EVERY STOP AND TIMETABLE โข Each stop's timetable for the day, with a line at the current time and earlier buses tucked out of the way. โข Star the stops you use, and find any other by name, nearest first. โข Timetable changes arrive on their own, without waiting for an app update. MADE FOR IPHONE โข Dark Mode, the largest text sizes, and VoiceOver labels on the map and controls. โข 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

MobileFlare (Mobile Flare) is a free safety alert app for crowded events. If something goes wrong - a medical emergency, a personal threat, dangerous crowd pressure or dehydration - flash your phone screen in the appropriate colour to signal for help. No shouting required. No signal required. No searching for a steward in the dark. Just hold a button. Hold your phone up. Help comes to you. HOW IT WORKS ------------------------ Open MobileFlare (Mobile Flare). Four buttons. Press and hold the one that matches your situation. Your screen flashes at full brightness in the correct colour. Hold it above your head. Anyone who can see it knows exactly what you need. RED :: Personal Safety / Assault YELLOW :: Crowd Pressure GREEN :: Medical Emergency BLUE :: Water Please (calm static screen โ non-flashing) Signals flash at different speeds as well as different colours, so they can be identified by rhythm alone. This helps users with red/green colour blindness distinguish between signals clearly. Help friends find you in a crowd. Pick a colour from the new spotlight sub-menu and hold up your screen: a solid, non-flashing colour will help you stand out. Colours are distinctly different from the emergency colours. WHY IT'S DIFFERENT ------------------------ โ Works with no mobile signal, no Wi-Fi, no Bluetooth โ No registration, no account, no login, no tracking โ Zero data collected - we don't know you exist โ No adverts, no in-app purchases, free forever โ Instant to use - under a second to activate โ Maximum screen brightness during activation โ Forces portrait orientation - works in any grip โ Dark interface designed for venue environments FOR PARENTS ------------------------ Young people attend more live events than ever - often without adults who would know what to do in an emergency. At a sold-out standing concert, ambient noise can exceed 100 decibels. Shouting for help won't carry more than a few people in any direction. MobileFlare (Mobile Flare) gives the instinct to reach for a phone, somewhere useful to go. Show your child, friends and family the four colours before their next event. That thirty-second conversation could matter. ABOUT MOBILEFLARE (MOBILE FLARE) ------------------------ Built by one person, a father of daughters. Based on personal experiences of seeing emergencies unfold at live events, no-one knowing how to correctly attract attention, and witnessing how long it takes to locate someone who needs help in a crowd. MobileFlare is free. It will always be free. Learn more at https://mobileflare.app

Verdict
The clearest difference is update cadence: MobileFlare at every 3 weeks against UoP Bus's every 6 months. MobileFlare also leads on device support (3 vs 1) and iOS requirement (15.0 vs 17.0). On price, ads and in-app purchases there is nothing between them.
