Write to [email protected] and tell us what you were looking at when it went wrong. The bus stop code and the service number are usually enough for us to reproduce it.
Arrival times won't load
The app needs a connection to fetch times, and it will show the last times it received with a note saying so rather than pretending they are current. If it keeps failing on a good connection, LTA DataMall may be having an outage, which affects every Singapore bus app at once.
A live countdown stopped moving
Live updates arrive by push notification. If notifications are off for Whenbus, the countdown on your Lock Screen will freeze at whatever it last knew. Check Settings, then Whenbus, then Notifications on your iPhone. Inside the app, the Live screen shows every countdown you have running and offers Restart on the ones that have ended.
Live Activities also end on their own once a bus has gone, and iOS may end one earlier than expected. That is normal, not a fault.
I swiped the Lock Screen banner away
Swiping the banner away does not turn live updates off. Open Whenbus and go to the Live screen: the countdown is still there, and that is the only place it can be found once the banner is gone.
Nearby stops are wrong or missing
The list follows the map, so it shows what is in view rather than what is closest to you in absolute terms. If it looks wrong, tap the locate control to recentre on yourself. If location is off, the app cannot sort by distance and says so.
Something else
Email [email protected]. If it is a feature request rather than a fault, say so and it goes on a different list, which is a real list.
