A little help,
then on your way.

LTA may not be supplying a usable prediction, a service may be outside its operating hours, or there may be a connection problem. LTA maintenance can also affect estimates. Missing data alone does not prove maintenance. Retry after checking your connection; we don’t invent an arrival time when a prediction is unavailable.

The clock marks an operator schedule-based prediction rather than one based on the bus’s live location. The bus may arrive earlier or later. Even location-based estimates can change.

“Arriving” means LTA’s estimate is less than a minute away; it does not confirm the bus physically arrived. “Last known” means the information could not be refreshed or is stale. A prediction becomes stale after 30 seconds without fresh data.

Live Activities receive updates from our server through Apple Push Notification service, even when the app is closed. Apple controls delivery timing; network conditions, system budgets or disabled Live Activities can delay updates. Check the update time and open the app for the latest available predictions.

Tap Untrack in the app. Only one service can be tracked at a time, and a session lasts at most 60 minutes. It can also end after Arriving when fresh predictions advance to the following bus; that is a feed change, not proof the bus passed.

Foreground location helps find nearby Singapore stops. It is optional: you can search and browse Singapore arrivals worldwide without granting it. To look up nearby stops, the app sends map bounds centred on your position. It does not request background location or store a history of your locations.

Download “Bus Where?” from the App Store.

LTA predicts the bus is less than a minute away, or still lists an estimate that has just passed. Check the service number when the bus reaches your stop.

The five-digit number for a particular stop. Stops on opposite sides of a road usually have different codes.

One row of windows means single-decker. Two rows mean double-decker. The icon describes that particular arrival, so the next bus on the same service may be different.

On compatible iPhones, the area at the top of the screen where you can see your tracked bus while using another app.

The latest available prediction. It appears when an update fails or the arrival data is at least 30 seconds old.

The iPhone Lock Screen display that shows your tracked bus, its stop and the latest arrival estimate.

The Land Transport Authority’s data service. It supplies the Singapore bus arrival, stop, service and route data used by “Bus Where?”.

There is no usable arrival prediction for this bus. The service may still be running.

Green means seats are available, amber means standing room, and red means standing room is limited.

A clock beside an arrival means the time comes from the operator’s timetable. The bus may arrive early or late.

A time you choose for the app to start tracking a bus automatically. Schedule times use Singapore time.

Track follows one service at one stop for up to 60 minutes. Untrack ends that session early.
