Built on Singapore's open transit data — Land Transport Authority (LTA) DataMall for live arrivals and routes, OneMap for map tiles and address search, Singapore Land Authority (SLA) datasets for geospatial routing.
Live countdown for every bus stop in Singapore, refreshed automatically every 10 seconds. Each row shows the bus type — single-decker, double-decker or bend bus — load, and whether it's the last service of the day.
All six MRT lines plus LRT — line maps, station codes, first & last train times by day type. Tap any nearby station to jump directly to the line view.
Search across bus services, bus stops, MRT/LRT stations, addresses and OneMap places. Recent results stay on-device so you can pull them up again offline.
Multi-modal routes that combine bus, MRT/LRT and walking legs. Pin an itinerary to keep it on the home screen for up to 24 hours.
Set a reminder on any service and BellBus rings before it arrives — based on live ETA from LTA DataMall, not just a fixed timer. All notifications run locally; nothing is pushed from a server.
Stops within 800 m and stations within 500 m, ranked by walking distance. The list re-fetches automatically when you've moved more than 50 m.
With your permission, BellBus uses precise location to find stops within 800 m and MRT stations within 500 m. The closest stop is auto-expanded with live arrivals.
Tap any address or place to plan a route. BellBus combines bus, MRT and walking legs powered by OneMap and SLA datasets.
Tap the bell on any service. BellBus watches live arrivals and rings before the bus reaches your stop — entirely on-device.
Last-bus indicators, MRT first/last train times by day type, and clear "no service" labels mean you'll never be caught out at midnight.
All MRT and LRT lines, with full station listings, line maps, and first/last train times by day type. Bus services covered: every regulated route in Singapore via LTA DataMall.
BellBus is designed to comply with Singapore's Personal Data Protection Act 2012 (PDPA), Apple App Store Review Guidelines and Google Play Developer Programme Policies.
No email, no phone number, no social login. The device authenticates the API with an Ed25519 key generated and stored on-device.
Coordinates are sent only when querying nearby stops or planning a trip — never logged to a profile, never sold, never shared with advertisers.
Bell reminders use local notifications. There is no remote push channel, so we don't keep any device tokens.
Settings → Clear cache or Clear local records lets you wipe favorites, history, pinned itineraries and reminders. Switching to limited mode revokes the device key entirely.
