Gantry SG
ERP, balance & alerts in view
Only for iPhone
Free
iPhone
Gantry keeps the things you actually need while driving — your ERP road-pricing
charges, cashcard balance, speed, and road alerts — on a clear, always-on display
in your car. Your phone does the work in your pocket; the display is what you watch.
Gantry connects to your vehicle's OBU (On-Board Unit) using LTA's official OBU
API/SDK, parses the ERP 2.0 messages, and relays just what matters to a dedicated
in-car screen over Bluetooth. No more glancing at your phone to check a charge or a
low balance.
WHAT GANTRY SHOWS
• ERP charges and cashcard deductions, the moment they happen
• Your card balance — with a heads-up before it runs low
• Current speed and speed-limit signs
• Speed cameras, parking availability, travel times, and official LTA road-sign alerts
• A big, legible clock and speed when nothing else needs your attention
BUILT TO STAY OUT OF YOUR WAY
• A priority-driven layout decides what matters most at each moment
• A built-in preview mirrors the display, so you can set it up and confirm it works before you drive
• An Activity feed logs every charge, deduction, and alert so nothing goes unnoticed
• Live Activities and widgets keep your balance on the Lock Screen and trip status in the Dynamic Island
• Pair by scanning a QR code — then it reconnects automatically every time you get in
• Customise brightness, theme, which alerts to show, message timing, speed, and clock
OVER-THE-AIR UPDATES
New display firmware is delivered straight from your phone over Bluetooth — verified
before installing, with automatic rollback for safety. No wires, no computer.
REQUIRES THE GANTRY DISPLAY
Gantry is the companion app for the Gantry Display, a round AMOLED screen for your
car powered by a single USB-C cable. The app's job is to bridge your OBU and the
display — it is not a standalone dashboard, and the hardware display is required to
use it. Learn more and order at gantrydisplay.com.
Built for Singapore's next-generation ERP.
