AirBagWeight - Truck Scale

AirBagWeight turns your smartphone into a portable truck scale.

Using Bluetooth pressure sensors installed on your air suspension system, AirBagWeight calculates real-time per-axle weights with accuracy within 1–2% when properly calibrated.

How It Works
Install a sensor on the air suspension hose near an air bag — one sensor per leveling valve. Connect via Bluetooth, calibrate once at a certified scale, and weigh your axles anytime — right from your phone.

Why AirBagWeight?
One overweight fine can cost $1,000 or more. AirBagWeight pays for itself the first time it keeps you legal. Know your weights before the DOT does.

Features
• Live axle weights — steer, drive, and trailer — on one screen
• Overweight warnings against your axle limits
• Weight history with notes and PDF export (Pro)

Works with any truck or trailer with air suspension — semi trucks, day cabs, straight trucks, and trailers.
