OBD Ninja: Visualize Your Drive

OBD Ninja is the ultimate drive companion app that turns your car's hidden OBD2 data into beautiful, real-time visuals. Just connect an ELM327 Bluetooth LE OBD2 adapter and instantly monitor speed, RPM, fuel economy (MPG), and G-force on a live dashboard.

From daily commutes and weekend road trips to track days, OBD Ninja records your drive with GPS logs, dash cam footage, and telemetry overlays — so you can replay every drive and review your driving with precision data.

【Key Features】

■ Dash Cam with Telemetry Overlay
Record your drive with live OBD2 data — speed, RPM, G-force — overlaid directly onto the video. Supports up to 8x playback speed for quick reviews.

■ Fuel Economy Monitor & Coin Alert
Track real-time MPG along with the volume and cost of fuel consumed. Our unique "Coin Alert" plays a satisfying coin sound every time you spend a set amount (e.g., every 10 cents).

■ Drive Log (GPS + OBD2 Tracking)
Synchronize GPS and OBD2 vehicle data to keep a detailed record of your trips. Replay routes on a map and analyze your driving later.

■ Real-Time OBD2 Dashboard
Display live vehicle data directly from your OBD2 port. Choose from various themes and layouts to suit your style.

■ GT View
A specialized HUD display mode inspired by racing games. Multiple gauge layouts are available for a professional cockpit feel.

■ JDM Speed Chime
A faithful recreation of the nostalgic 100 km/h warning chime found in classic Japanese cars (AE86-style) — a tribute to JDM culture that adds a touch of nostalgia to every drive.
With the new "GPS Chime Mode", no OBD2 adapter is required. The chime works on GPS speed alone, with a dedicated screen featuring a map and a large speed readout.

■ Flexible Customization
Fine-tune your experience by adjusting display ranges, units, and more.

■ PC Integration
Seamlessly transfer data to your PC via QR code. Use the desktop companion app to export videos, create timelapses, and manage your drive library.
