CanDash

The OBD-II diagnostics app for car enthusiasts. Seven handcrafted gauge clusters. Live engine data. Powertrain Diagnostics. One price. No subscriptions!

CanDash turns your iPhone into the dashboard your car deserves.

Seven handcrafted gauge clusters — from analogue 1950s elegance to modern race-day digital — display live data from your car's OBD-II port. Choose your style. Customise every gauge. Build the dash you've always wanted.

Then take a peek under the bonnet. CanDash reads fault codes, monitors your check engine light, tracks performance, and helps you understand what your car is telling you. All offline. All private.

— DIAGNOSTICS —

CanDash reads fault codes from your vehicle's engine and transmission ECUs. Other vehicle systems (ABS, airbag, body control, infotainment, climate, etc.) are not currently supported.

• Read and clear current fault codes (Mode 03) • Read pending and permanent fault codes (Modes 07 and 0A) • Plain-English descriptions for 800+ standard SAE codes • MIL status and emissions readiness — useful before an MOT or smog test • Live engine and transmission data

— PERFORMANCE —

• 0-60 and quarter-mile timing • Live G-Meter with cornering and braking traces • GPS or OBD-based speed measurement • Trip data logging with CSV export

— PRACTICAL —

• Service light reset guides for 80+ vehicles • Service interval tracker • Real-time fuel economy with trip averaging • Fuel cost calculator • Custom PID support for advanced users

— SUPPORTED ADAPTERS —

CanDash works with any OBD-II adapter that supports the ELM327 protocol:

• OBDLink MX+ (Bluetooth Classic, MFi-certified) — recommended • OBDLink CX (Bluetooth Low Energy) • Veepeak OBDCheck BLE • Other ELM327 BLE adapters

— VEHICLE-SPECIFIC PACKS —

CanDash bundles manufacturer-specific PID libraries that add extra gauges and live readings to your clusters, dashboard, and Data Logging. Available libraries currently include:

• Jaguar Land Rover (AJ133 / AJ126 / AJD engine families) • Ford • Ford Focus RS Mk3 (Twinster torque-vectoring) • Volkswagen Group MQB platform • Mazda MX-5 NC • Porsche (petrol, diesel, and EV) • BMW • Toyota (petrol and hybrid) • GM Ecotec engines

These libraries provide extra live signals — they are not a guarantee that every PID will work on every car of the marque. Some PIDs are engine-, model-, or year-specific. More libraries in development.
