DashBoost - Real-Time OBD2 Car Dashboard, Diagnostics & Performance Meter
Turn your iPhone into a professional-grade digital gauge cluster. DashBoost connects to any ELM327 OBD-II adapter to stream live engine data straight from your car, including speed, RPM, boost, temperatures, fuel, horsepower, and more, with beautiful gauges, deep diagnostics, and drag-strip performance testing, all in one app.
Built for enthusiasts who want to tune smarter, DIY mechanics who want to fix it themselves, and daily drivers who just want to know what their car is really doing.
Live gauge clusters that look incredible
Choose from ready-to-drive dashboards and watch your car come to life in real time:
• Classic Dashboard with timeless analog speedometer and tachometer
• Modern Dashboard with sleek, high-contrast digital gauges
• Performance Dashboard tuned for the track and spirited driving
• Tuner Gauges for boost, MAF, intake temperature, timing advance, and estimated horsepower and torque
Every gauge is rendered with smooth, responsive animation and a gorgeous Liquid Glass interface.
Build your own custom dashboard
Design the exact cluster you want with the built-in dashboard builder. Pick your layout, choose your gauge order, and drop in the readings that matter to you, then style each one your way:
• Accelerator position, boost, coolant temperature, fuel level, intake temperature, MAF flow, oil temperature, speedometer, tachometer, and timing advance
• Gauge styles including Text Only, Classic, and Modern
Save unlimited custom dashboards and switch between them with a tap.
Measure real performance
Find out exactly how fast your car is. Run true 0-60 mph and quarter-mile tests measured live from your engine, then save every run and compare your times over days, mods, and conditions. Your best passes are always one tap away.
Read and clear check-engine codes
Skip the trip to the shop. DashBoost scans your vehicle for diagnostic trouble codes (DTCs), explains what each one means with a built-in trouble-code database, and lets you clear codes and reset the check-engine light right from your phone.
Pass your smog test with confidence
The Emissions Check reads your car's onboard readiness monitors and gives you a clear ready or not-ready summary before you ever get in line, so you know you'll pass before you go.
Datalog everything
Record every sensor while you drive. DashBoost streams each reading to a CSV file on your device as you log, so an in-progress session survives even if the app closes. Export and share your logs for tuning, troubleshooting, or deeper analysis.
Estimate horsepower and torque
See real-time estimated horsepower calculated from your mass air flow sensor, with torque derived from HP and RPM, perfect for tracking gains after every mod.
Navigate while you monitor
The navigation dashboard pairs turn-by-turn maps and destination search with live vehicle gauges, so you can keep an eye on speed, RPM, coolant, fuel, and your check-engine status without leaving the road behind.
Works with your OBD-II adapter
Compatible with standard ELM327 Bluetooth OBD-II adapters and any OBD-II or EOBD vehicle (most cars and light trucks built from 1996 onward).
Perfect for
• Enthusiasts and tuners: live boost, timing, MAF, horsepower and torque, plus custom clusters and datalogging
• DIY mechanics: read and clear trouble codes, check emissions readiness, and diagnose issues at home
• Performance drivers: 0-60 and quarter-mile timing with saved run history
• Everyday drivers: a clean, beautiful digital dashboard that keeps you informed on every trip
