iPhone
Live OBD2 data, custom dashboard, speed and RPM painted on the map, HUD, trip fuel economy, and engine sound driven by your real RPM. Pro adds no ads and unlimited logs.
See — and hear — your car in real time.
Connect an ELM327 Bluetooth (BLE) adapter and the app turns live OBD2 data into a fast, modern dashboard: RPM, speed, coolant, throttle, fuel, and every sensor your vehicle supports, auto-detected. No subscription. Ever.
WHAT MAKES IT DIFFERENT
• A genuinely modern interface — not the dated look of most OBD apps
• A one-of-a-kind engine-sound simulation driven by your real RPM
• Speed and RPM drawn on the map, color-coded (satellite view included)
• Buy once for Pro — no monthly fees, unlike many scanners
BUILD YOUR OWN DASHBOARD
Mix and match four widget types — digital tiles, analog needle gauges, live charts, and the trip map — then reorder them into your own instrument screen. A mirrored HUD mode projects your speed onto the windshield at night.
FIVE FOCUSED TABS
• Dashboard — your own widget layout, plus HUD mode
• Data — every live sensor, overlaid or separate charts, CSV export (long or spreadsheet-friendly wide format)
• Drive — trip computer with fuel economy, the color-coded track map, a G-force ball, and 0–100 timing
• Engine Sound — procedural sound that follows your real RPM (all presets free)
• Tools — adapter info and communication log
FREE INCLUDES
Live data, the dashboard, track map, trip computer, HUD, and engine sound — free, with a small banner ad.
PRO (ONE-TIME PURCHASE, OPTIONAL)
• Unlimited CSV logging
• Save your 0–100 and G-force runs
• Remove ads
Prefer just no ads? A cheaper ad-removal-only purchase is also available.
NO ACCOUNT NEEDED
Your vehicle data comes straight from the ELM327 adapter over Bluetooth and is processed on your device — there is no developer server collecting it. The free version shows ads served by Google's ad SDK (buy Ad Removal or Pro and no ads are shown). Try it with no hardware using the built-in demo mode.
REQUIRES an ELM327-compatible Bluetooth LE (BLE) OBD2 adapter and a vehicle with an OBD2 port (most cars sold since 2008).

Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
Unit support: gauges now read in mph, °F, psi and mpg based on your region (you can also switch manually in Settings). CSV exports follow the same units, with the unit written into the column header.
• Vehicle profile: set your tachometer range, redline and fuel type (gasoline/diesel). Fuel economy is now estimated correctly for diesels.
• When an adapter will not connect, the connection screen now explains why and what to try, plus guidance on choosing an adapter.
• Start and stop recording, and see recording status, from any tab.
• Gauges that have stopped updating are now clearly marked.
• The screen stays awake while the HUD is showing, and brightness is raised automatically.
• Settings have been reorganised into standard sections, with technical details and the communication log moved one level down.
• Fixed decimal separators for German, French and Spanish.
• Fixed layout problems at large text sizes.
