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). SUPPORT Questions or ideas? Contact: support@takasawadynamics.com
