iPhone
Forty-five dashboards, engine notes recorded from real cars, and every drive mapped and kept. No adapter needed. It works with the iPhone you already have.
Mount your phone and your car gets the instrument cluster it never had.
RevLine turns an iPhone into a proper digital dashboard, forty-five of them,
in fact, with engine notes cut from recordings of real cars, and a record of
every drive you take.
WORKS WITH JUST YOUR PHONE
No adapter. No wiring. Nothing to install in the car. Speed, heading, g-force,
distance, 0–60 and your cornering and braking forces all come from sensors your
iPhone already has. Mount it, start a drive, and it works.
FORTY-FIVE DASHBOARDS
Eighties digital bar graphs. Modern hypercar screens. Wedge-era binnacles with
orange needles. Clean Scandinavian minimalism, ink-on-paper, neon, and a set
that reacts to how you drive — rev hard enough and things happen.
Each one is drawn from scratch and laid out for a landscape phone, so it fills
the screen instead of sitting in a corner. Swipe to change. Tap to pick another.
ENGINE NOTES FROM REAL ENGINES
The sounds are not synthesised. Each is cut from recordings of the car or bike
it's named after — a naturally aspirated V10, a flat six, a twin-turbo V8, a
999cc inline four that revs to 14,000 — then rebuilt so it follows your revs
and answers the throttle. Lift off after a hard pull and it pops and crackles.
Play it on your phone or through the car stereo.
PLUG IN AN ADAPTER FOR THE REAL NUMBERS
Any Bluetooth or Wi-Fi OBD2 adapter turns the estimates into readings straight
off your car's own bus: engine rpm, coolant, oil and intake temperature, boost,
throttle position, engine load, battery voltage, fuel level and more. The
gauges swap over automatically.
It is an upgrade, not a requirement. Everything above works without one.
EVERY DRIVE, REMEMBERED
Drives longer than a minute are saved with their route, top speed, best
acceleration and hardest corner. Look back at any of them on a map. Build a
streak, climb driver levels, and see how your week looked.
BUILD YOUR OWN
Not quite the layout you wanted? Drag the gauges where you want them, save it,
and drive it.
YOUR DATA STAYS ON YOUR PHONE
RevLine has no accounts, no servers and no analytics. It makes no network
requests at all. Your drives and routes are stored on your iPhone and nowhere
else, and deleting the app removes them.
DRIVE SAFELY
RevLine is for entertainment and general interest. Its readings are estimates,
not certified instruments. Set it up before you move, mount your phone securely,
keep your eyes on the road, and obey every speed limit and traffic law.
