Navigation
A map that turns with the car.
Type a destination in the app's Navigate tab and tap Go. The phone works out the route and streams it to the gauge. Choose how it looks with "On the gauge: Map / Arrows".
Map
- Your route in your theme colour, drawn on a dark map with a compass ring.
- Turns with the car, north on the ring. Zooms out on the highway and in before a turn.
- Next turn and distance at the top, your speed and the posted limit at the bottom.
- The whole route loads when you start, so a weak signal on the way doesn't stop the map.
Arrows
- One big arrow for the next turn, and a smaller preview of the one after.
- Street name, distance, arrival time and miles left.
- Your speed turns red when you're over the limit.
Off route
The gauge shows Rerouting and the app finds a new route by itself. No taps needed.
Good to know
- Routes come from the AetherGauge app, not Apple Maps or Google Maps.
- Allow Location "Always" to keep guiding with the phone locked.
- Routes use OpenStreetMap data. You need mobile data to start a route and to reroute.
Engine data
Read the car, not a guess.
The gauge reads your car directly through the OBD-II port, many times a second. It only reads. It never writes anything to the car. In the app's Data tab, tap any slot on the preview to choose what goes there.
Readings
What your car reports depends on the car. A reading your car doesn't send shows "--".

Check engine
Know why the light is on.
- The gauge checks for trouble codes every 30 seconds. A new one shows CHECK ENGINE with the code and what it usually means, over any screen.
- Hide the alert from the app or the iPhone widget. It stays hidden until the codes change.
- App, Home, Diagnostics: tap a code for a plain explanation and how urgent it is.
- Clear codes after a repair: engine off, key on. Clearing doesn't fix anything, and it resets the car's emissions self-tests.
Recording & Performance
Log a drive. Time a pull.
Recording
- Tap Start recording and pick the readings you want. The gauge logs them 50 times a second.
- Watch a live graph while you drive, up to 60 minutes per recording.
- Review any recording later and export it as a spreadsheet file (CSV).
- Compare two: overlay two recordings, lined up from launch, with peak and average for each.
Closed course only
Performance timer
- Turn it on in Modes. Stop completely until the gauge says READY, then launch.
- 0-60 (or 0-100 km/h), 1/8 and 1/4 mile times and speeds. Accurate to about ±0.1 s. Not a certified timer.
- Every run is saved in Sessions, Runs. Share any run as a picture card for your feed or story.
The app
Six tabs. The gauge has no buttons.
Everything you'd do with buttons happens in the app.
Home
- Connect, and see the connection.
- Gauge remote: which screen is showing, change screens, and that screen's button.
- Diagnostics, weather, and quick recording.
Navigate
- Search an address or place, save favourites, start a route.
- Map or arrows on the gauge.
Modes
- Which screens you see and their order.
- Presets: Sport, Cruise, Minimal, plus two of your own.
Data
- A live preview of Data 1 and Data 2. Tap a slot to change it.
- Layouts, warnings, units.
Sessions
- Recordings and Performance runs.
- Review, export, compare, share.
Settings
- Theme, brightness, units, clock.
- Firmware update, reset.
iPhone extras

Texts, calls and app alerts on the gauge
- Pair the gauge with your iPhone once (the app walks you through it) and allow it to show notifications.
- New texts, calls and app alerts pop up over any screen with the app, who it's from and the message. The last few are kept on the Connection screen.
- The gauge reads them straight from the iPhone over Bluetooth. They never go through the app or the internet.
- To stop them: iPhone Settings, Bluetooth, tap (i) next to AetherGauge, turn off Share System Notifications.
Power & updates
Plug in and forget it.
When the car is off
- About 3 minutes after the engine stops, the gauge goes to sleep: screen off, very low power.
- It wakes when you start the car.
- Parking for more than a week? Unplug it.
Updates
- App, Settings, Firmware Update, then "Check for updates online".
- Keep the app open near the gauge with the engine running. It takes 2 to 4 minutes.
- If an update is interrupted, the gauge keeps its current software. Just try again.
