Getting started

What the app is, which wheels it understands, and how to connect the first time.

LoEUC reads what your wheel already broadcasts about itself and puts it on your phone screen. The app does not ride for you and decides nothing on its own: it shows, records and warns.

There are two builds, one for Android and one for iPhone. They do close to the same thing, and the differences are called out where they exist.

What you need#

A phone and a wheel. The app has no server, no account and no need for an internet connection.

On first launch the phone asks for permission to find devices nearby. Without it the operating system will not let the app see the wheel at all. On Android that permission is historically tied to location, so the prompt may mention your location even if you never intend to record a route.

Connecting the first time#

  1. Turn the wheel on and make sure nothing else is connected to it. A wheel holds a single connection, and while another app is talking to it, LoEUC cannot see it.
  2. Open LoEUC. On Android the search starts automatically and keeps running while the home screen is open.
  3. Find your wheel among the nearby devices. The app marks devices that look like wheels and labels the brand it thinks it found.
  4. Tap the row. The app connects, finds the right channels and starts showing telemetry.

After the first successful connection, the wheel stays under “My wheels”. On later launches the Android app notices it in range and chooses it automatically. You can keep several wheels; long-press one to give it a familiar name or remove it from the garage. Its factory name remains the identity used by rides, settings and alerts, and the name you gave it is what the dashboard header shows from then on.

Your wheel stays listed even when it goes quiet in the air — tapping it still connects by the saved address. And going back from the dashboard to the garage does not reconnect: the link holds and the ride continues, but the app will not pull you back to the dashboard until you tap the wheel yourself.

If the wheel does not answer, the usual cause is that it is still paired with the manufacturer's app or with another phone. Toggle the wheel's wireless connection off and on, or close the other app.

The home screen with saved wheels and nearby devices
The Android home screen keeps looking for a wheel; there is no scan button to start.

Demo mode#

You can try the app without a wheel. On first launch the demo button is on the home screen; afterwards it lives in the ⋯ menu. It plays back a prepared ride, and every screen behaves exactly as it would with a real wheel.
