Telemetry as it happens
Speed, PWM, voltage, currents, power, temperatures, lean angles and distance. Whatever the wheel is willing to report.
Android · iPhone · Wear OS
LoEUC reads telemetry over Bluetooth, records rides, shows battery data and warns you while there is still headroom left. LeaperKim, NOSFET, InMotion, Begode, KingSong.
The short version
Speed, PWM, voltage, currents, power, temperatures, lean angles and distance. Whatever the wheel is willing to report.
Pick the tiles you want, drag a corner to resize, reorder them. Gauges, numbers, charts and a map on one screen.
Ride history with a chart per metric, a GPS track on the map, and a summary image to send to friends.
Voltage of every cell, the spread between them, temperatures, charge and discharge currents, capacity and cycle count.
Any metric, your own thresholds, your own logic. The sound is built step by step instead of picked from three presets.
Settings are written straight from the app and saved as presets you can hand to another rider.
What it looks like
Taken on real wheels. On Android the app takes its colours from the phone's system theme, so yours will differ.
Download
The app is free, has no ads and no server of its own: your data stays on your phone.
Installed through TestFlight, Apple's app for test builds.
An Apple account is required
A direct download. Android will ask you to allow installs from this source, which is expected.

Wheel support
A straight answer about what has been confirmed on real wheels and what comes from reverse engineering and still needs checking.
Every brand and every field in detail: the wheels section
Write to me. Adding a model needs a capture of the conversation with the wheel, which the app records itself, plus a couple of known readings from the wheel display to check the decode against.
