About
This app provides live telemetry and logging for electric unicycles. It displays real-time wheel metrics, offers customizable audio alerts for critical events, and automatically records ride data for later analysis on charts and maps. Enhance your ride videos by overlaying telemetry data.
What's New in EUC Logger

Battery watch • Pack failure watch: the app follows the current, the spread between packs and the garbage a failing BMS starts reporting, and warns you with a plate and a spoken phrase when a pack drops out mid-ride. The battery tiles light up with it. • Cell watch while charging through the GB/T adapter: a cell going bad is caught before the BMS starts reporting phantom 5 V. The demanded current falls to 5 A, the app names the cell and tells you what to do next. • Cell black box: three hours of every cell's voltage in memory, twenty minutes written to disk on an event, plus a charging log — you can see which charge went clean and which did not. • Charge is counted honestly: by the weakest pack that still answers, and the percentages come from the BMS themselves. On the Veteran V14 the charge that read half of the real one is fixed, and battery temperature now comes from all eight sensors. Map and track • Bead chain: a long press on the label-style button covers the track with marks — one per telemetry frame, each with its value inside. The size is set by the "−/+" buttons under the map: the smaller the bead, the denser the chain. • The time axis on the charts switches with a tap: time from the start of the recording, or clock time. • Route thumbnails in the list now catch up with a recording still being written. Dashboard and charging • A new "Avg speed" tile — the average speed of the ride, on the phone and on the watch. • The dashboard no longer stutters on long recordings. • Voltage and current ceilings for the GB/T adapter belong to the wheel named on the screen: until now the screen of an archived wheel edited the ceilings of the wheel on the link. Smaller things • "Max heart rate" in the ride summary catches up with the data Health hands over late. • The bar menu on the charts is one choice out of three instead of two tied switches. • P6: roll and pitch from the turbo frame. Wheels named E25 are recognised as the V9.
