EUC Logger vs EUC Pro

EUC Logger is a live telemetry dashboard and a black box for your electric unicycle. Connect over Bluetooth and ride: the app shows what the wheel is doing, warns you out loud when it matters and writes the ride to a file by itself. Afterwards, take it apart on charts and a map, or put its numbers onto your video. WHILE YOU RIDE • 33 wheel metrics as tiles — speed, PWM, power, voltage, currents, charge, temperatures, lean, odometer, both BMS packs — each with a chart and session min-max • The dashboard learns your wheel: tiles it never fills hide themselves; a missing value is a dash, never a zero. Pinch to resize, hold to reorder, swipe between pages • When the link drops the screen says so: dashes and a gap in the chart, not frozen numbers • The same dashboard runs on Apple Watch WHAT IT WARNS ABOUT • Twelve kinds: PWM, speed, lean, motor and battery temperatures, both currents, two levels of low charge, tyre pressure (InMotion), link lost and restored. Thresholds are per wheel; PWM is on from the start, at 80 % • Each kind has its own sound, so you know what fired without looking; your own spoken phrase can replace it • Audible with the silent switch on and the screen locked; other audio is ducked only while an alert sounds • This adds to the wheel's own tiltback and beeper, not replaces them RECORDING RUNS ITSELF • No start button: the file opens itself; a dropped link or a relaunch does not end the session • One row per telemetry frame, 2 to 20 a second depending on the wheel • 63 CSV columns, the first ten exactly the DarknessBot layout, so analysers of its logs open the file • Share a ride as a file with a privacy zone around home, sealed by the phone's secure chip: the receiver sees if it was altered. Trim a spare piece into its own file AFTER THE RIDE • Charts: up to three metrics at once, pinch to zoom, hold for a ruler, landscape for full screen; line, area or bars, and a break where telemetry went silent • The route on a map, coloured by speed, with ride playback. On a track the app finds laps itself, times them and shows the best one • 0–60 and 0–100 km/h from a standstill, or your own pair of targets — by the wheel, GPS and dragy, every run of the ride in a table • Heart rate from Apple Watch: a column, a tile and a chart TELEMETRY OVER VIDEO • A clip plus your recording — numbers land on the frame: tiles, bars, sparklines, speed and lean arcs • Where the footage runs past the recording or the link was silent, the plate shows a dash • Show the app's sync QR code to the camera, and the clip lines up with the ride by itself • Projects are saved. Export up to 4K, H.264 or HEVC, Reels and YouTube presets YOUR WHEELS • Each wheel keeps its own thresholds, layout, name and archive; a wheel that is off opens as a frozen dashboard • Six protocol families. Three verified on hardware we own: InMotion V2 (P6), Begode-compatible (SV168), Veteran-compatible (NOSFET Aero). Three more — KingSong with Rockwheel, InMotion V1 (V5–V10), Ninebot Z — decoded from open sources and riders' captures • Your wheel not listed? Connect anyway: the protocol is recognised from the wheel itself • The app changes nothing in the wheel. Exception: SmirnoV firmware settings, balance tuning behind a warning • An optional dragy DRG71 (Pro) GPS meter is read alongside: speed, g-forces, coordinates • No wheel at hand? Demo mode behind the gear icon runs the app on a simulated ride PRIVACY • Free: no accounts, no ads, no analytics, no third-party SDKs • Rides stay on the phone; optionally copied to iCloud Drive • Location is used for speed and route: both go into the ride file and onto the map. Map imagery comes from Google's static maps — only the shown area goes into that request • Each closed ride's seal — no ride data, no location — is registered on euclogger.com; this can be turned off. Diagnostic reports leave only on your command iPhone, iOS 17+; watch dashboard needs watchOS 10+. English and Russian. Metric units only. euclogger.com

EUC Pro connects to your electric unicycle over Bluetooth and shows what the wheel is doing while you ride. Live Speed, power, PWM, battery and temperatures, updated several times a second. Set your tilt-back speed, switch the headlight and ring light, and sound the horn from the app. Rides Every ride is recorded with GPS. Open one to see the route with your speed painted onto it, charts for speed, power and regen, how much battery you used and how hot the motor got. The month view adds up distance, time and energy. City Heatmap All your rides on one map. Roads you ride often glow brighter than roads you've only ridden once. Apple Watch Start and stop rides, read speed, battery and power, and control the lights and horn from your wrist. Lock screen A Live Activity keeps the current ride on your lock screen and in the Dynamic Island. Rides are stored on your phone and in your own iCloud, so a new phone or a reinstall doesn't lose them. There is no account to create and nothing is sent to us. Built for the V9 and other wheels that speak the same Bluetooth protocol. EUC Pro is an independent app and is not affiliated with any wheel manufacturer. Save rides to Apple Health as workouts, with heart rate and calories from Apple Watch. Free to try: record 3 rides free, then unlock unlimited recording with a one-time purchase. No subscription.
