EUC Planet is an open-source companion app for electric unicycles. Buying it here supports ongoing development. The same APK is also available for free on GitHub if you'd rather sideload — both builds are identical. No ads. No subscription. No account. No telemetry phoned home. It connects to your wheel and stays out of your way. LIVE TELEMETRY • Big speed dial with optional rainbow color band tied to your safe / warn / danger thresholds. • Live battery, voltage, current, PWM load, temperature, trip distance, odometer. • Tap any tile to jump to its historical graph. • Metric, Imperial, or fully custom units (knots, Norwegian mile, Celsius — mix and match). TURN-BY-TURN NAVIGATOR • Multi-stop route builder on a map. Drop, drag and reorder waypoints. • Walk / bike / car / straight-line routing modes. • Live guidance with voice cues, off-route recovery, and a Treasure Hunt mode for unmarked destinations. • Routes survive a kill of the app; resume right where you left off. OVERLAY STUDIO • Records phone-camera video with a fully tunable on-screen telemetry overlay: speed dials, gauges, rolling graphs, free-text tiles with {speed}-style variables, mini-map, badge, layered cameras. • Save layouts as JSON presets. • Export plain MP4 for the final clip, or transparent overlay only for compositing on top of footage shot with a GoPro / drone / second camera. WEAR OS COMPANION • Tested on Galaxy Watch Ultra; runs on any Wear OS 5+ watch. • Full-bleed speed dial, three batteries (wheel / phone / watch), horn + light + voice controls on the wrist. • Next-turn arrow mirrored from the phone navigator. GARMIN WATCH • Speed, battery, PWM, temperature and distance on the wrist, across 138 Connect IQ devices. • Connect IQ Store, or sideload the .iq from GitHub. HOME SCREEN WIDGETS • Speed, trip and charge, plus one-tap horn, light and lock buttons that follow the wheel's state. PICTURE-IN-PICTURE • A floating window when you leave the app: a simple four-reading face, or your own dashboard layout. PHONE HUD • Any Overlay Studio layout drawn over other apps, so the wheel stays visible while you use maps or music. HELMET HUD • Streams telemetry to a Motoeye E6 or similar Android helmet display over your hotspot. REAR-VIEW RADAR • Garmin Varia pairs straight to the app: approaching traffic with distance and closing speed. SMART ALARMS • Define your own threshold-based alarms on speed, battery, temperature, PWM, voltage, current. • Each alarm independently fires beeps (custom tones), voice ("Battery at {value}%"), and / or vibration. • Cooldown and repeat-while-active so alerts don't spam. VOICE & ENGINE SOUND • Periodic spoken reports, configurable rate and locale. • Special-event announcements (lock / unlock, lights, GPS fix, legal mode). • Optional engine sound that scales with speed. TRIP RECORDING • GPS + telemetry logged in DarknessBot-compatible CSV. • Auto-record on connection. • Compare any past ride against the live one, side by side. INTEGRATIONS • Flic 2 buttons for horn / lights / lock / voice without touching the phone. • Volume keys as extra shortcuts. • External BLE GPS (RaceBox supported) for centimetre-class speed and altitude. PRIVACY • Local-only. No analytics SDKs. No ad IDs. No call-home. • Optional cloud sync goes to a folder YOU pick through Android's storage picker. • Full source code on GitHub. WHEEL SUPPORT Verified: InMotion V14 (50GB / 50S), P6, V1 family (V5 / V8 / V10). Preliminary: InMotion V12 (HS / HT / Pro). Preview (built from public specs, real-hardware testers wanted): KingSong S22 / S20 / S19 / S18 / S16 / F-series, Begode Master / RS / EX / MSX / Hero / Mten, Veteran Sherman / Patton / Lynx / Abrams, Ninebot Z / legacy. Help support your wheel: connect, file a wheel report through the in-app banner, or capture a labelled BLE session per the guide on GitHub.
