Worthless Controls vs BMS by GDriver

Worthless Controls is the most complete tuning and telemetry app for electric-vehicle motor controllers and battery systems. Connect over Bluetooth and take full control of your build — whether you ride an e-motorcycle, scooter, e-bike, or e-skate. CONTROLLERS • FarDriver — full parameter tuning • VESC — profiles, live data, and configuration • VOTOL — telemetry and parameter editing BATTERY (BMS) • JBD, JK, ANT, DALY and more — voltage, current, SOC, cell balance, temps, and protection status at a glance LIVE DASHBOARDS • Full-screen race dashboard: speed, RPM, power, temps, and trip data • Classic gauge dashboard with multiple styles • Optional GPS speed and real-time charts TUNE EVERYTHING • Speed, current, regen, throttle response, field weakening, and dozens more parameters • Edit RPM and torque curves visually • Wheel-size and battery calibration for accurate speed and range RECORD YOUR RIDES • Data logging with configurable metrics and CSV export • Log viewer with charts and a GPS map of your route • Efficiency tracking and range estimation AND MORE • Flash controller firmware (.bin/.hex) right from your phone • Remote sharing — let a tuner adjust your controller from anywhere • Drag and lap timer with a leaderboard • Connect multiple devices at once Some advanced features require a one-time Pro unlock. No subscriptions, no ads — buy once, yours forever. Not affiliated with FarDriver, VESC, VOTOL, or any BMS maker. Adjusting controller parameters and flashing firmware carries risk — use at your own discretion.

BMS by GDriver provides full ANT BMS integration and telemetry monitoring for compatible JK, Daly, and JBD battery management systems. FULL ANT BMS INTEGRATION Connect to a compatible ANT BMS over Bluetooth for live telemetry, guided battery setup, parameter reading and configuration, and BMS controls such as charging, discharging, and balancing. TELEMETRY FOR JK, DALY, AND JBD BMS Connect to compatible JK, Daly, and JBD BMS hardware for read-only telemetry monitoring, session logging, and battery insights. Parameter configuration and BMS controls are available only for ANT BMS. COMPATIBILITY Compatibility and available features can vary by BMS hardware, Bluetooth module, protocol, and firmware. LIVE BATTERY DASHBOARD Follow pack voltage, current, power, state of charge, cell voltages, voltage spread, temperatures, protection states, and other data exposed by your connected BMS. LOCAL LOGGING AND INSIGHTS Record battery sessions on your device and review the latest completed session and its core summary for free. See duration, sample count, maximum power, widest cell spread, and the fault timeline without BMS Pro. BMS PRO — A SEPARATE ONE-TIME PURCHASE Unlock full log history, deeper report metrics, charts, cloud analysis, and future premium insights with BMS Pro. BMS Pro is a one-time purchase for this app and is separate from GDriver Pro in the Ride app. READ-ONLY DEMO MODE No battery or account is required to explore. Choose Explore demo on the sign-in screen to open a deterministic connected ANT pack, live telemetry, and an 18-minute sample log. Demo mode is read-only and does not upload data. OPTIONAL NOTIFICATIONS Enable low-battery and battery-health alerts when you want them. Notification permission is requested only after you choose to enable notifications. Bluetooth access is required for live BMS connections. BMS by GDriver does not request location access.
