Two Dashboard Styles, Live
Supported Hardware
One app for your entire powertrain.
Live HUD Dashboards
Two dashboard styles — a modern speed-hero HUD with a swipeable RPM/power/efficiency layout, or a full-gauge Racing/Glow style with a circular speedometer and range estimate. Real-time voltage, current, speed, RPM, temps, throttle, and power throughout.
Full Controller Tuning
Every parameter at your fingertips. Current limits, speed limits, gear ratios, regen braking, throttle response, field weakening, PID tuning, follow modes, TCS — if your controller supports it, you can change it.
Dealer & Hidden Parameters
Reaches deeper into a Fardriver controller than most tuning apps bother to — dealer-level and hidden registers included, not just the parameter set official apps expose.
Visual Curve Editors
Drag-to-edit RPM power curves and energy regen curves with gradient fills, Catmull-Rom smoothing, and saveable presets. See exactly what your controller will do at every RPM point.
Data Logger & Tuning Insights
Record any ride at up to 10Hz, then review it as a full session — multi-series graphs you can toggle per metric, plus automatic call-outs (like a throttle that never reached 100%). Export or share any run.
Battery Management
Per-cell voltage monitoring with min/max/delta tracking, pack temps, SOC, and cycle count. Charge and discharge MOSFET control right from the app. Full protection status at a glance.
Wear OS Companion
A free watch app mirrors live speed, battery, and temperatures on your wrist, with a gear indicator built in. Quick BMS charge/discharge toggles work straight from the watch — no need to pull your phone out.
Remote Controller Sharing
Host your live controller session and let someone else — a friend, a tuner — view and adjust it from anywhere over the internet, no local Bluetooth range needed.
Efficiency Tracking
Track a trip's Wh/mile consumption and estimated range as you ride, pulling from both the controller and BMS. Review trip history afterward to see how your riding style affects range.
Presets & 9 Languages
Riding mode presets (ECO / Street / Sport) with one-tap switching, plus save/restore for full parameter sets. Works offline with no account required, in English, Spanish, French, Portuguese, Russian, Turkish, Korean, Thai, and Chinese.

Frequently Asked Questions
What is the Worthless Controls Fardriver app?
Worthless Controls is a free Bluetooth tuning app for Fardriver FOC motor controllers, plus VESC and several BMS brands. It replaces plugging into a laptop — connect over Bluetooth from your phone to read live telemetry and change every tunable parameter your Fardriver controller supports.
Is Worthless Controls an official Fardriver app?
No. Worthless Controls is an independent, third-party app built to be compatible with Fardriver controllers. It is not affiliated with, endorsed by, or sponsored by Fardriver.
Which Fardriver controllers does it work with?
Any Fardriver FOC controller with Bluetooth (the NJ286 and similar Bluetooth-equipped models). If your controller has a Bluetooth module and you currently use a Fardriver app or laptop tool to tune it, Worthless Controls can connect to it.
Do I need a laptop to tune my Fardriver controller?
No — that's the whole point. Worthless Controls runs on your phone (Android or iOS) and connects directly to your Fardriver controller over Bluetooth, so you can tune current limits, speed limits, regen, throttle response, and every other parameter from wherever the vehicle is.
What's the difference between the two dashboard styles?
Modern is a live HUD-style speedometer with a swipeable RPM/power/efficiency layout, built for glancing at while riding. Racing and Glow are full-gauge styles with a circular speedometer, efficiency overview, and range estimate. Pick whichever reads best on your bars.
Can I record and review a ride afterward?
Yes — the built-in data logger records controller and BMS telemetry at up to 10Hz for as long as you like, then gives you a full session view with multi-series graphs and automatic tuning insights (like flagging a throttle that never reached 100%). Runs can be shared or exported.
Does it work with a smartwatch?
The free Wear OS companion app mirrors live speed, battery, and temperatures on your wrist, with a gear indicator and quick BMS charge/discharge toggles — no need to pull your phone out.
Is it free?
Yes, the core app and Fardriver tuning is free on both Android and iOS.
Requires Bluetooth permission to connect to your controller and BMS
