The controller you need is already in your pocket.

SpheroMind makes native apps that turn the iPhone and iPad you already own into precise, low-latency controllers for your Mac and PC. You get a racing wheel in your hand and a pen tablet on your desk.

Your iPhone is the steering wheel.

Hold your phone like a wheel and drive. Wheelio turns iPhone motion, pedals and buttons into a real racing-wheel or gamepad controller on your computer, over your local network.

  • Gyroscope-fused steering with 60°–1080° rotation and auto-centering
  • Analog gas and brake, plus A/B/X/Y buttons you can remap
  • 120 Hz output with a 250 ms safety reset if the connection drops

PencilBridgeiPad + Apple Pencil → Mac · Windows

Your iPad is the pen tablet.

PencilBridge uses Apple Pencil hover, pressure and squeeze as a wired pointer for your computer. It works for everyday work, for drawing, and for osu!-level precision.

  • Six input modes, from everyday pointing to competitive osu!
  • Wired over USB-C, so nothing goes over Wi-Fi or the internet
  • Handwrite with Scribble and type into any app on your computer

How we build

Small, native and honest about what it does.

Every SpheroMind app follows the same rules.

Latency first

Input paths are measured, buffered on purpose and tuned for 120 Hz, because a controller that lags is useless.

Local only

No accounts, no cloud and no analytics. Your devices talk directly to each other and nowhere else.

Truly native

Written in Swift for iOS, iPadOS and macOS, using standard Apple frameworks. Windows receivers are native too.

Tested on hardware

Automated tests cover the input math, and every release is checked on real iPhones, iPads and Macs.
