tcSpeeds enhances your cockpit instrumentation for sailing, power boating, cruising, kayaking, paddle-boarding, driving, or flying airplanes recreationally or professionally.

tcSpeeds provides advanced knowledge of your current speed, average speeds, maximum speed, directional speeds, and much more. In addition, you will be able to measure your performance on a straight course with our proprietary Pilot Performance Index (PPI) computation. Compare how good you are at the controls with your friends or against your autopilot.

tcSpeeds stands on its own and does not require external hardware or connections to operate. tcSpeeds uses your device's own internal GPS, accelerometers, and compass.

Easy to use and conceived to minimize operational burden on the user, because we know you have other things to do. Zero setup required: install, launch and tap the start button.

Designed for iPhones, and GPS-equipped iPads.
