tcSpeeds

Sailing Speed Instrument

Free · In‑App Purchases · Designed for iPad. Not verified for macOS.

tcSpeeds provides advanced knowledge of your current speed, average speeds, maximum speed, directional speeds, velocity made good, wind measurements, and much more. 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. For Wind measurement, you will need to acquire the Calypso Ultrasonic Wind sensor. More sensors will be supported in the future. 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.
