The raceQs tracker app records sailing data with a phone and creates a 3D replay of a user's race online. Check out the demo! The 3D replay will show the user's boat and any other boats that were recording in the area. Users can select anyone in the replay to learn from the top performers in the fleet or watch the replay with their crew and evaluate their race in the club and at home online.

The raceQs app is more than just a tracking device. It also records the motion of a boat using the accelerometer and gyroscope in a phone. By watching a detailed replay of the race, users can evaluate their tacking patterns, boat handling, heel angle, and more to improve their future performance.

raceQs was originally developed with the Google Earth plugin and is now migrating to Cesium.
