Equepoise apps help you achieve optimum equestrian riding posture using real time measurements from Equepoise Riding Sensors. Specifically this app helps you achieve a perfect upright head posture by constantly monitoring your head position and alerting you if your head starts tilting too far forward or backwards. You can set your own alarm limits when you calibrate the system. You can easily adjust these at any time to suit your training regime. You also have control over the alarm reaction speeds. So, for instance, beginner riders can set Equepoise to tolerate momentary lapses in position whilst experts can make it react sharply. Alert sounds can be combinations of tones and spoken words. A feature of the app is that you can record your own sounds to suit your particular requirements. The app also features a simple user interface designed to maximise contrast in sunlight and to be easy to use when you are mounted on a horse. The app can record your results after a ride and graphically track your improvement over time.
