Equepoise apps help you achieve optimum equestrian riding posture using real time measurements from Equepoise Riding Sensors. Specifically this app helps you achieve perfect upper arm posture by constantly monitoring your elbow position and alerting you if your elbow starts moving out from the side of your body beyond an alarm limit. You can set your own preferred alarm limit when you calibrate the system. You can easily adjust it at any time to suit your training regime. You also have control over the alarm reaction speeds - 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.
