For some scientific study, I need some automation. As a result, I need an iPhone app (with a watch app) that when switched on from the watch, it starts reading from motion/voice sensor and perform some analysis (just a mean value per 5seconds for now) and returns the number to the watch. It should also read out the calculations (simple vocal outputs). Also, give some feedback if the watch loses connection to the phone. A simple but functional interface (UX) is needed for both watch and phone.
