I trolled, I don't know how to get information from arduino/hc-05 to the app. It must receive three values that correspond to three figures and when it sends the signal it must increment its counter. Furthermore I have to put 2 timers, the first from when it is started and the other must be from when the last signal of the figure arrived. The blocks I have placed so far are these:
