Thanks to application, you dont have to count and with the audio warning system you can always be sure enough lying on the ground while your doing push-up. Also you dont need response to touch your device.
Besides, when you open the radio or music player, the counter's warning audio wont be emotionless. Only you have to do approach the device while push-ups.
Any further information about the application you can check to the help page in the application.
