This app is designed to do synchronization and configuration with a Bluetooth connected device called Penguin. Penguin, meanwhile, is a swim timing pad for multiple swimmers training in the same swim lane, equipped with motion sensor allowing users to record the swim timing with the touch of RFID ring. The app will do basic function such as sending and receiving BLE data, store them internally and externally, and allowing swim club/coach to review the data of their students. It is also used to configure the students information and training program by the coach.
