It is an application for listening a practice of the Morse code.
Although the speed of the Morse code is two kinds, levels including the similarity of a reply are three. (EASY/NORM/HEVY)
It begins from "HR HR BT" and finishes it as "AR."
By three character units, an audio output is carried out automatically.
Please touch the right character string quickly out of three candidates displayed under a screen.
If it does not touch, it will time out automatically.
Android2.3.4:HTC/3D EVO, GALAXY S II WiMAX(2.3.6) were OK.
(I will try to fix for other Android version.)
