Why is this audio recorder application good for you?1. The screen will be all black like when the phone is turned off. (No one will know you are recording)2. Touch anywhere in the screen.(vibrating 1 time = start recording vibrating 2 times = stop recording and saved)3. [ save folder : /sdcard/BlackRecorder/filename(day+time)]4. The screen will be never turned off if you do not turn it off.Thank you and have fun with it!!
