About this app

The BCD clock that displays Hours, Minutes, and Seconds .The bottom row in each column represents a “1” (or 2 to the power of 0 ), with each row above representing higher powers of two, up to 2 to the power of 3 (or 8).

The first two columns represent the hour, the next two represents the minutes  and the last two represents the seconds.
All binary digits of the clock are outlined in blue, A bit that is “1” will be orange, a bit that is “0” will be black.

The clock can be used in 12 or 24 hour format , and
can be stopped in order to more easily understand the binary positions of time.

The clock also has a chime mode which will ring a bell on the hour every hour if chosen

NRFPT Only displays in landscape mode, and the controls aren't working. I can't start/stop the clock, or change between 12 and 24 hour display. The ✅ beside "Chime" comes and goes. but I don't know if that actually turns the chime on and off. This is a Galaxy Note9 running Android 10 and OneUI 2.5. Once complete, I'm hopimg this app will allow turning off elements like the surrounding box, the time in 12:34 format, and the explanatory bit strings below the time. This is a very good start.
