About PYNsync
PYNsync allows you to exchange text between two Android tablets.
To do this, first call PYNsync on both tablets.
After this, PYNsync must be started as "DUX" on the first tablet, PYNsync must be started as "COMES" on the second tablet. This must be done by synchronously pressing the red (DUX) button on the left at the first or the green (COMES) button on the right of the second tablet.
