This is the paid version with no ads for the popular Call-Waiting Ringer app free version. It works the same as the free version but no wearable app attached. Please test out the free version first and if satisfied try this version. Works the exact same way only there should be no ads. Final sale.
Plays a sound or vibrates when a call waiting is received. Also new feature you can now play a ringtone on a outgoing call. When you speak into the mic the sound stops.
Very convenient way not to miss a call-waiting when there is loud noise nearby. It works for text messages during a call-waiting too. Very easy and clear setup and user interface. Even a child can figure it out. Also makes your android watch vibrate on a call-waiting.
note: Please use as is and there is no guarantee etc.
