คำอธิบาย Service Please

Installing this app on two or more Android devices on your WIFI network gives you the ability to summon the owners of those devices to attend to your every need.
Designed to 'motivate' someone to come to you no matter what they are doing, the app features three motivational ringtones, flashing alarm text and bell animation and most importantly, YOU control deactivation of the alarm (once your need has been met).
Great for around the house and office!
