If you forget to mute your phone and calls rings or notifications chime during important meetings or wakes you up at night, then this Do Not Disturb app (DND) is for you. Enable Calendar and Night mode, and forget about having to play with volume control to silence your phone.

Several features set this app apart from others in the category. This application was written with security in mind. As such, it requires just a few permissions to read user's contacts, calendar and to send and receive SMS. Most other apps require network permissions, and some need access to SD storage, which allows them to transfer any of the personal data from the phone unnoticed. This app can't do that, so you can rest assured that your personal data is safe.

This app offers the following features:

* It can silence the phone for the night and/or during office hour, meetings or calendar appointments
* Instant silent mode timer can be started with just 1 click,
* Instant timer can also be activated via the widget by the volume bar
* It can keep the phone on silent + vibrate all day and go completely silent for the night
* It mutes phone calls and all audible notifications during quiet time, except alarms
* Day and night time schedule can be programmed separately for each day of the week
* Calendar selection is configurable, and only Busy events are muted
* Supported calendars include Google calendars, Exchange
* SMS and call exceptions are supported while the phone is muted
* You can allow separate groups of contacts to ring at night and/or during the day
* Enable Emergency mode to let repeated calls from the same number ring
* Use No Exceptions mode to block calls from allowed contacts for the duration of an important meeting
* Use Respond via SMS to let the caller know to call back again if it's urgent
* Optionally disable Bluetooth handsfree during quiet time
* Cancel mute when you wake up early or the meeting ends early

Certain vendor phones have issues with vibrate mode. If your phone doesn't vibrate when you enable vibration in this Do Not Disturb app, change vibration settings in your phone's system settings/sounds menu.

Please don't block this app's notifications on your phone, it can cause the app to not work correctly. Also note that if you have a task killer/booster type of app installed on your device, add this Do Not Disturb app to the list of exceptions. Finally, make sure you don't have other apps that manipulate the speaker running at the same time.
