Have you guys ever missed an important call, just because you simply put your phone in vibrate mode?

What if your girlfriend or wife wants you but you don't recognize it?
What if your boss calls you but you don't answer it?
What if you win a great prize in lottery but miss the chance to receipt the money because of your phone vibrating?

This App gives you an answer. This App can register up to 10 phone numbers that you consider as so important.
When you get a call from one of registered numbers, your phone rings even though you put it in vibrate or silent mode.

Other scenario:
If you are looking for a mighty call block app, this also is recommendable.
Suppose you are very tired and want to take a rest, and don't want others bother you.
You may put your phone in silent mode, with some important phone number registered as "Must Answer"
In this scenario, "Must Answer" acts like kind of whitelist-based call block.
There are many blacklist-based call block apps in the market. But this is the reverse. This will help if you want to block almost all calls except a few importants.

Usage:
At first, launch the app,
and then, register one or more phone number(s) with description(s),
at last, watch registered number(s) listed up, close the app.
It still will work even if you close the app.

How to register?
Tap (+) button at upper left corner.
or
Tap 'menu' button and then tap 'Register number' menu.

!IMPORTANT!
It is totally your responsibility to use this software that may cause unexpected result at a theater, church, library or etc.
