BlockList is an easy to use app that helps you to avoid unwanted calls from unknown numbers or contacts from your phonebook.
With just a few taps you can block everyone with the exception of the contacts you want to speak with.
*   Block everyone
*   Block everyone except the exact people whose calls you want to receive
*   Block just unknown numbers
*   Customize and store exception lists for easy activation
*   Set time period for blocking
*   Send auto SMS to blocked callers
*   See whose call was blocked and time of call
*   Activate 2 or more exception lists at the same time - PRO VERSION
There are countless times when you can use BlockList but here are some examples:
*   When you're sleeping but still want to be able to receive that important call, you can block everyone except for that one contact (but remember to turn off your phone's notifications too!).
*   Block only unknown  numbers, to do that deselect all your contacts from blocking and turn on "Blocking service". ( Unknown numbers are blocked whenever blocking service is on).
*   If you're a taxi driver, you can set up auto SMS to say something like: "Hey I have a passenger. Call you later." BlockList will send an immediate SMS to the contacts who tried to reach you while you were
busy giving a ride.
*   Roaming
*   Avoiding people  (stalkers/mother-in-law, pesky exes)
*   At the movies
*   On a date
*   In class
*   While driving
*   Bust meditating...
   ....and so on.
