Should I Answer? – Android Call Blocker App

Get rid of the unsolicited calls once forever. Safely and absolutely free.

Telemarketers, phone scams or „just“ unsolicited surveys? The Should I Answer app can get you rid of all such calls.

How does the app work?

Whenever some unknown number calls the app checks it in its permanently updated database – immediately, without internet connection. If it finds out that other users reported the respective number as nuisance, it warns you against it. Or if you want it so, it can block it directly, the caller will not be able to reach you.

It is just the database used by the Should I Answer app which is an absolute unique part. It is composed directly by the users of the app: after each unknown call the users can rate it anonymously either as safe or spam. After approval given by our admins the report is then visible in the database where all users can benefit from.

What the app can do?

  • It can protect you effectively against the unsolicited calls. You can set the level of protection exactly according to your needs: from simple alert of unsolicited call to direct blocking.
  • It can block even hidden, foreign or premium rate numbers. Also, you can write your own lists of blocked or allowed numbers.
  • The app can be used as fully functional dialer app: you will find all your Contacts, favourite Contacts and complete call history in it.
  • The app can protect you even offline. If you need to update the local database it waits for your wi-fi connection.
