Unwanted telephone calls? That's annoying! It's a big hassle to have to go through the hassle of ignoring them, or worse: wasting time trying to get through to the person who called.

If you want to make sure that you never make such a mistake, or if you just don't want to deal with the hassle of ignoring unwanted calls, you should download the Should I Answer app.

The app will help you to keep track of all the calls you receive, and if it finds out that you're ignoring a call, it will immediately notify you about it. It will also allow you to block the number directly, so the person calling you won't be able to reach you.

The app can block premium rate, foreign, and unknown numbers.
