The description of Should I Answer?

Should I Answer is free mobile security application protecting you against unsolicited, expensive, unwanted or unknown calls.

Should I answer the call? This question can come into a mind of every person who sees an unknown incoming call. Each of us had (or will have) the opportunity to face the unsolicited call, telemarketing campaign, advertisement or some kind of fraud call. How should we find out that the calling number is harmless and answering it will not cost us tens of minutes of precious time or significant amount of money?

FAQ

How is the database of ratings and numbers created?
The database is built-up by the community of all users who have the application installed and/or visiting the application pages. The users can anonymously send ratings and reviews for public phone numbers (we do not collect info for private numbers) based on real answered calls. These ratings are stored in central server database where our admins can check them and after evaluation and approval the reviews with ranking are then distributed to all mobile phones with our application installed.

Why the application demands access to contacts and phone calls in my mobile?
Such information are used by the application to distinguish between your private contacts stored in your mobile and new incoming calls – so the rating form is displayed only for new not rated/not private numbers in your history. Your private contacts are never sent to server (generally speaking they never leave your mobile).
