Is the Should I Answer app really blocking spam calls? Here's how you can tell

The Should I Answer app is a useful tool. It recognizes incoming spam calls and according to your preferences, it either warns you against them or blocks them completely.
How does the protection work?
The Should I Answer app uses its own database of spam numbers. This daily updated databases has three sources: all numbers reported to Do Not Call Registry, all numbers reported to Federal Communication Commision and, most importantly, all community reviews from the Should I Answer app and from our website. Nowadays, the app grows by 30 000 new reports every day.Whenever an unknown call comes, the app looks into this database. If it finds out the caller has been reported as “spam”, it warns you before you answer the call. You can also set the app to completely block incoming spam calls (in the app’s Settings).
