Blocks unknown calls and lets you check any number. If everyone had this app, scammers wouldn’t be able to get away with their tricks.

Wonderful app that does exactly what it’s supposed to. No annoying ads or useless features — and the number info is super clear. The free version covers all my needs. Honestly, I absolutely love it.
