Been using this app for years mainly as a phonebook kind of thing. I could put a phone number in the app, and it would give me a business, or person name associated with the number. Recently, I can no longer use the app at all without allowing the overlay on incoming calls, which I can't stand that overlay because it blocks the contact name for a couple seconds until the app recognizes that its a contact, and not a spam call. Absolutely ridiculous. Don't pay for this app!

I was plagued by calls from 0843 and 0845 premium numbers. They would allow one ring, then hang up and expect me to call back and get a hefty charge. Since downloading this app, I have not been bothered at all. I can see from my call history that I've had a number of calls from these numbers over the past week, but the app blocked them before the phone actually rang. Highly recommended.

It works! I've tried similar apps like TrueCaller but they're pretty useless in the UK to be honest. This has flexible blocking options, such as blocking all 08- numbers, which allows me to stop a large number of spam calls with a simple rule. I only wish the logo was more like a phone symbol as it's a little bit out of place on my home screen !
