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!

This app use to be great. It would block unwanted calls or text. I loved it. It cut down on robot calls tremendously. However it seems like it is letting these blocked calls get thru to voice mail rather than simply hanging up on them. It's happening more and more. Just had 5 such calls get thru in last two days! Come on guys.... don't let this app go down the tubes. Please fix this. Also... now you want to charge me to identify calls when it's been a FREE feature for so long. Are you kidding??

I was using this when it had full features for free. Then slowly things started changing and names were not included in the notification, but if I wanted to pay for it could. Received a notification that your service is no longer free. Thanks for that, you know, since I've been using your app for years.... You guys are not the only blockers out there. Not a very nice way to treat the people who recommended your app to others, and now you want money for a service that has gone downhill over the last few months.
