Thankful for free trial

Downloaded it. Started free trial. Selected it in my phone settings. Zero change in the number of spam calls. Unless my app didn't fully load, there are no settings, no calls blocked list, no ability to add numbers to block next time, no indication it is even doing anything , just the screen to start the free trial.

UPDATE::: The app developer is quick to provide help and was able to get the app working properly. So far so good and it is identify spam calls both live and in my recent calls list.

Does nothing

Downloaded this app. Thought for sure since it said it works with iPhone s it might just work! Had high hopes... Did everything it said to do and I can't get beyond the screen that says "try it free for 1 mo...start free trial now". I did that and it says "you're currently subscribed to this" yet it takes me back to the same screen and does nothing. I've rebooted my phone, I've uninstalled the app and reinstalled it and get the same thing. Yes the call blocking and identification is turned on to it! I have had to decline 6 calls in 2 hours today and manually block them myself. I'm glad I didn't pay for this app!!

I'll wait and see

Had a long negative review that I just erased. The app wasn't working for me. However I just got the app working.
Not sure how it performs yet. Will update once i know.

Just a note to developers, there is a bug if you try to sign in to your Apple account In app and get the password wrong. The app after that didn't ask again for my Apple credentials again. It instead just gave me the spinning wheel of death when trying to activate through the restore purchase button.
