App works good for me ...Pixel 3a xl. Share function works good. Had for approx. 4-wks now. One problem is sometimes voice gets "hollow" sounding on my end. Called party also has noticed a few "sound" problems in same area. This happens 2-3 times during call, but not evderytime... but enough to be of concern for me.But I do like and suggest trying out. I do not use the paid version at this time.

Not much to it, simple and straight forward. Just installed a few days ago, i do get quite a bit random numbers calling me. But while yes, this app allows me to block, report and comment on the numbers, not once has this app showed me who was calling or had reports on any of the numbers that have called. Ive havnt gotten a hit on any numbers that ive searched yet either. Ill give it another week or so, but as of now, im finding it pretty pointless. *Free Version*
