When a client uses another service that you have like CLARITY CHECK PLEASE ADVISE THAT THERE'S A COST INVOLVED. I checked up on my wifes number just to see what the outcome would be & was requested to pay. I am not interested, so there will not be any payment. Just downloaded to my phone. Have used the App b4 but didn't know that it could be used as a phone. Getting to find out who is on the other side is great. I can definitely recommend this App.

Very happy user. Downloaded this app and I have seen NO ads, and it blocked scammers on contact. Hardship loan scams, Medicare Scams, social security scams, everything. And I tried the free trial for the yearly version. Awesome! Way better than eyecon!

Scam, data leakage. Other person can get our data from other people.

Possibly good, but blocked two calls from work even tho tellows is set to not block any calls (android specifically says "blocked by tellows"), and the remind-to-rate box is really obnoxious and gets in the way (until you turn that off ofc). Since I can't have it randomly block calls, I have to uninstall.

Not consistent. Wrote a review about a number which really is a ping call and Tellows app would not update the record and shows "There are no ratings on the numbers yet". What the heck is going on here?

It could not block spam calls and yet always inaccurately shows junk calls from other countries, but actually, many times, when I picked up my cellphone to answer the calls, which were from my own town! However, I directly checked the numbers by browsing your websites, it would attempt to tell the sources of the suspected calls those were in my own town. Queer apps!
