Seems to be highly accurate. It doesn't block calls, (which is a benefit for me); instead a rating comes up based on previous user experiences with the phone number. You can read detailed info if a person leaves an in-depth review, which is very helpful. You also don't run the risk of a call being incorrectly blocked (ie a call responding to a job application). It's accurate and the user input adds the extra info that is beyond helpful. Highly recommended

Hello Michelle, thanks for your nice review. In the free version you can block single numbers (if you want), when you are on the number overview page. Otherwise the caller ID alone is helpful enough to decide whether to pick up or not. Lots of fun with the app. Your tellows team

Call came in just now... Tellows did nothing. No popup. No information. Nothing. Had this app installed, set up and logged in for a week (yes it has all permissions granted that it asked for, and there was a strong & working Internet connection with the call came in). Whilst the idea seems sound, the app seems pretty useless to me.

Hello Hedgie, thanks for the feedback. The app should show a overlay while receiving an incoming call. Please make sure that you have battery optimization disabled (this may prevents the app from being active in the background). If you still encounter problems, send us a mail to kontakt@tellows.de, so we can help you.

Fantastic! This is exactly what I have been looking for! It automatically shows the name of the caller like a land line caller ID. It says "scam" whenever it's a # associated with a scam. It keeps a call history log too! The ads are not intrusive at all for the free version
