Handy Features For Everyone

We've designed the app to do exactly what you need. And nothing more.

Identification of callers

More then 10 million of identified telephone numbers. We use data from more than 70 websites to recognize phone numbers.

Call blocker

No more unsolicited calls. You can block certain numbers as well as all hidden or unknown numbers.


Number rating

By rating numbers, you help both the other users and yourself. Moreover, you harm telemarketing companies. Yay!

Privacy protection

Protecting your privacy is our No. 1 priority. We only use your contacts to distinguish the known numbers from the unknown. We never save them and don’t give them to anyone.

Frequently Asked Questions

When is the iPhone app going to be available?
We are currently hard at work developing the iOS app. We suppose we will release it in the first half of 2018. Just like the Android version, the iOS version will be completely free and without ads.
Why does the app need access to my contacts?
We want the app to display only unknown phone numbers. We also want to show comments on a phone number only when an incoming call is from a number not saved in your contacts. That is the only reason we require access to your contacts. We never save them or send them anywhere. Your contacts never leave your phone.
Why does the app need access to my texts?
The app lets you see information not only on the phone numbers that have called you, but also on numbers that have sent you a text message. We, therefore, need access to your texts. We are, however, only interested in the sender, not the content. We understand that not everybody will use this feature, so we are planning to make the permission to access texts optional. If you do not grant it, you will not be able to use this feature.
