Call Insider is a free application which helps to identify unknown phone numbers and block unsolicited calls. We have designed the app to do exactly what you need. And nothing more. That makes using it very easy.

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 any phone numbers you want including hidden, unknown and telemarketing 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.
