Detect unknown calls while the phone is ringing, block unwanted calls, reverse search for phone numbers, and rate callers: All of this is offered by the tellows App!

- Free identification of incoming calls
- Detection of spam calls, ping calls, advertising calls, telephone terror
- Block calls (call blocker) and receive personalized blacklist with tellows Harassment Protection Pro
- Reverse search of telephone numbers
- Submit ratings and comments on phone numbers
- Login for the tellows member area

When you receive a call from a phone number previously reported on tellows, the tellows score will be displayed while the phone rings. This score shows how the number was rated by the community (1 very trustworthy - 9 dubious). Harassment Protection Pro also displays the caller type (e.g., Sweepstakes) and caller name. With the Share Contact feature, you can easily search for information on this phone number in the app from your iPhone calling list. Here you can find details about the phone number and all ratings by tellows users. In the app, phone numbers can be searched and rated, so you can easily become part of the community. The login to the tellows member area allows you to edit your ratings and use them across devices. Your submitted comments will then be assigned to your user account and negatively rated numbers will be added directly to your personal blacklist (attention: blacklist is only available with Harassment Protection Pro).

Harassment Protection Pro displays the most important phone number details available during ringing: score, caller type, and caller name, for example: (8) Sweepstakes, Lottery24.
In addition, calls are not only identified but can also be blocked. Determine from which tellows score numbers should be blocked. All phone numbers reported by tellows users with the selected negative score are automatically blocked. The blacklist contains only currently relevant phone numbers that have been classified as disruptive by the community. With the tellows login we also offer you a personalized blocked list.

The tellows harassment protection includes a one-year subscription. Payment will be charged to the iTunes Account at confirmation of purchase. Account will be charged for renewal within 24-hours prior to the end of the current period, and calculate the cost of the renewal. The subscription automatically renews unless auto-renew is turned off at least 24 hours before the end of the current period. Subscriptions can be managed and auto-renewal turned off in Account Settings in iTunes after purchase

tellows is an open forum for phone numbers, based on the comments and experiences of all tellows users, giving you access to more information than a regular telephone directory. Currently, the tellows consumer protection service at www.tellows.co.uk is used by more than 7 million users per month all over the world, sharing their experience regarding unknown or dubious phone numbers.

- Over 300,000 tellows users rate more than 1,000 phone numbers every day
- Access over 1 million details about phone numbers collected by the community
- tellows has been active since 2010 in more than 50 countries

Since tellows is no official telephone directory, and since it is not our aim to provide data about private numbers, we are unable to provide information regarding all existing phone numbers. Our goal is rather to provide useful information about general unknown or suspicious numbers of public interest. The data brought to you is based on the complete and undelayed information provided by the rest of our community.
