Call Control vs Call Insider

Call Control has no write-up on Specifiction yet; its figures are above.

Call Insider is a free caller-identification service available on Android and the web. It helps people assess unknown phone numbers by showing ratings during calls or in a pop-up. The mobile app uses a database with more than 300 million identified numbers, drawing data from more than 100 websites. A downloadable database covering more than 100 countries supports lookups without an internet connection. Users can rate numbers, read other users’ ratings, see yearly interest in a number, and sometimes view a landline location. The service is intended for calls such as telemarketing, surveys, courier contacts, and office calls. Free registration provides fewer ads, editable rating history, reply notifications, more daily comments, and easier reporting of harmful comments. Call blocking for potentially harmful and unsaved numbers is described as in development. The service was created in the Czech Republic in 2011.
