In their own words
Call Insider
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.
Whoscall
Whoscall identifies incoming callers in real time and blocks spam and scam calls on Android and iOS. Its AI checks phone numbers, links, and screenshots against trusted data to flag possible risks. The app also offers Scam SOS, with one-tap access to bank hotlines and online scam reports, and Voice Alerts that warn about suspected scam calls; both features vary by region. Users can report scams and earn points and badges, contributing information to the community. Whoscall says its number database holds more than 2.6 billion entries. The free plan includes caller ID, call blocking, checks for numbers, links, and screenshots, and scam reports and rewards. Paid Individual, Duo, and Family plans add account sharing, database updates, an SMS assistant, ad-free use, and automatic spam blocking; Live Caller ID Plus is limited to iOS 18 or later. Individual costs $27 a year. Business customers can apply for Verified Business Number, which displays a verified company name and logo and requires a minimum six-month purchase.
