Call Insider vs RealCall

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.

RealCall is a mobile app for caller ID and spam-call blocking on Android and iOS. It uses a database and AI-based modeling to identify spam and scam calls, and says it can block them before the phone rings. The app also offers reverse phone lookup, with listings of active robocallers and recordings. For texts, RealCall says GPT-4 detects and blocks fraudulent SMS messages. Its AI can also answer unwanted calls to occupy scammers, while user activity helps its system learn spammers’ calling patterns. Blocking settings are customizable, but AI Blocking requires a subscription. RealCall offers a free plan and advertises a free trial; its Subscription is billed Free for 7 days, then $4.49/Month after the free trial. The privacy policy says the app may collect call and text logs, contacts, voicemail recordings, and de-identified texts from callers outside a user’s contacts. Family Plan sharing is temporarily available on iOS only.
