RealCall vs RoboKiller

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.

RoboKiller is an Android and iOS app that blocks spam calls and filters spam texts. Its call-blocking algorithm analyzes call metadata in less than a millisecond and blocks calls it identifies as spam before they reach the phone. Audio fingerprinting compares robocall recordings against a database of more than 1.5 billion processed phone numbers and millions of audio fingerprints. RoboKiller says its technology is 99% effective at stopping spam calls. Text filtering uses block and allow lists, number reputation, and content analysis; the company says messages are never stored or shared. The free version includes a daily-updated blacklist, blocked-call notifications, weekly insights, spam reporting, and Spam Patrol. Answer Bots, Call Screening, and Personal Data Protection require a paid plan. Answer Bots play prerecorded messages to spam callers, while Call Screening asks unknown callers for their name and reason for calling. Both features require a carrier and plan that support Conditional Call Forwarding. Listed paid options include $4.99 a month, $31.99 a year, and $39.99 a year; a 7-day trial is also listed.
