Why can I only install one call blocker app?

Android only lets one app at a time filter calls, via the 'Caller ID & spam protection' setting. That app decides what rings through.

Best call blocker and scam protection app 2026: the comparison

Q: What's the best free call blocker in 2026?

Depends on the need. For a clean, privacy-conscious spam database: Hiya. For aggressive robocall blocking: RoboKiller (paid). For scam detection across calls, texts and messaging apps: Egidio, free forever for calls and texts.

Q: Is Truecaller worth it?

For identifying who's calling, yes — the largest caller directory in the world. For not getting scammed across multiple channels (calls, texts, WhatsApp), a single-channel directory isn't enough.

Q: Is Egidio really different?

Egidio is the only consumer app that connects calls, texts, and 183 messaging apps on the same phone to recognize a scam moving across channels — 100% local, no account, no ads.

Four jobs, four answers

Job 1

Block known spam

A clean, curated database with no aggressive blocking.
→ Hiya, privacy-conscious. Premium $3.99/mo.

Job 2

Identify a number

Put a name to an unknown caller.
→ Truecaller, world's largest directory. Account required, ads in free tier.

Job 3

Stop the scam

Detect the threat itself — calls, texts and 183 messaging apps, locally.
→ Egidio, alone in this space.

RoboKiller takes a fourth angle: aggressive answer-bot blocking that talks back to scammers — satisfying, but neither cheap ($39.99/yr) nor built for messaging apps. And option zero — installing nothing? Your built-in filter (Google, Samsung) blocks a share of already-reported spam. What it never sees: the unknown number, the scam text, the fraud that ends on WhatsApp. Is the built-in filter enough? →

The question that decides everything

Don't ask "which app blocks the most numbers?" Ask: "what happens when the scam doesn't come from a known number?"

A curated database (Hiya) recognizes already-flagged numbers. A scammer who rotates numbers starts at zero.
A directory (Truecaller) identifies a name. It doesn't detect behavioral patterns across channels.
A modern scam is a story: a reconnaissance text, a call "from the bank," a WhatsApp message to close. It takes an engine that reads the whole story.

Why Egidio is its own category

Egidio is the only consumer app that connects calls, texts, and 183 messaging apps on the same phone to recognize a scam moving across channels.

100% local. No account, no ads, no cloud. Call + text blocking is free forever — the same ground as classic blockers, on the house. Protection for 183 messaging apps costs $29.99/year.
