Add-free Robingarde CallBlock blocks unwanted calls automatically — before your phone ever rings. It works as a native Android Call Screening service, so unwanted callers are rejected silently in the background.

🛡️ SMART CALL SCREENING
Answer a call? Not anymore. CallBlock screens every incoming call and decides in an instant: ring, reject, or silence. Unwanted callers and numbers you've blacklisted never interrupt you again.

🚫 FOUR FILTER MODES
• Block Blacklist (default) — block only the numbers you choose
• Contacts Only — allow calls from your contacts, block the rest
• Favorites Only — even stricter: only favorite contacts get through
• Filter Disabled — screen nothing, decide manually

📇 WHITELIST & BLACKLIST RULES
Build your own block lists. Add numbers by hand or straight from your screening history. Use exact numbers or wildcards (e.g. +1800*) to catch whole number ranges — from one spoofed call center or an entire country prefix.

🔐 STIR/SHAKEN SPOOF PROTECTION
On Android 11+, CallBlock reads the carrier's caller ID verification status and can automatically reject calls with failed verification — the hallmark of spoofed, faked caller IDs.

🔕 YOUR CHOICE OF BLOCK ACTION
Rejected callers get a busy tone, or a silent ring — you decide. Blocked-call notifications can be turned off entirely for truly invisible blocking.

📋 LOCAL BLOCK HISTORY
Every screened call is logged with the reason it was blocked or allowed, the caller's name, and its STIR/SHAKEN verification status. Grouped by number, searchable, with a configurable retention period (7, 30, 90 days, newest 1,000 calls, or forever).

🔒 YOUR DATA NEVER LEAVES YOUR PHONE
CallBlock has no ads, no analytics, no accounts and no internet access. All rules, logs and settings live in a private database on your device only. Deleting the app deletes everything — nothing is ever uploaded or shared.

🌍 AVAILABLE IN 13 LANGUAGES
English, Slovenčina, Čeština, Magyar, Polski, Deutsch, Italiano, Français, Español, Português, Nederlands, Svenska, Norsk.

✨ FULLY OFFLINE
No cloud, no accounts, no subscriptions. Everything works in airplane mode.

Robingarde CallBlock uses the official Android Call Screening API. It never uploads, shares or sells your contacts, screening log or any personal data — everything is processed locally on your device.

Take back your peace and quiet. Install Robingarde CallBlock and let the spammers ring a phone that never rings for them.
