Deep Dive Into This App JustBlocked: Spam Call Blocker

*You have the option to set all blocked calls to skip voicemail.
*Designed to give you that feeling of being in control again.

JustBlocked is a privacy-first app, no-nonsense call blocker and full phone dialer that does all of its screening on your device. No ads. No tracking. No internet permission—so nothing can leave your phone. Set it as your Default Phone App to take control of who can ring you, who gets sent away, and when your phone stays quiet.

Why JustBlocked?
• Built for privacy: works 100% offline.
• Effective rules engine: match exact numbers, prefixes, names, and more.
• Simple, reliable UI with zero bloat.

Key Features
Default Dialer Integration: Place and receive calls normally while JustBlocked screens incoming calls in real time.

Smart Blocking Modes
• Blocklist mode – silence known spam/scam numbers you add.
• Contacts-Only – allow calls from people saved in your Contacts; block others.
• Block private/hidden/unknown caller IDs.
• Allowlist – numbers that should always be let through.

Aggressive Answer + Hang Up (optional): Auto-answer a blocked call and disconnect immediately to end robocalls quickly. (No audio recording; no media permissions.)

Powerful Rules
• Exact number, Starts with, Ends with, Contains, and Regex for advanced patterns.
• Handy presets for toll-free, area codes, country codes, etc.
• Number normalization (E.164-style heuristic) so 123-456-7890, +1-123-456-7890, and (123) 456-7890 all match the same rule.

Quiet When Blocked: Optionally skip call-log entries and silence notifications for blocked calls.

In-Call UI: Clean screen with caller name/number, large Answer/End buttons, and a modern keypad overlay.

Safety First: Emergency numbers (e.g., 911/112) are never blocked.

Lightweight: Minimal battery and storage usage. No background network traffic—ever.

Privacy & Security

No accounts, no analytics, no ads, no SDK trackers.

The app does not request INTERNET permission.

Your blocklist/allowlist live only on your device in the app’s private storage. Uninstalling the app or clearing its data removes them.

Permissions Used (Plain English)

READ_PHONE_STATE / ANSWER_PHONE_CALLS – Detect and (optionally) auto-answer/hang up blocked calls.

READ_CONTACTS – Show contact names/photos in the in-call screen and support Contacts-Only mode.

CALL_PHONE – Place calls like a normal dialer.

READ/WRITE_CALL_LOG – Optionally prevent blocked calls from cluttering your call history.

How It Works

Make JustBlocked your Default Phone App (Android will prompt you).

Grant the suggested permissions.

Add numbers or patterns to your Blocklist and Allowlist; or choose Contacts-Only.

(Optional) Enable Aggressive Answer + Hang Up for faster disposal of spam calls.

You’re done—enjoy a quieter phone.

Who It’s For

Anyone tired of spam/robocalls.

Professionals who need a clean, dependable dialer with strict control over who can reach them.

Privacy-minded users who want zero data sharing.

Notes & Tips

Behavior may vary by carrier/OEM. Ensure JustBlocked is the Default Phone App and battery optimization doesn’t restrict it.

You can change modes and rules anytime; your choices apply instantly.

Take back your phone—block the noise, keep the calls that matter.

I've been looking for an app that blocks and hangs up on the caller so they can not leave a voicemail message. This app's Hang Up feature works! It's just a click they hear, and that's exactly what I wanted. The app has a nice layout with all the other features you would want in a comprehensive call blocker. And it's easy to configure. 5 🌟

I never realised i could message through the app itself I will give it another chance just hope it doesn't block my oldest sister again she has to be able to get in touch due to mobility issues. Thank you for responding so fast that says you care about the ones who use your app and that means alot to me will increase rate on that alone.
