CallShield shows you who's calling and stops unwanted calls before they ring. It's a caller ID app, a spam call blocker and a complete phone app.

🛡️ BLOCK SPAM CALLS AUTOMATICALLY
Choose which calls to block, and CallShield rejects them silently:
• Numbers commonly reported as spam, scam or telemarketing
• Numbers on your personal block list
• Hidden or private numbers
• Callers who aren't in your contacts
• International calls from outside your country
Blocked calls stay in your call history, so you never lose track of who tried to reach you.

📞 KNOW WHO'S CALLING
• Full-screen caller ID with name, location, carrier and line type
• Clear red warnings for suspected spam, with the number of community reports
• Caller details in your call history, so you can tell "Identified", "Spam" and "Scam" at a glance

🚫 YOUR BLOCK LIST, YOUR RULES
Block any number in one tap: type it in, pick it from your call history, or choose a contact. Unblock it just as easily.

🔍 SEARCH ANY NUMBER
Look up an unknown number before you call back and see its location, carrier and spam reports.

🙋 HELP OTHERS AVOID SPAM
Report a number as Spam, Scam or Telemarketing. Every report helps protect the whole community.
