Description
Tired of spam calls from the same area codes? Take control of your phone again. Spam Fortress lets you block hundreds of unwanted numbers at once by targeting their area code - no need to block them one by one. Your contacts always get through, and blocked calls go straight to voicemail.

How It Works
Add spam-heavy area codes to your block list (like 800, 888, 877, 866, 855, 844, 833), and the app automatically screens all incoming calls. Contacts are never blocked. Voicemail and text messaging work normally - you'll never miss emergencies.

Key Features
Smart Blocking:

Block by area code - Stop hundreds of spam numbers instantly
Multiple blocking modes - Block specific codes OR allow only trusted codes
Contact protection - Your saved contacts always get through
Individual number blocking - Block specific numbers too

Call Management:

Detailed block history - See every blocked call with timestamps
Customizable notifications - Control when you see block alerts
Scheduled blocking (Pro) - Auto-enable blocking during work hours
Quick Add spam codes (Pro) - Add common spam area codes with one tap

Pro Features:
