An advanced SMS blocker for Android 4.4+ (requires Xposed framework)
NekoSMS is a simple yet powerful SMS blocker that complements your favorite SMS app instead of replacing it. Want to block messages containing specific keywords, but don't want to change your default SMS app? NekoSMS can help! NOTE: Requires Xposed framework.
Features
• Block SMS messages based on their sender, content, or both
• Supports regular expressions, wildcards, whitelisting, and more
• Share filter rules across devices using the import/export feature
• No telemetry, no ads, no internet permissions
• Free (both as in beer and in speech)
Usage
NekoSMS does not come with any built-in spam filters -- you write the rules yourself! Here's a few examples of what you can do:
• Block messages containing "cat facts"
• Block messages coming from numbers starting with "100"
• Block messages coming from "12345" ending with "unsubscribe"
