Hey Product Hunt 👋 I get spam calls every day. They never come from the same number twice — the same scam burns through +1 800 555 0101, 0102, 0103… and my carrier's blocklist adds them one at a time, always behind. So I thought: why am I blocking numbers when I could block the shape? One rule — 1900* — kills the whole prefix. *0000 drops every sequential robo-dialer. Regex for the rest. Globber is a free, open-source Android app built on the system CallScreeningService: • Five match types — exact, starts-with, contains, ends-with, regex • Screened before it rings — Android hands the caller ID to Globber, not the other way around • Reject, silence, or voicemail — pick the action per rule • Block log — every screened call, grouped by day, searchable • JSON backup — export and import your rules It has no INTERNET permission. Literally can't phone home. No analytics, no ads, no accounts. Everything stays on your device. Grab the signed APK from GitHub Releases. Android 10+. I'd love to hear what patterns you'd write first!
