Block spam calls by pattern, not just by number. Wildcards, prefixes, and rules — screened silently by Android before your phone ever rings.
Grab the latest signed APK from the Releases page. Requires Android 10 (API 29) or newer, and Globber set as the device's call-screening app.
Most blockers want an exact number. Spam doesn't work that way — it rotates through ranges, spoofs prefixes, and burns a new line every call. Globber blocks the shape of the number.
The name comes from glob patterns: you describe the numbers you want gone, and Globber screens every incoming call against your rules.
+1 800 555 **** → block the whole 555 block
1900* → kill premium-rate prefixes
*0000 → drop sequential robo-dialers
- Pattern rules — match by exact, starts-with, contains, ends-with, or regex; not just exact blacklists.
- Silent screening — uses Android's
CallScreeningService; blocked calls are rejected before they ring. - Contacts-aware — optionally let known contacts through regardless of rules.
- Block log — review every screened call, with day grouping, action filters and search.
- Theming — system / light / dark, with a neon-lime bento UI and custom icon set.
- Backup — export and import your rules as a JSON file.
- Fully private — runs 100% on-device. No
INTERNETpermission, no analytics, no ads. Globber cannot phone home.
