Family Sharing included. • NEW — Block from a screenshot: share a screenshot of your Recents or a spam text to Smart Call Blocker and it reads the numbers on-device (100% offline) so you can block them in a couple of taps. • NEW — Block similar numbers: type or paste a full number and block 1,000 / 10,000 / 1,000,000 lookalikes in one tap, and optionally add neighboring ranges too. • Your saved patterns are always kept — if you're on Free and restore a larger backup, everything stays safe and reactivates the moment you upgrade. • Reliability: sharper screenshot handling, smoother restore, and honest number counts before you confirm a large block. Still 100% offline. Still no data collected. 176 templates · 213 countries. ### 1.0.8 — 2026-07-18 Your patterns now fight spam texts too. • NEW — SMS Spam Filter: the same patterns that block calls now filter spam text messages from unknown senders. Enable it in Settings > Apps > Messages > Unknown & Spam. Filtered texts go to the Junk tab — nothing is ever deleted. Works 100% offline. • NEW — Duplicate Pattern Cleanup: the app spots patterns already covered by a broader rule (when adding, importing, or after iCloud sync on multiple devices) and offers a one-tap review sheet to tidy them up. • Fixed: patterns added from the Templates tab now activate immediately — previously they could stay inactive until your next change. • Clearer feedback: after saving, the app now tells you when iOS has finished loading your block list — and explains the short delay the first time. • Better guidance: patterns that exceed iOS's 1-million-number limit now get a concrete narrower suggestion instead of a bare error. Still 100% offline blocking. 176 templates · 213 countries. ### 1.0.7 — 2026-05-13 iCloud sync, done right — plus a few tools to prove it's working. • Restore from iCloud: preview the patterns saved in your iCloud backup and merge them back to this device. Perfect after reinstalling the app or switching iPhones. • Force Upload to iCloud: a new button in Settings re-uploads all your patterns and shows live sync status, so you can confirm your backup is up to date. • Fixed: older patterns — and the Restore screen — couldn't see your iCloud backup. Sync now reads from the correct iCloud database. • Smarter first launch: a fresh install that finds an existing iCloud backup now offers to restore it automatically. • Clearer sync diagnostics: iCloud setup problems surface as a readable message instead of silently falling back to local-only storage. Still 100% offline blocking. 176 templates · 213 countries. ### 1.0.6 — 2026-05-12 What's new in 1.0.6: • Restore from iCloud — Preview the patterns saved in your iCloud backup and merge them back to this device. Perfect after reinstalling the app or switching iPhones. • Smarter first-launch — Fresh installs that find an existing iCloud backup now offer to restore it automatically. • Sync diagnostics — Setup errors are now surfaced instead of silently falling back to local-only storage. ### 1.0.5 — 2026-05-11 A friendlier upper-limit experience, a faster redeem-code flow, and a wider net of translations. • Removed the self-imposed 10M cap on the blocklist. iOS itself caps Call Directory extensions by device memory, not by a fixed number — Premium users can now push as far as their device allows. • If iOS does reject a save for being too large, the new alert names two concrete rules you can delete (your most recent rule and your largest rule) and removes them in one tap, then re-saves automatically. • Fixed: redeeming a promo or offer code now flips your account to Premium immediately. Previously the paywall could close before Apple finished posting the transaction, leaving you on the upgrade screen for several seconds. • Localization: 192 missing translations filled in across all 8 supported languages (German, Spanish, French, Japanese, Korean, Thai, Simplified Chinese, Traditional Chinese), and Chinese / Japanese punctuation cleaned up. Still 100% offline. 176 templates · 213 countries. ## Related topics [v call filter](https://appshunter.io/ios/topics/v-call-filter) --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
