CallGuard – Spam Blocker App-Analysen für 30. Januar

CallGuard is a powerful call blocking app that puts you in control of who can reach you. Using Apple's official Call Directory Extension, CallGuard blocks unwanted calls at the system level — before your phone even rings. USER-DEFINED BLOCKING CallGuard does NOT contain any pre-populated block lists or spam databases. YOU decide which numbers to block by creating your own rules. Numbers are only blocked when you explicitly add them — nothing is blocked automatically. You have complete control over the blocking criteria. KEY FEATURES • Flexible Blocking Rules — Block calls by exact number, number range, or prefix pattern • Visual Range Editor — Fine-tune your blocking ranges with intuitive drag controls • Contact Protection — Automatically whitelist your contacts so they're never blocked • Smart Overlap Detection — See which rules overlap and exactly how many numbers are blocked • Capacity Management — Track your usage against Apple's 100K number limit with visual indicators • Privacy First — All data stays on your device; contacts are processed locally and never uploaded • Multi-Language Support — Available in English, French, German, Spanish, and Chinese HOW IT WORKS CallGuard uses iOS's native Call Directory API to block calls at the system level. Create blocking rules for specific numbers, ranges, or prefixes, and sync them to iOS. When a blocked number calls, iOS silently rejects it before your phone rings. BLOCKING OPTIONS • Exact Number — Block a specific phone number • Range — Block all numbers within a range (e.g., +1 555-100-0000 to +1 555-199-9999) • Prefix — Block all numbers starting with a prefix (e.g., all +1 555-XXX-XXXX numbers) VISUAL RANGE EDITOR Adjust your blocking ranges with precision using our visual editor. Drag handles to expand or shrink ranges, use quick adjustment buttons (+10, +100, +1K), and see real-time feedback on how many numbers will be blocked. PROTECT YOUR CONTACTS Enable contact protection to ensure your saved contacts are never accidentally blocked, even if they fall within a blocking range.
