Scudo Chiamate blocks unwanted calls and spam SMS on iPhone using iOS's native blocking system.
AUTOMATIC RANGES FROM YOUR NUMBERS — THE KEY FEATURE
The real strength of Scudo Chiamate: the app analyzes the numbers you already have and automatically extracts the ranges that group them. Instead of blocking numbers one by one, you block entire intervals with a single tap — including every variant the same call center will use by changing the last digits.
- Automatic extraction: Scudo scans the numbers in your database and suggests the ranges that contain them. One tap blocks not just those numbers, but all similar ones too
- Manual ranges: define an interval yourself (e.g. from 06.7700.0000 to 06.7700.9999) and cover thousands of numbers in seconds
- Built-in whitelist: keep individual numbers unblocked inside a blocked range
- Clear overview: see how many real and virtual numbers each range covers
Ideal against aggressive telemarketing, organized phone scams and mass advertising SMS, where operators change the final digit on every call.

Ratings & Reviews
This app hasn’t received enough ratings or reviews to display an overview.
iCloud sync
• The sync transition is complete: the app fully leaves the old "snapshot" mechanism behind and syncs only the action history, which each device re-projects to rebuild the same lists.
• Much more reliable across devices: a broad overhaul of the sync engine makes aligning lists and history more robust and consistent — even with multiple devices, reconnections, iCloud account changes, or app reinstalls.
Subscription & purchases
• Improved purchase and restore: "Restore Purchases" works correctly from the purchase screen, and the outcome is shown honestly (completed, cancelled, or pending). Cancelling doesn't close the screen, and an indicator appears while it's being verified.
• Correct handling of purchases awaiting approval (e.g. "Ask to Buy").
Free version
• Active numbers chosen by date: in the free version the numbers applied to iOS blocking are now selected by date, in chronological order, in a more predictable and stable way.
Fixes
• A cancelled or failed import is no longer shown as completed successfully.
• Further fixes for rare crashes at launch and in the background, with better protection while the app is being suspended.
