## What is Call Shield?

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.

iCLOUD SYNC
- Blocked numbers, allowed numbers and ranges sync automatically across all your devices via iCloud
- Add a number on one iPhone and find it on the others within seconds
- Data stays in your private iCloud container: only you can access it, no third-party server

ACTIVITY & HISTORY
- New "Activity" tab: a history of every change to your lists (additions, imports, deletions, applied ranges)
- Undo and redo operations with a tap, with confirmation of the affected numbers
- History statistics and customizable appearance

CALL BLOCKING
- Single numbers or entire prefixes
- OCR recognition from camera or screenshots
- Import contacts from your address book
- Add numbers from any app via the Share extension
- Import/export CSV

MESSAGE FILTER (SMS)
- Native iOS filter: moves unwanted SMS to the dedicated folder
- No access to message content

PRIVACY
- Numbers stay only on your device and in your private iCloud
- No tracking, no ads

FREE UP TO 500 NUMBERS
Premium unlocks up to 500,000 numbers applied to iOS blocking, automatic range management, full CSV export, and filters with action undo.

Perfect for anyone tired of telemarketing, phone scams and unwanted commercial SMS.

## Version history (last 5 releases)

### 1.4 — 2026-07-28

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.

### 1.3.5 — 2026-07-11

Interface
• Redesigned confirmations: the confirmation prompts for deleting, moving (Block/Unblock) and exporting now use panels consistent with the rest of the app, instead of system alerts.
• Clearer actions in the lists: in the action bar "Unblock" is green and "Block" is orange, and the icon reflects the destination list.
• Greater visual consistency throughout the app: unified status colors and panel styling.

Export & maintenance
• Simplified Allowed export: a direct two-option confirmation, with no range selector (the Allowed list has none); the panel shows what's included or excluded.
• The cleanup overlay distinguishes Cache and Database more clearly.

Activity
• The Restore and Redo swipe icons are larger and easier to read.

Analysis
• Range deletion with clear feedback: during the operation a panel shows the status in place — in progress, done, or a warning if something goes wrong — with a final confirmation.
• Animated transition of the found and discarded range cards when you apply the results.

Fixes
• Import from images (OCR): foreign numbers written with spaces are now recognized and imported correctly.
• Fixed an "Apply" bar that could appear in the Analyze tab with no actual changes to apply.
• The iCloud sync status now correctly shows the date of the last send and the last receive.
• Further fix for a rare crash at app launch when the device was locked.

### 1.3 — 2026-06-24

ACTIVITY & HISTORY
• New "Activity" tab: a history of changes to your lists — additions, imports, deletions and applied ranges.
• Undo and redo actions, with a confirmation showing the affected numbers.
• New "Appearance" tool to customize the colors and size of the history icons.
• History statistics with a breakdown by type of change.

iCLOUD SYNC
• Redesigned sync: lists and history stay aligned across your devices and, on activation, data is merged automatically.
• No more device/iCloud choice prompt when one side is empty.

IMPORT & EXPORT
• Redesigned import and export screens — clearer and smoother.
• Progress bar during import, now cancelable and with a more accurate percentage.
• Fixed: a button hidden at large text sizes in "Import from images", and invisible characters in numbers pasted from messages.

ANALYSIS
• New range row layout: an index chip, the interval highlighted and a visual connector.
• More accurate and faster analysis on large databases; better handling when the database limit is reached.
• A clear message when the database can't be read.

LISTS & BLOCKING
• The list refreshes when you return to the app after changes made by other extensions.
• Full-screen confirmation with an animated checkmark after adding a number.
• A button to retry the iOS blocking update when the last operation failed.

SETTINGS & PREMIUM
• Refreshed Premium: a new intro card and a redesigned purchase screen; the unlock beyond 500 numbers is highlighted.
• With Premium, list/activity filters and undo are enabled automatically.
• Database space now distinguishes Numbers, History and Other.

INTERFACE & ACCESSIBILITY
• Removed the "Extension active" notice shown at launch.
• Better scrolling at large text sizes (Dynamic Type).
• The "What's New" row shows the version in use.

STABILITY & PERFORMANCE
• Fixed a rare crash at launch when the device was locked.
• Greater stability and reliability in database and iOS-blocking handling, even with very large lists.

### 1.2 — 2026-06-05

• UI improvements and the fix of an annoying bug that could cause the app to crash in the background.
• Refactored the CallKit reload with a new technique, which made it possible to raise the database limit to 500,000 numbers — double the previous version. Measurements show no issues even on older devices.
• Free-version limit raised to 500 numbers active in iOS blocking.
• Completely reworked the logic for discarded ranges. It moved from a fixed-threshold criterion (ranges over 500 numbers with fewer than 15 origins) to a density-based one: a range is discarded when its Origin numbers don't reach at least 0.65% of the covered numbers (examples in the online guide).
• Added the option to import contacts from your address book. The range of import methods is now truly complete.
• Added number recovery from screenshots (OCR). Re-importing the iOS blocked list is now quick and easy, with a step-by-step guide explaining how.
• Added a comprehensive online guide for clarifications on every feature of the app.
• New "Links" section in Settings gathering the user guide, what's new, privacy policy, and support contact.
• Reworked the Analyze section to make the explanation of the search parameters clearly visible, now unified with the ranges explanation; the info has its own dedicated button.
• Reworked the Allowed list. Since it has no range logic, the filters and the legend in its popup — previously identical to the Blocked one — were adjusted.
