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. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

Verdict
The clearest difference is price: Call Shield at Free against MobileOp's $0.99. Call Shield also leads on update cadence (every 2 weeks vs every 3 months). MobileOp's advantage is in-app purchases (none vs 1) and device support (3 vs 1). On ads there is nothing between them.
