CallDam vs Ringfold

CallDam is built for mass call blocking by phone-number prefix. Instead of blocking one unwanted number at a time, CallDam lets you create prefix rules that can protect thousands of related numbers at once. The app is designed for large blocking lists, with support for up to 1.8 million active protected numbers. A key feature is direct blocking from the iPhone share flow. When you see an unwanted number or contact, share it to CallDam and create a prefix blocking rule without manually opening the app and rebuilding the rule step by step. Main features: • Block unwanted calls by phone-number prefix • Protect large ranges of related numbers • Support for up to 1.8 million active protected numbers • Add exact-number exceptions for numbers you still want to allow • Pause, resume, edit, or delete rules • Batch-edit multiple rules before applying changes • Add rules directly from the iPhone share sheet • Import and export local JSON backups • Apply your active block list through iOS Call Blocking & Identification Private by design: • No account required • No ads • No subscriptions • No in-app purchases • No tracking • No contact access required • No blocked-number uploads • Your blocking rules stay on your device CallDam prepares your active blocking list locally and applies it through Apple’s iOS Call Blocking & Identification system. Supported prefix-blocking countries and regions: Russia / Kazakhstan (+7), USA / Canada (+1), Armenia (+374), Belarus (+375), Ukraine (+380), Tajikistan (+992), Azerbaijan (+994), Georgia (+995), Kyrgyzstan (+996), Uzbekistan (+998), France (+33), Spain (+34), Poland (+48), Denmark (+45), Norway (+47), Netherlands (+31), Switzerland (+41), India (+91), Iran (+98), Australia (+61), Singapore (+65), Turkey (+90), South Africa (+27), UAE (+971), Saudi Arabia (+966), and Egypt (+20). Important: To block calls, you must enable CallDam manually in iOS Settings: Settings > Apps > Phone > Call Blocking & Identification. CallDam does not collect, upload, sell, or share your blocked numbers.

The last digits change. Block similar phone numbers with one rule. Ringfold helps you choose which calls to block on your iPhone. Start from a number, compare two numbers, or review numbers detected in a screenshot. PREVIEW BEFORE YOU BLOCK Block one exact number or a supported range with the same prefix and changing final digits. Compare two numbers to find the smallest supported shared pattern. See the first and last number and the count of possible numbers before saving. Templates help you choose a starting range. SCREENSHOTS AND NUMBER LISTS Choose a screenshot and review the phone numbers recognized on your device. With Pro, add selected exact numbers to a new or existing number list, even when they do not share a prefix. Lists contain the selected numbers, not the gaps between them. A single selected number can also open the rule editor: check its range before saving. Ringfold does not read your call history automatically. EXCEPTIONS, CHECKER AND CALLER LABELS Keep specific numbers as exceptions to Ringfold rules. Check a number against your saved rules. Your rule names provide caller labels where iOS displays identification; they are your labels, not a spam reputation lookup. AUTOMATIC UPDATES AFTER ACTIVATION Enable Ringfold in iPhone Call Blocking & Identification settings. After activation, saved rules, pauses, deletions, exceptions and confirmed imports update iOS automatically while the app runs. Check the update status; failed updates need attention. KEEP YOUR RULES Choose the number country independently of your iPhone region. Export rules and exceptions to Files. Preview a backup import before adding it; existing rules stay unchanged and duplicates are skipped. Undo the last deletion during your session. START FREE, ADD MORE WITH PRO One ordinary rule for an exact number or range is free. Pro unlocks multiple rules and number lists with a monthly or yearly subscription. Current prices and any available free trial offers are shown before purchase. Subscriptions renew automatically unless cancelled. Payment is charged to your Apple Account.

Blocking works offline after setup and a successful update. Usage analytics excludes phone numbers and rule names. A range can include wanted callers. Counts mean possible numbers, not calls stopped. Exceptions apply only to Ringfold. iOS, contacts, recently dialled numbers, other identification services and your carrier can affect blocking, labels and voicemail. Ringfold does not automatically detect every spam caller. Privacy Policy: https://katenin.dev/ringfold/privacy Terms and Conditions: https://katenin.dev/ringfold/terms
