## What is Ringfold?

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. Manage or cancel your subscription in the App Store.

Rules and exceptions stay on your iPhone unless you export them. No account, ads or contact uploads. 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.
