AI call blocker
for iPhone.
Spam numbers keep changing. Block a pattern they share.
Import a screen recording of your recent calls. CallBlocker uses on-device AI to suggest number patterns. You review each suggestion, then iOS blocks calls that match your approved rules.
Requires iOS 26 or later. Recording import and AI suggestions also need Apple Intelligence; blocking works without it.

Setup
From recent calls to block rules.
- Enable CallBlocker in iPhone Settings.
- Record visible numbers in your recent calls.
- Import the video in the AI tab.
- Review suggested patterns before blocking.
The app reads numbers from the recording you select. It cannot browse your Phone app history automatically. Suggestions depend on the history you have imported; you may need more history before a pattern appears.
- Choose what to block. Accept or dismiss AI suggestions. Add individual numbers or your own wildcard rules.
- Keep your rules under review. Import new recordings as unwanted calls change. A number outside your active rules can still get through.
- Review the whole range. A wildcard can include legitimate numbers. Similar digits alone do not prove a caller is spam.
Blocking
iOS blocks numbers that match.
Once your rules are loaded and the extension is enabled, iPhone checks incoming numbers against the block list through Apple's Call Directory system. CallBlocker does not answer calls or listen to conversations.
Blocking a number does not guarantee an empty voicemail inbox. CallBlocker does not control your carrier's voicemail routing. Understand blocking and voicemail.
Fewer interruptions.
Suggestions
A suggested pattern. A reason to review.
CallBlocker uses Apple's on-device Foundation Models to look for groups of numbers in your imported history. Each suggestion includes a short explanation in English. You decide whether the proposed range belongs on your block list.
Recording analysis and AI processing run on your iPhone. Block rules can sync through your private iCloud database when available. Read how your data is handled.
Illustrative patternReview the range
Each * replaces one digit. Two wildcards cover 100 possible numbers, from +1 202 555 0100 to +1 202 555 0199.
This demonstrates the rule syntax. It is not an actual AI result or a list of known spam callers.

Questions
Before you use CallBlocker.
Will it stop every spam call?
No. CallBlocker blocks numbers that match active rules loaded into iOS. A caller using a different number outside those rules can still reach you. AI suggestions can also be wrong, so review the range before approving a rule.
Does CallBlocker automatically read my call history?
No. You select a screen recording to import. CallBlocker extracts visible phone numbers from that recording on your iPhone. It does not have automatic access to the Phone app's recent calls.
Is this the same as iPhone's call screening?
No. Apple's call screening can ask an unknown caller why they are calling. CallBlocker suggests number patterns for a block list you control. It does not speak to callers. Compare the options.
Can it block No Caller ID calls or text messages?
CallBlocker's rules need a phone number to match. They do not provide a blanket block for hidden caller IDs. This app is for phone calls; it does not filter SMS, WhatsApp or FaceTime calls.
Can a broad pattern block someone I want to hear from?
Yes. A pattern covers every number it expands to, so it can include legitimate callers. Use a narrow range you understand, review it before enabling it, and remove or disable a rule if it causes problems.
Does all of my data stay on my iPhone?
Recording analysis and AI run on-device. Block patterns, labels and rule settings can sync through Apple's private iCloud database when available. Your Photos and device backup settings may also store data with Apple. Read the privacy details.
