How it works

Stops spam at the
OS level

No VPN No battery drain Native iOS blocking

Sync the blocklist

Hush downloads the latest spam database, updated daily from the FTC, community reports, and open source lists.

Stored on your device

The blocklist lives entirely on your iPhone. When a call comes in, no network request is needed. It is instant.

Calls are silently blocked

iOS checks each incoming number against the list. Spam numbers are rejected before your phone ever rings.

Report and improve

See a spam call? Report it in the app. Your anonymous report immediately improves protection for everyone.

Data sources

Powered by real data

Hush aggregates spam intelligence from multiple trusted sources, merged daily into a single blocklist that syncs directly to your device.

FTC Do Not Call Registry

Thousands of daily complaints filed with the US Federal Trade Commission, updated every weekday.

Community Reports

Numbers reported anonymously by Hush users in the app. Three independent reports required before a number is added.

Open Source Blocklists

Curated lists from trusted open source projects containing thousands of verified spam numbers.

Hush Network

Numbers identified and continuously flagged through the Hush platform, synced to your device on every update.

🔒

Your privacy is protected

Hush never accesses your call history or contacts. Blocking runs entirely on device via iOS CallKit. When you report a number, only the number and spam category are sent. Never your identity.
