They change numbers.
You block the pattern.

Choose the starting digits to cover similar numbers, even when the last digits change. You enter any country code yourself. Goyo uses Apple’s native iOS call-blocking system to apply supported rules; broad ranges can exceed its capacity.

Saving a rule is the first step. It becomes active only after iOS confirms that the blocking list was imported successfully.

Unknown numbers outside your chosen blocks may ring. Goyo does not treat every new caller as spam. A delivery driver or bank can share the same starting digits as a blocked group, so your choices can include legitimate callers too.

Add an important number to Always allow to exclude it from Goyo’s blocks. Other iPhone settings, carrier services and blocking apps still apply.

On eligible devices, optional AI assistance reviews call notes you type. It does not listen to calls, identify incoming spam automatically or block a caller based on its review. When AI is unavailable, a basic local check is clearly labeled.

Automatic reputation-based detection is not connected. If a spammer switches to a number outside your chosen rules, that call can still get through.

Support for large groups of similar numbers is limited and still in development. A full Korean 070 range failed our iPhone test and is not supported. Smaller lists also need a successful iOS import before they take effect.

Shared starting digits are a filtering choice, not proof of spam. Goyo cannot guarantee that it will stop every caller who changes their number.

Goyo is in development and is not available on the App Store. The examples on this website illustrate how the app works; they do not detect real callers or change your phone’s settings.
