Numbra: Block Spam Calls

Block a thousand spam numbers with one pattern. Put an X where the digits change - Numbra covers the whole shape at once.

Numbra blocks spam calls by pattern, not one number at a time.

Spam callers do not reuse numbers. They burn through thousands that all look alike, so blocking them one by one is a game you lose. Numbra blocks the whole shape at once.

Write the pattern the way you would describe it out loud, and put an X wherever the digits change: +39 12 345X XXXX X. Every X multiplies the reach by ten, and Numbra shows you exactly how many numbers a pattern covers before you save it.

• One pattern can cover millions of numbers • Any country. Pick the dialling code and write the shape • Your contacts always ring. The allowlist beats every pattern • Blocked calls still appear in Recents as missed, so you never lose the record • The blocking runs on your iPhone. Numbra never sees who calls you

HOW IT WORKS

iOS blocks calls through Call Directory extensions, and each one holds a fixed list of numbers. Numbra fills a hundred of them, up to two hundred million numbers, and keeps them in step as you add and edit patterns. You switch them on once in Settings and stop thinking about them.

FREE AND PREMIUM

The free plan runs up to three patterns, each covering up to a hundred numbers. Premium lifts both limits: as many patterns as you like, at full size, up to two hundred million numbers in total.

Every install starts with seven days of Premium. No card, no account.

Premium is an auto-renewing subscription, offered monthly or yearly. Payment is charged to your Apple Account at confirmation of purchase. It renews automatically unless cancelled at least 24 hours before the end of the current period, and you can manage or cancel it in your Apple Account settings.
