Chanso – Block Nuisance Calls

Chanso blocks nuisance calls by number range, not just one number at a time. Type "0241 234 xxx" and 1,000 numbers with that prefix are blocked at once; the app loads up to 10 million numbers into your iPhone's block list, and those calls never ring. Easy for everyone • Large text, large buttons, one task per screen. • No account, no typing words, digits only. Find nuisance numbers from a screenshot • iPhone doesn't let apps read your call log. Take a screenshot of Recents and Chanso reads the numbers on your phone, then suggests repeat callers and shared prefixes. You just tap Block. • Images are processed on device and never uploaded. Community lists • Download reviewed lists and use them right away. • Share your own list; a moderator reviews it before it goes public. Clear and safe • See how many numbers a pattern covers before blocking, with a warning when a range is too wide. • Unblock with one tap; changes are pushed to iPhone immediately. • Vietnamese and English; 230+ countries. 3-day free trial with every feature, then a one-time purchase. No subscription. Note: Chanso uses iOS Call Blocking & Identification. After installing, turn Chanso on once in Settings → Phone → Call Blocking & Identification. Numbers saved in Contacts may not be blocked; this is an iOS limitation.
