## What is Chanso?

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.
