Number Checker

1. Number Checker is a privacy-first analyzer for international phone numbers.

2. Parse any number offline to detect the country/region, format it (E.164, RFC3966, national, international), and validate length/structure instantly.
Identify carrier type and operator name, surface currency/locale hints, and paste or type numbers with auto-format examples.

3. Trigger WhatsApp chats directly from parsed results.

4. Powered entirely by on-device —no accounts, no ads, no network connection needed—so your inputs never leave the phone.
