Offline phone-number lookup and WhatsApp launcher—privacy-safe.
Number Checker — description
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.
