REPORTS YOU CAN TRUST

After every check, Phone Checker generates a clean, shareable diagnostic report — a phone score along with pass/warn/fail results for every test. Export it as a PDF report to send to a buyer, seller, repair shop, or keep for your own records. Great for anyone who resells phones, runs a repair shop, or just wants proof of a device's real condition.

BUILT FOR EVERYONE

Phone Checker supports 11 languages — English, Hindi, Spanish, Arabic, French, Bengali, Portuguese, Urdu, Telugu, Tamil, and Marathi — with full in-app translation, not just menus. Choose your language once and the entire app adapts, including right-to-left layout support for Arabic and Urdu.

The app also includes both light mode and dark mode, so you can test comfortably day or night, and a clean, modern interface designed to make even technical hardware tests easy to understand for non-technical users.
