## Description

iDiagnostic is a fast, easy-to-use hardware diagnostic tool for iPhone and iPad.

In just a few taps, verify that every key hardware component on your device is working correctly:

DISPLAY
- RGB color test cycles through Red, Green, and Blue full-screen patterns to spot dead pixels and color shifts.

TOUCH SCREEN
- Configurable grid (4x3 to 20x12) covers the entire screen so you can confirm every region responds correctly.
- Real-time progress counter — tap to fill cells, get instant pass/fail when complete.

CAMERAS
- Detects every physical camera on your device — wide, ultra-wide, telephoto, TrueDepth, LiDAR.
- Test each one individually with live preview and capture.

LOUD SPEAKER
- Plays a recognizable melody (Twinkle Twinkle Little Star) through the bottom speaker so you can verify audio output and quality.

INTERNAL SPEAKER (EARPIECE)
- Same melody routed through the top earpiece — hold the phone to your ear to confirm.

MICROPHONE
- Record your voice with a live audio level meter, then play it back to verify recording and playback both work.

PRIVACY FIRST
iDiagnostic runs entirely on your device. No data is ever collected, transmitted, stored, or shared. The app makes zero network requests. Your camera, microphone, and test results stay 100% on-device.

LANGUAGES
Available in English and Vietnamese — automatically follows your device's system language setting.

Perfect for:
- Anyone buying a used iPhone — verify hardware before paying
- Phone repair shops checking refurbished devices
- Developers testing app permissions and AVFoundation behavior
- Tech enthusiasts curious about which cameras their phone has

No ads. No tracking. No accounts. Just a clean diagnostic tool that does one thing well.
