About

TrueDetect Device Test

Features
Read full description

TrueDetect Device Test checks the hardware of an iPhone and reports exactly what it measured. Tap Full Test and the app works through the device one function at a time: display and touch, front and rear cameras, speaker and microphone, vibration, buttons, Wi-Fi, Bluetooth, NFC, GPS, the motion sensors, the compass, the proximity sensor, charging, and the battery. Each check ends in a clear result you can read at a glance, and every card can be opened to see the underlying measurement behind it. Two things guide the whole app: REAL READINGS, NEVER GUESSES A value is shown only when the device itself reports it. Where iOS does not expose something, the app says so instead of filling the gap with an estimate. A result you cannot trust is worse than no result. A FINDING, NOT JUST A VERDICT When a check does not pass, the app states what it found - which part, and what was measured - so the reason is on the screen rather than left to memory. Any test can also be run on its own from Manual Test, which is useful when you want to re-check a single function after handling the device. The app is made by K-Device Lab for businesses that inspect used iPhones and need an honest, repeatable record of a handset's condition. It is free, contains no advertising, and offers nothing to purchase.

About

Flip Mirror

Ever felt that your face in photos looks different from your face in the mirror? A mirror shows you left-right reversed. We spend our whole lives used to that flipped version of ourselves, but the face other people see is the opposite. That is why photos of you can feel unfamiliar. Flip Mirror shows you the face other people actually see. โ–  Flip mirror One button switches between Mirror mode and Real mode. Mirror mode is the familiar reflection you know. Real mode is the face others see. Switch back and forth and you will notice immediately how much a left-right flip changes an impression. โ–  Freeze the screen Tap Freeze and the moment holds still. Put your hand down and take your time - useful for checking the back of your hair, your profile, or a new hairstyle. โ–  Save the photo Save the frozen frame to your photo library. It saves exactly as you saw it on screen, so you can save both modes and compare them side by side. โ–  Brightness Adjust screen brightness with a slider. Check your face clearly in a dim room or at night. โ–  3-step zoom Zoom in step by step on the details you want to see up close - eyes, lips, skin. โ–  When to use it Before an interview or a date, to see the face others will see Touching up makeup or fixing your bangs When you wonder why photos of you look off When facial asymmetry is on your mind Checking how you look before heading out When you want a quick look without a hand mirror โ–  No waiting The app opens straight to the mirror. If loading is slow, we show the mirror first instead of making you wait. No sign-up, no login, no complicated settings. โ–  Privacy The camera view is only displayed on your device. It is never stored or sent anywhere. A frozen frame is saved to your photo library only when you tap the save button yourself. The app does not read your photo library or access other photos, and it never requests microphone or location permission. The only permissions needed are camera and photo saving. โ–  Note This app is free and contains ads. Ads are kept to a minimum and never block the screen while you are using the mirror.
