FaceMonitor

Features
Read full description

"Face Monitor" is a lightweight utility application focused on real-time face detection. It operates entirely without a network connection and stores no local data, protecting user privacy from the outset. 【Core Features and Functions】 1. Precise Facial Feature Recognition: Utilizing facial tracking technology, it captures faces in real-time, accurately annotates key facial feature points, and clearly presents the recognition status, providing stable support for subsequent drowsiness monitoring. The recognition process is smooth and lag-free, with higher accuracy in well-lit conditions and when the face is unobstructed. 2. Intelligent Drowsiness Detection and Reminder: After entering monitoring mode, it automatically monitors facial status in real-time, accurately identifying drowsy behaviors such as closed eyes and drooping head, triggering a dual reminder of a pop-up window and a notification sound. The notification sound can be manually turned on or off, and the reminder continues until the user regains consciousness. Suitable for various scenarios such as focused work and study, it helps users stay alert. 3. Intelligent Unrecognized Face Prompt: When facial recognition fails or a face is lost during monitoring (out of frame, obscured), a clear prompt will automatically appear, providing an option to re-recognize. Users can adjust the camera angle and facial pose to quickly restart recognition, ensuring functional continuity and avoiding user experience disruptions due to recognition interruptions. 4. Flexible Parameter Settings: Supports customizable adjustment of core parameters to adapt to different usage scenarios; supports enabling anti-screenshot protection to prevent malicious interception of monitoring footage, further safeguarding privacy. 5. Purely Offline with No Storage Design: No network connection is required throughout the process, and no local storage records are generated. All real-time detection data is only valid within the current usage session and is automatically cleared when the application is closed. No need to worry about data leaks, privacy is better protected, and no photo storage permissions are required, making operation more convenient. 【Application Advantages】 - Lightweight and Smooth: Small memory footprint, stable operation, no lag, compatible with most iOS models, maintaining a smooth experience even after prolonged use; - Simple Operation: No complicated setup required. Simply launch the app and authorize the camera to start using it quickly. The interface is clean and intuitive, easy for beginners to use; - Privacy and Security: Runs offline, no data storage, does not collect any user facial information, and processes data locally in real time, protecting user privacy; - Scene Adaptability: Suitable for legal scenarios such as personal focus reminders and facial status monitoring, meeting diverse real-time detection needs. 【Usage Tips】 Please grant camera permissions before use (no photo storage permission required), ensure sufficient lighting and an unobstructed face for optimal recognition; prolonged use of the monitoring function will consume some battery power, it is recommended to use it while charging or control usage time reasonably; if you encounter any functional abnormalities, please report the problem via email, and we will optimize and fix it promptly. We are always focused on improving the application experience, regularly updating and optimizing functions to provide you with more accurate and convenient real-time facial monitoring services. Thank you for your use and support!

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.
