Chronometer vs QR Code Reader

Chronometer – Mechanical Watch Accuracy This app helps you track the real-world accuracy and long-term rate performance of your mechanical watch. It provides an easy way to measure the daily rate of your watch against an accurate NTP time reference and to follow its performance over days, weeks or months. Before starting a new measurement series, synchronize your watch with an accurate time reference. Do not reset the watch during the measurement period. An internet connection is required to obtain the precise NTP reference time. How to measure your watch 1. Start the app and wait until the NTP server has synchronized. The NTP time turns green when the reference time is available. 2. Point the camera at the watch dial. You can use pinch-to-zoom and, on supported devices, the macro capability for precise reading of the seconds hand. 3. Tap the camera button to freeze the image. The app records the corresponding NTP reference time. 4. Read the exact time from the frozen image and adjust the displayed watch time using the picker wheels. 5. If desired, enter the current altitude above sea level. 6. Tap Save Rate to store the measurement. 7. Tap the camera button again to return to the live camera view. For the best results, measure your watch once per day at approximately the same time. If more than one day passes between two measurements, the app automatically calculates the average daily rate for that interval. Performance evaluation The graph shows the daily rate of your watch together with the standard COSC limits and the more demanding COSC Excellence limits. After at least 15 measurements, the app provides an additional COSC Evaluation based on the most recent 15 daily rate values. The evaluation includes a COSC pass/fail assessment and a Concours Score from 0 to 500 points, derived from the chronometer competition formula. The Concours Score does not include the thermal coefficient (CT). Temperature testing, controlled positional changes, magnetic exposure and shock testing cannot be reproduced during normal everyday use. The result is therefore not an official COSC certification, but a practical evaluation of the real-world rate performance of your watch. The complete measurement history can be exported as a CSV file for further analysis. The exported data includes the date, absolute rate difference, daily rate difference and altitude above sea level. Time reference: Swiss NTP server ntp11.metas.ch The app also includes a COSC NTP 4 Hz reference dial for calibration and verification of optical timing instruments. Requires iOS 18.6 or later.

QR Code Reader: Batch Scanner is a professional-grade utility built for speed, security, and organization. If you are tired of scanning codes one by one or using basic readers that do not save your history, this application entirely changes your workflow. Designed for both everyday users and professionals, it provides a comprehensive suite to capture, create, and manage digital information effortlessly. HIGH-SPEED SCANNING & SECURITY * Batch & Single Scan: Capture multiple codes simultaneously without returning to the home screen, or use the single mode for quick lookups. * Gallery Scanning: Extract data directly from images saved in your camera roll. * Link Security Validation: Automatically check scanned URLs to ensure they are safe before you open them. * Feedback Controls: Customize your scanning experience with adjustable haptic and audio feedback settings. GENERATOR & DESIGN * Multi-Format Creation: Generate codes for any purpose, including URL, Text, Wi-Fi, vCard, Email, Phone, SMS, and Geo-location. * Custom QR Design: Personalize your creations by adjusting colors, modifying visual styles, and adding your own center logos to make them stand out. MANAGEMENT & EXPORT * Scan History Log: Never lose important data. Access a complete record of everything you have scanned. * Node Clusters & Bookmarking: Organize your saved codes into custom folders (Node Clusters) and bookmark your most frequently used items. * Advanced Export: Share your scan history logs via CSV or PDF, and export your custom-designed QR codes as high-quality Image or PDF files. SUBSCRIPTION & ACCESS TERMS Important: Access to the app requires a subscription, and there is no free content available.
