Illuminance Pulsation Meter vs APSI Bench

The application will help you choose a lamp, monitor or laptop with a screen without pulsations. A high coefficient of pulsation can affect fatigue, well-being and eye strain. The application allows you to measure the ripple coefficient of radiation sources in the visible spectrum: - LED, halogen, fluorescent lamps and incandescent lamps - various lamps - LCD and LED monitors and TVs The readings are not 100% reliable and the average error depending on the light source and the frequency of pulsation can be more than 10%. In order to take measurements, you need to bring the phone to the measured source and press the start button. The measurement results will be updated in real time, the arrow will show the ripple factor, and the scale will be filled from green to red. For best results, keep your phone straight. If the phone is not fixed, an image of the shaking device will appear in the lower left corner of the screen and the readings will be very different from the actual ones.

This app is aimed at interested users and testers who want to test the performance of the integrated CPUs. For this purpose, it offers a mixed test for single-core and multi-core CPUs, as they also occur in real life. In the single core test, the app calculates ten million random numbers from a total of six different data types (Int, Float, etc.). Such calculations are crucial for game apps. APSI Bench then calculates one million FFT transformations that are common in audio applications, for example. In addition to this, the app also runs a ray tracing algorithm that uses several CPU cores at the same time. You can set how many cores should be used here. The results of these tests are based on a reference system (currently a Macbook Pro 16 inch with an eight-core Intel i9 CPU). That reaches about 100 points. Every user of the app can test the ratio of their Apple product to the MacBook Pro. A decisive extension is the newly built in long-term measurement. Here the app carries out the ray tracing tests with all available CPUs over a long period of time that can be set by the user (up to 30 minutes). The result is then displayed in graphic form. If problems arise with overheating of the CPU cores, this will be visible in the graphic. Finally, the app is also a technology demonstration. The entire interface was designed in SwiftUI 2, with gorgeous animations being used. The app will also be offered as a universal app for macOS.
