The app is designed to calculate the number of turns when winding an inductor (inductance coil). A MAGNET SHOULD BE ATTACHED TO THE ROTATING PART. The app (by means of the built-in smartphone magnetic field sensor) determines the number of rotations of the magnet and, therefore, the number of coil turns. It is also possible to determine the rotation of a smartphone without using the magnet (e.g., ... - More info on Turns Counter (Magne...

IMPORTANT!!! Paid version of the "Video tachometer" app, without in-app purchases. For cases where the app is distributed using various services where in-app purchases are not possible. When the frame rate of a video matches the speed of a particular part, the effect is the same as using a strobe light. In the video, that part freezes. Since the frame rate of a video can be adjusted, this effect... - More info on Video tachometer for...

Copy your photos and videos from the iOS "Photos" app to an ORDINARY memory card (or an ORDINARY USB flash drive). From memory cards, photos can be copied to a desktop PC/laptop, or you can use your memory card for storing your photos and videos. All files are copied. For Live Photo, a photo file and a video file are copied. For edited photos and videos, the edited file and the original file are c... - More info on Offline Photo Storag...

A TALKING VERSION OF ANOTHER SPEEDOMETER. DOWNLOAD OUR FREE SPEEDOMETER TO TRY OUT THE KEY FEATURES. 1. Voice cues to notify you when you reach the selected speed. About 25* languages supported. Receive speed voice cues while listening to music. 2. Speed data filtering. Readings with the filter on are more inert than those with the filter off though. THE FILTER MUST BE ON WHEN CYCLING, JOGGING O... - More info on Talking Speedometer...

The application is designed for analysis of a sound spectrum in real time (with a microphone). Besides, the application can be used as a measuring instrument of noise level (not for exact measurements). • Sound wave. • Fast fourier transform (FFT). FFT size: 2048 (the accuracy of determining the frequency of ±12 Hz), 4096 (±6 Hz), 8192 (±3 Hz), 16384 (±2 Hz), 32768 (±1 Hz), 65536 (±0.5 ... - More info on Sound Spectrum Analy...

The app transmits the screen image from iPhone/iPad to another iPhone/iPad. In other words, it is a screen mirror for two iPhone (it is possible to broadcast the screen image simultaneously to several iPhones/iPads). The two devices use peer-to-peer Wi-Fi, which allows the devices to communicate directly, even if they are not on the same Wi-Fi infrastructure network. This technology is used by Air... - More info on Screen Mirroring to ...

1. Step-by-step audio notifications once you have reached your required speeds. 2. Speed data filtering. Readings with the filter on are more inert than those with the filter off though. THE FILTER MUST BE ON WHEN CYCLING, JOGGING OR WALKING. 3. The G-meter. Get APPROXIMATE acceleration calculated based on your speed variation. Why use the GPS G-meter: no need to keep your iPhone in a fixed posi... - More info on Speedometer, Speed L...

The application analyzes the data from the phone's accelerometer and builds a vibration spectrum. This allows the evaluation of not only the strength and frequency of the vibration, but also the speed of rotation of various mechanisms: fans, motors, various rotating components; since the vibration frequency often (but not always) coincides with the frequency of rotation. The application will be us... - More info on Vibration analysis...
