Listen to your racquet and perfect your game!RacquetTune ensures that your racquet is ideally suited to your style of play. Simple and straightforward to use, the app uses the sound generated by tapping the strings to calculate the tension with high accuracy. In addition, the interactive swingweight calculator aids in customizing your racquet to fit your own stroke pattern, while the stiffness calculator allows you to simulate different racquet configurations. RacquetTune not only makes it easier to decide when it is time to restring, it is also an invaluable tool when testing different racquets and strings and in identifying which of your racquets is best suited for different types of games. RacquetTune also allows you to check whether your stringer is consistent in his work. RacquetTune includes the following user-friendly tools:Tension measurement - Quickly determines the tension and stringbed stiffness. - Able to detect changes in tension as small as 0.1 kg/0.2 lb.- An accuracy indicator ensures results are consistent. - Graphical presentation of sound waves helps you find the ideal way of tapping the strings. - Settings can be customized to serve tennis, squash, racquetball and badminton racquets, respectively. - View the tension history for each racquet as a list or a graph.- Email a spreadsheet with test data.Swingweight calculator - Add as many weights as you wish to the frame. - Move and change weights to visualize how swingweight, balance and sweet spot location are affected.- Enter target values for the racquet and let RacquetTune distribute the weights automatically.Stiffness calculator - Simulate various racquet and string configurations- Vary tension, string type and racquet head size. - Shows load-displacement curves, stiffness and elastic energies - Handles the large deformations encountered in actual play View a demo video at racquettune.comRacquetTune has been featured in tennis magazines in USA, Italy, France, Germany, Sweden and Norway. "The app is very, very impressive. I get more tension diagnostic questions than just about anybody in the universe, so this is a very good thing to be able to recommend." Jonathan Wolfe US Racquet Stringers AssociationNote, that the actual string tension in the racquet and the setting seen on a stringing machine are two different things and therefore incomparable - more information can be found at racquettune.com.
The iPhone speed radar - easy-to-use speed measurement in your pocket, anytime, anywhere!A unique, advanced app designed to easily measure the speed of cars, boats, skaters, skiers, cyclists, animals, models, footballs, tennis serves, etc. The system is based on motion detection, enabling you to track a moving object using a hand-held device alone. SpeedClock includes three separate speed measurement tools and two distance estimation tools. Speed Radar SpeedClock uses the camera to detect and analyze motion, and a reference distance to calculate the speed of an object. Define the distance to the object of interest, hold the iPhone still and let the object pass across the the screen. The speed is displayed automatically. SpeedClock is also able to automatically measure the speed and save an image of passing objects. The measurement can be initiated from an Apple Watch and the speed displayed on the watch face. High Speed Video Recording An additional speed tool records and processes a video, which enables SpeedClock to track small, fast object, such as flying balls, that can be difficult to catch with regular motion detection. It also calculates additional parameters like acceleration.Synchronized Timing Gates A third speed instrument uses two iPhone/iPads equipped with motion detection to start and stop the timer and measure the speed. The distance between the devices is used as reference, and the speed is calculated based on the time taken by the object to travel between the 'Start' and 'Stop' devices. The time is transmitted wirelessly over WiFi or Bluetooth. Distance Measurement The stadimeter uses the size of a known object, e.g. a car, to calculate the distance. The clinometer uses your own height as reference, along with the angle of the iPhone, to estimate the distance to a point on the ground. The distances obtained from either tool can then be used to calculate the speed.

The easiest and fastest way to measure jump height! JumpPower automatically detects a jumper in front of the camera and tracks the jump with face detection. No set up or interaction with the app is required and the result is spoken directly after the jump. JumpPower also tracks the acceleration from the crouch position to the peak of the jump, which enables it to accurately calculate the power output of the jumper.
