    Measure the speed of tennis shots with your iPhone!
    I should be possible to create such an app because the iPhone has a motion sensor.

    I envision placing the iPhone in a plastic cradle at the end of the court, my tennis partner does the same on his side with his iPhone.
    Both phones talk to each other and recorded the speed. The speed can then be instantly seen on the iPhone, which beeps, to say it has recorded the speed, and better yet the speed numbers are transferred in larger scale to your iPad which resides on the bench, so both players you can read them from their court location.

    I dont understand how your getting all this from an iPhones motion sensor. The sensors in an iPhone include a Ambient light sensor, Proximity sensor, Magnet something sensor, Gyroscope, and an accelerometer. NONE of these sensors measure speed. Using the word " motion sensor " is way too broad to even think about when trying to make such a thing. Even so with your misinterpreted motion sensor how would this work?
    Okay you leave a phone on the floor -> phone somehow records the speed with motion sensor you are speaking of? -> Transferred over to a larger platform just to read numbers and both players can read it?
    Why do they have to be at the ends of the court? Is it possible to do with only one phone for those who dont have 2 devices on hand?
    What process goes on when they are talking to each other? Are they communicating time taken to travel so and so distance?
    Okay i get that it beeps to notify you.
    Why cant the numbers be transferred over to the phones that are already on the floor beside you? I'm probably picturing this wrong.
    Its possible to use time taken to travel a certain distance but that wouldn't be taking in account of spin and when it hits the floor and reduces speed. But using a motion sensor that is made up by the things i listed above isnt possible to create an application that would be able to measure speed of a ball.
    If it was so easy to use a phone to measure MPH, there would have been many apps already out there by now.
    Maybe someone else would chime in to tell me im wrong.
