Capture my iPhone accelerometer readings

Overview ======= I want to capture my iPhone accelerometer readings to a file for later analysis Requirements ========== I want an iPhone app that enables the following workflow: 1) I invoke the app, and touch a START button 2) The accelerometer readings are captured, at the highest possible sensitivity, and at the highest possible time resolution 3) I touch the STOP button, up to 10 minutes later 4) A CSV file has been created, containing the timestamped x, y, and z readings of the accelerometer at the highest sensitivity and time resolution I'm open to different ways of achieving this workflow. For example, the CSV file could be created locally on the iPhone, or the data could be streamed wirelessly to a client that is listening at a remote server (I'll take care of creating such a client, it's not part of this project), or even using the USB connector to stream the data to a file on a laptop in my backpack, etc. or some other solution that achieves the workflow. Additionally: 1) All the source code will be well-documented 2) You will write detailed instructions for deploying and using the source code 3) This will be a "work made for hire," meaning that the copyright and all other rights to the source code, etc. will belong to me upon my paying you for this job. I'll need you to sign an agreement to that effect as a condition of you starting this job.
