I wish to have an iPhone 4 app that uses both the accelerometer and gyro to get x, y, z and t coordinates for 5 seconds to (say) 10 minutes. It can be gotten each 1/n of a second (e.g. 1/20th of a second), and then have a "start" and "stop" button to turn it on/off, and an email address to send the data to. I would prefer if the data had the coordinates in actual locations per unit of time (e.g. Jan 3, 2011, 5:43:21 pm, with the time going to the 1/100th or 60th or 20th of a second, which is done in iPhone 4).
I'd like it to be a complete, free standing app.
I would pay (say) $500, or give a percentage (1%) of sales -- I'm new at this.
