Project Description

We need you to write iPhone (iOS) and Android apps to measure the location, accelerometer and magnetic data from the phone's sensor and send it to a sever at a regular polling interval or at a rate set by the user. The app should work in the background. Find way to minimize battery use. The App should also plot a map with color icons for each magnetic points (sent from the server). More details later. We would like this project to be completed as soon as possible with 10% bonus for completing it in time.
