Machine learning in predicting fitness wearable device data

I used machine learning to predict Jawbone's fitness wearable device based on recorded smartphone sensors. Even basic Android phone has built-in sensors for tracking ambient temperature, device orientation, acceleration and many more. I made the tiny application to record sensor data and log it into a file. This app is a service continuously running in background and tracks my phone sensor's data. I also wear Jawbone UP fitness tracker in same time. It records my steps and activity.
