Tired of developing your own recording platform for research?
Here is one that is better than any other app in the market. I tested them all.

The app allows the recording of motion and location data
- Accelerometer
- Gyroscope
- Magnetometer
- Location

Share the data using Airdrop or Dropbox. Autoupload the data at a desired frequency to you dropbox account.

Continuous use of location services in the background may drain the battery faster.
