This app was designed as a data logger for parachute testing to record performance thru GPS and opening shock thru the accelerometers. The data is logged in txt files on the sdcard under the folder "jumplogger" and are easy to open with a spreadsheet application. There is an option to fit the data to the standard atmosphere by correcting for temperature and pressure deviations.
Feel free to write me with any comments/suggestions for improvements.
How to use:
Turn on GPS
Open App
Click start, when light is green, its recording.
