Simple script to combine the accurate GPS data from a Locosys GT-31 and the various data recorded simultaneously with a mobile phone (which may include less-acurate GPS, heart-rate, stride, bike speed, bike cadence, bike power, etc).
Currently only supports data collected with the Wahoo Fitness App on iPhone, but other data collection apps can be added if example output files are provided to me. Additionally, I only have HR and bike cadence speed sensors, so power and stride are implented provisionally and may not work.
