GC Notio is a fork of GoldenCheetah which is an open-source data analysis tool primarily written in C++ with Qt for cyclists and triathletes with support for training as well.
GoldenCheetah can connect with indoor trainers and cycling equipment such as cycling computers and power meters to import data.
As the original GoldenCheetah, GC Notio can connect to cloud services including Notio and Legacy Notio Konect clouds.
It can then manipulate and view the data, as well as analyze it.
This paticular fork allows to analyze the Notio device data to determine your CdA.
GC Notio install and build instructions are documented for each platform;
INSTALL-Notio-WIN32 For building on Microsoft Windows 64bits
INSTALL-Notio-OSX For building on Apple OS X
As not been tested on Linux yet. Future development.
