Hi there @erik ,
as the creator of quantified-self.io and sports-alliance/sports-lib and fit-file-parser (used by this proj) I would mostly welcome you to join sports-alliance with @thomaschampagne
Quantified-Self.io is opensource based on Firebase and Angular.
I can go on an integrate this there as a module, but I would like to hear your thoughts first
Kr,
Dimi
