I’ve spent a few days exploring [Google Fit SDK] as I try to wean myself from my obsession with metrics (of all forms). A quick Googling got me to Robert’s Exporter Google Fit Daily Steps, Weight and Distance to a Google Sheet. This works and is probably where I should have stopped… avoiding the rabbit hole that I’ve been down…

I threw together a simple Golang implementation of the SDK using Google’s Golang API Client Library. Thanks to Robert’s example, I was able to infer some of the complexity this API particularly in its use of data types, data sources and datasets. Having used Stackdriver in my previous life, Google Fit’s structure bears more than a passing resemblance to Stackdriver’s data model and its use of resource types and metric types.
