Every figure here is randomly generated and fictional, included so you can see what combining your own exports would reveal.

Combined Wearables, Correlated (Sample Data)
One view fusing Oura, Whoop, and Google Fit plus a manual log, so you can ask cross-source questions a single app cannot answer.
Oura
Whoop
Google Fit
Manual log
Combined timeline, last 60 days
Three sources on one chart: steps (Google Fit) as bars, sleep hours (Oura) and recovery (Whoop) as lines.
Correlation explorer
Pick any two metrics from any source. The chart plots one against the other, fits a trend line, and computes the correlation.
What the combined view shows
This is the method, not anyone's real data.
Your own exports (Oura, Whoop, Google Fit or Apple Health) would show your real version of every chart above, and combining them is the point: the cross-source questions only make sense once the sources sit side by side. None of it has to leave your machine. Observations here are illustrative, not medical advice.
