💤 WHOOP Dashboard

A personal health command center built on top of the WHOOP API, adding the sports-science analytics (training load, HRV readiness, sleep debt, correlation analysis) that the WHOOP app itself doesn't show.

The problem

WHOOP shows me today's recovery score, but never answered what I actually cared about: am I training smart, or quietly building up an injury? A single number does not show whether this week's load is creeping up too fast, or if last night's bad sleep is connected to tomorrow's performance. I was flying blind on the trends that matter most.

The approach

So I built a dashboard on top of my own WHOOP data that answers the bigger questions. It calculates the same metrics coaches actually use: acute-to-chronic training load ratio (7 days versus 28, the method used to flag injury risk in elite athletes), HRV measured against my own baseline instead of a generic range, and the real statistical correlation between my sleep debt and next-day recovery.

The result

Now I open one dashboard and see the full picture: a daily briefing on what to prioritise, full history for Recovery, Sleep, Strain, and Performance, and a page showing exactly which sports-science research (Plews 2013, Gabbett 2016, Banister 1975) each metric is built on. Installed on my phone, so "push hard or back off" is one tap away instead of a guess.

Screenshots

All screenshots below are of the live dashboard rendering my own 167-day WHOOP history, not sample data.

Mission Control home screen with recovery, strain, and sleep rings, a daily briefing, and priority actions
Mission Control
The home view: recovery, strain, and sleep as live rings, a plain-language daily briefing summarising 167 days of history, and priority actions ranked by what actually matters today.
Recovery page with HRV baseline band, resting heart rate, SpO2, and full history charts
Recovery, full history
HRV plotted against a personal baseline band rather than a generic range, alongside resting heart rate, SpO2, skin temperature, and a training readiness score exclusive to this dashboard.
Sleep page showing cumulative sleep debt, REM hit rate, deep sleep rate, and sleep performance history
Sleep intelligence
Cumulative sleep debt tracked in hours, REM and deep sleep hit rates against thresholds, and a stated correlation coefficient between sleep performance and next-day recovery, insights not available in the WHOOP app itself.
Strain and activity page with daily strain history, acute vs chronic training load chart, and sport type breakdown
Strain and training load
Daily strain history alongside a 7-day acute vs. 28-day chronic training load chart (ACWR), plus a full sport-type breakdown across 165 logged sessions.
Performance Intelligence page citing peer-reviewed sports science formulas for HRV readiness, ACWR, and training monotony
Performance Intelligence
Every formula on this page cites its source: rMSSD-based HRV readiness (Plews et al. 2013), the ACWR sweet spot (Gabbett 2016), and the Banister impulse-response training load model, with Pearson correlations run on my own data.
Mobile PWA view of the dashboard with bottom tab navigation, installable to a phone home screen
Installed as a PWA
Responsive down to phone width with bottom tab navigation, installable to a home screen so it opens like a native app rather than a browser tab.
