Health Fusion
Your Apple Health & WHOOP data, unified.
Oliver Posselt
Health Fusion is a native macOS dashboard that brings your Apple Health and WHOOP data together in one place — no browser, no subscriptions, no cloud. At a glance, every day The Overview gives you today's key metrics in a single view: steps, active calories, resting heart rate, HRV, recovery score, sleep duration, and strain. Charts show the past 7 or 30 days at a glance so you can spot patterns without digging. Deep dives when you need them Dedicated sections for Apple Health and WHOOP let you explore each source in detail — heart rate trends, sleep stages, step history, HRV over time, recovery scores, strain, and a full workout log with per-session stats. See what's connected The Correlations view plots your metrics against each other — sleep vs. HRV, strain vs. recovery, and more — with Pearson correlation coefficients and regression lines so you can understand what's actually driving your performance. Sleep, done right Sleep is attributed to the morning you wake up, not the night you went to bed. Duplicate readings from iPhone and Apple Watch are automatically deduplicated. Apple Health and WHOOP sleep are merged, not stacked. Your data stays on your Mac Apple Health data is imported from an export ZIP and parsed locally. WHOOP syncs directly via OAuth. Nothing leaves your machine.
