- 30-day and 90-day trend analysis
- One-year chart history with target-range band and period stats

Subscription/lifetime unlock through RevenueCat (any active entitlement unlocks):

Free users see a locked teaser card and locked Settings toggles that open a focused paywall. Trial copy only appears when StoreKit intro eligibility is confirmed (Apple 3.1.2).
VO2 max values are Apple Health estimates, not medical measurements. The app is for fitness awareness and does not diagnose, treat, or predict health conditions.
xcodegen generate
UDID=$(agent-sim boot vo2max)
xcodebuild -project VO2Max.xcodeproj -scheme VO2Max -destination "id=$UDID" build
xcodebuild test -project VO2Max.xcodeproj -scheme VO2Max -destination "id=$UDID"For a populated simulator UI, add -DemoData to the scheme launch arguments.
Set RevenueCatConfig.publicSDKKey to the app-specific public key beginning with appl_. Never place a RevenueCat secret key beginning with sk_ in the app or repository. The simulator intentionally skips RevenueCat configuration and uses the local Pro override in Settings.
