When in doubt, report it anyway — a duplicate costs seconds. This page exists to
save you effort, not to discourage you.
Deliberately inert
- Vitality Score shows nothing. Platform-computed, awaiting a biomarker set that does not sync yet. Explained here.
- Symptoms opens but stays empty. Same reason.
- Sleep Debt is never shown. Computed, but its constants are not calibrated.
- Naps are drawn but never scored. Deferred deliberately.
- Glucose shows first and last meal only, not individual meals. Per-meal detail arrives with the consumer app.
Device limitations, not app faults
- Apple Watch shows a dash for Time to Sleep. Apple does not provide it. Permanent.
- Polar shows no naps, ever. Polar’s service has no place for them.
- Polar app effort ratings do not arrive. Their interface does not carry them.
- Fitbit sleep reads better here than in the Fitbit app. The iPhone route drops restless time.
- Oura is the only source with a Movements strip. Nobody else provides it.
Expected behaviour that looks wrong
- Sleep differs from Apple’s Health app. We show the Watch alone; Apple blends every source. Deliberate.
- Sleep scores differ from your device’s own. Different published methods, and the app labels which it is showing.
- Blank cards in your first two weeks. Baselines need history.
- Respiratory rate and heart-rate dip blank for a fortnight. Same.
- SHI showing progress instead of a score. Needs 14 usable nights in 28.
- Google Health going blank about weekly. Testing-stage access expires. Reconnect.
- Capacity moving more than you expect. It is in calibration — though a figure that is clearly wrong for an explicable day is worth reporting.
Things that are not bugs at all
- A gap on a night you did not wear the device. That is data.
- A build expiring after 90 days. Apple’s rule.
- The orange dot beside the app name. It means “installed from TestFlight”.
Always worth reporting
- Crashes
- Data on the wrong day
- A figure that cannot be right
- Something that worked and stopped
- Two places in the app disagreeing
- Anything you find confusing — including a page on this site that is wrong or unclear
