Make one with AI
Audit my PulsHealth heart-rate sources to find external sensor recordings and any simultaneous Apple Watch data. Compare expanded workout streams, not raw HealthKit quantity object counts. Show interval distributions, readings per minute and gaps. If recordings are from different runs, state that clearly and do not infer sensor accuracy or heart-rate agreement. Keep dates, source identifiers and personal attribution private in public output.
