Nike Fuel

NikeFuel records the number of activity points earned under a source's NikeFuel system. Apple defines it as a cumulative count quantity, rather than a physical measurement. A point is not a step, calorie or exercise minute, and HealthKit does not specify a conversion between them. Apple documents the quantity.

The identifier remains in the current HealthKit SDK without an API deprecation annotation. That does not establish whether an older device, account or app still produces new points. Existing historical records and a currently active data source are different questions. Review the contributing app and the dates of its last entries before expecting a continuing series.

Sum compatible contributions within a source and a reporting window. If two apps import the same activity, adding both can double count it. A large record might be a daily summary rather than an unusual workout; inspect duration and source before treating it as an outlier. Irregular entries can reflect imports or synchronization, so entry spacing does not establish movement cadence.

Steps and active energy can describe activity alongside points when dates and coverage match. Their different definitions prevent a universal conversion or a shared normal range. A source-specific trend can be more useful than a target copied from a different scoring system.

The reviewed 365-day example-data window contained no samples, stored aggregates or workout-series points for this type. Value distributions, unusual readings, recording cadence and related-data comparisons could not be measured. No empirical figure is presented; missing database rows do not establish missing records on the phone.

This identifier is part of HealthKit, but is not listed in the current PulsHealth sync catalog. The units above describe HealthKit measurement semantics rather than a promised sync format. Database coverage and Apple Health availability are separate questions.
