HKQuantityTypeIdentifierNikeFuel · read from Apple’s documentation on 2026-10-02
HKQuantityTypeIdentifier.nikeFuel (Objective-C HKQuantityTypeIdentifierNikeFuel) is a HealthKit quantity type in Apple's "Activity" group. Apple's abstract: “A quantity sample type that measures the number of NikeFuel points the user has earned.” Apple's discussion says its samples use count units and measure cumulative values, so in HKStatisticsQuery it takes .cumulativeSum. It is available from iOS 8.0 and watchOS 2.0.

Sum or average, and in which units
Apple states both of these in the prose of the type’s discussion, not as properties, so they are derived from Apple’s sentence and the sentence is shown with each.
Aggregation style
cumulative — in an HKStatisticsQuery, use .cumulativeSum. Apple’s sentence:
These samples use count units (described in ) and measure cumulative values (described in ).
Unit family
count — every type in this family is on the HKUnit reference.
Apple states it in the same sentence as the aggregation style, quoted above.
Empty parentheses and a dangling “described in” mark links in Apple’s sentence to other documentation pages: the generator keeps the sentence’s text, not its links, and the quote is left as stored rather than repaired.
Can apps write nikeFuel?
Apple’s documentation for nikeFuel does not state that its samples are read-only. Apple states read-only status only in prose, and its silence is not a statement either way, so this page makes no claim that apps can save it.
On Android Health Connect
No verified Health Connect counterpart. The cross-platform matrix pairs only metrics checked against both Apple’s and Google’s documentation, and nikeFuel is not among them. A similarly named Health Connect record may exist, but a name match is not a verified mapping.
