cyclingCadence: HealthKit quantity type
HKQuantityTypeIdentifierCyclingCadence · read from Apple’s documentation on 2026-10-02
HKQuantityTypeIdentifier.cyclingCadence (Objective-C HKQuantityTypeIdentifierCyclingCadence) is a HealthKit quantity type in Apple's "Activity" group. Apple's abstract: “A quantity sample type that represents the rate at which the user is pedaling.” Apple's discussion says its samples use counts per minute units and measure discrete values, so in HKStatisticsQuery it takes .discreteAverage, .discreteMin or .discreteMax. It is available from iOS 17.0 and watchOS 10.0.

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
discrete — in an HKStatisticsQuery, use .discreteAverage, .discreteMin or .discreteMax. Apple’s sentence:
These samples use counts per minute units (described in ) and measure discrete values (described in ).
Unit family
counts per minute — 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 cyclingCadence?
Apple’s documentation for cyclingCadence 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 cyclingCadence is not among them. A similarly named Health Connect record may exist, but a name match is not a verified mapping.
Questions
- Should I sum or average cyclingCadence in HealthKit?
- Average it, or take its minimum or maximum — do not sum it. Apple's documentation for cyclingCadence describes it as measuring discrete values, so an HKStatisticsQuery over it takes .discreteAverage, .discreteMin or .discreteMax. Apple's sentence, as read on 2026-10-02: "These samples use counts per minute units (described in ) and measure discrete values (described in )."
- Which unit family does Apple give cyclingCadence?
- Counts per minute. Apple's discussion of cyclingCadence says its samples use counts per minute units: "These samples use counts per minute units (described in ) and measure discrete values (described in )."
- Which iOS version added cyclingCadence?
- iOS 17.0. Apple's availability data for cyclingCadence lists iOS 17.0, iPadOS 17.0, Mac Catalyst 17.0, macOS 14.0, visionOS 1.0 and watchOS 10.0.
