Shiny.Health is a mobile-only library. macOS, Windows, Linux, and Blazor WebAssembly are not supported — there are no equivalent health data APIs on those platforms.

Shiny Health provides a unified API for reading and writing health data from Apple HealthKit (iOS) and Android Health Connect. It supports permission management, time-bucketed aggregate queries, data writing, and 30+ cross-platform health metrics spanning activity, body, vitals, nutrition, reproductive/cycle tracking, and workouts.

Features

• Single IHealthService interface that works on both iOS and Android
• Read and write support for 30+ cross-platform health metrics
• Real-time observation of health data changes via IAsyncEnumerable<HealthResult>
• Time-bucketed aggregate queries at minute, hour, or day intervals
• Permission management with per-metric read/write granularity via PermissionType
• AOT-compatible implementation (no .NET reflection)
• Blood pressure returns a dedicated BloodPressureResult with separate systolic/diastolic values
• Reproductive & cycle tracking (menstruation flow, sexual activity, ovulation tests, cervical mucus, intermenstrual bleeding), plus workouts and nutrition via dedicated result records
• Optional Microsoft.Extensions.AI tools via Shiny.Health.Extensions.AI to expose health data to LLM agents

Supported Metrics

Metric	Unit	iOS (HealthKit)	Android (Health Connect)
Step Count	count	HKQuantityType.StepCount	StepsRecord

Resting Heart Rate	bpm	HKQuantityType.RestingHeartRate	RestingHeartRateRecord
Blood Pressure	mmHg	HKQuantityType.BloodPressureSystolic/Diastolic	BloodPressureRecord
Oxygen Saturation	%	HKQuantityType.OxygenSaturation	OxygenSaturationRecord
Sleep Duration	hours	HKCategoryType.SleepAnalysis	SleepSessionRecord
Hydration	liters	HKQuantityType.DietaryWater	HydrationRecord
Blood Glucose	mg/dL	HKQuantityType.BloodGlucose	BloodGlucoseRecord

Power	watts	HKQuantityType.CyclingPower	PowerRecord
Menstruation Flow	flow level	HKCategoryType.MenstrualFlow	MenstruationFlowRecord
Sexual Activity	protection enum	HKCategoryType.SexualActivity	SexualActivityRecord
Ovulation Test	result enum	HKCategoryType.OvulationTestResult	OvulationTestRecord
Cervical Mucus	appearance enum	HKCategoryType.CervicalMucusQuality	CervicalMucusRecord
Intermenstrual Bleeding	event	HKCategoryType.IntermenstrualBleeding	IntermenstrualBleedingRecord
Workout	session	HKWorkout	ExerciseSessionRecord
Nutrition	food/macros	Food correlation	NutritionRecord

Categorical, event-based & structured metrics are different

Menstruation flow, sexual activity, ovulation tests, cervical mucus, intermenstrual bleeding, workouts, and nutrition are not numeric. Each uses its own result record (e.g. MenstruationFlowResult, SexualActivityResult, WorkoutResult, NutritionResult), has no Interval bucketing, and is read via a dedicated method (GetMenstruationFlow, GetSexualActivity, GetWorkouts, GetNutrition, …). The MenstrualFlow.None level and IsCycleStart flag are iOS-only.
