# Shiny Health

## iOS
Apple Health and Google Fit for your .NET7+ .NET Mobile apps

## Features
* Read summary values between timestamps and specified interval
* Query distance, step count, calory intake, & heart rate
* TODO: Write values

## How To Use

```csharp
IHealthService health; // inject, resolve, etc
// request permissions
var result = await health.RequestPermission(
new Permission(DistanceHealthMetric.Default, PermissionType.Read),
new Permission(CaloriesHealthMetric.Default, PermissionType.Read),
new Permission(StepCountHealthMetric.Default, PermissionType.Read),
new Permission(HeartRateHealthMetric.Default, PermissionType.Read)
);
if (!result)
{
// say something useful
}

var end = DateTimeOffset.Now;
var start = DateTimeOffset.Now.AddDays(-1);

// now run your queries
var distance = (await health.Query(DistanceHealthMetric.Default, start, end, Interval.Days)).Sum(x => x.Value);
var calories = (await health.Query(CaloriesHealthMetric.Default, start, end, Interval.Days)).Sum(x => x.Value);
var steps = (await health.Query(StepCountHealthMetric.Default, start, end, Interval.Days)).Sum(x => x.Value);
var heartRate = (await health.Query(HeartRateHealthMetric.Default, start, end, Interval.Days)).Average(x => x.Value);
```

## Setup

### MAUI

Install Shiny.Health from [![NuGet](https://img.shields.io/nuget/v/Shiny.Health.svg?maxAge=2592000)](https://www.nuget.org/packages/Shiny.Health/)

Now, in your MauiProgram.cs, add:

```cshar
public static MauiApp CreateMauiApp()
{
var builder = MauiApp
.CreateBuilder()
.UseShiny()
.UseMauiApp<App>()
.UseShinyFramework(
new DryIocContainerExtension(),
prism => prism.OnAppStart("NavigationPage/HealthTestPage")
)
.ConfigureFonts(fonts =>
{
fonts.AddFont("OpenSans-Regular.ttf", "OpenSansRegular");
fonts.AddFont("OpenSans-Semibold.ttf", "OpenSansSemibold");
});
builder.Services.AddHealthIntegration();
return builder.Build();
}
```

### iOS

To use iOS (and therefore the sample), you need to have a provisioning profile with all
of the necessary Apple Health setup for your application.

Take a look at the Xamarin docs for [more info](https://learn.microsoft.com/en-us/xamarin/ios/platform/healthkit)

Add the following:

#### Info.plist

Info.plist
```xml
<key>UIRequiredDeviceCapabilities</key>

Google Fit

Activity: This captures any activity that a user does. It can include health and fitness activities like running or swimming, meditation, and sleep.
Body Measurement: This captures common data related to the body. It includes capturing a user’s weight, or a user’s basal metabolic rate, among other data types.
Cycle Tracking: This captures menstrual cycles and related data points, such as the binary result of an ovulation test.
Nutrition: This captures hydration and nutrition data types. The former represents how much water a user drank in a single drink. The latter includes many optional fields, from calories to sugar and magnesium that record which nutrients the user consumed.
Sleep: This captures interval data related to a user’s length and type of sleep.
Vitals: This captures essential information about the user’s general health. It includes everything from blood glucose to body temperature and blood oxygen saturation.

An explicit App ID.
A Provisioning Profile associated with that explicit App ID and with Health Kit permissions.
An Entitlements.plist with a com.apple.developer.healthkit property of type Boolean set to Yes.
An Info.plist whose UIRequiredDeviceCapabilities key contains an entry with the String value healthkit.
The Info.plist must also have appropriate privacy-explanation entries: a String explanation for the key NSHealthUpdateUsageDescription if the app is going to write data and a String explanation for the key NSHealthShareUsageDescription if the app is going to read Health Kit data.
