Nightguard

This is an iPhone and Apple Watch application to display blood glucose values stored at your nightscout server.

Description

Disclaimer! Don't use this App for medical decisions. It comes without absolutely no warranty. Use it at your own risk!

Nightguard is an app that displays your blood glucose values from the Nightscout backend.

It is a native iOS App with support for the Apple Watch. Features are:

Define a range of acceptable blood glucose values.
Whenever your values are out of range you will be alerted.
You can snooze the alerts all the time and for a defined time period.
You can reactivate the alerts all the time.
You can activate alerts if the values are rising or falling too fast.
The app displays yesterdays values as an overlay chart. This way you have a hint about how your values could behave in the future.
Tune your basal rates with the statistics function to overlay different days

For the alarms to work the app has to be active. So you can enable a screen lock that keeps the app running all night long.

Have a look at https://nightscout.github.io for more information about how to setup your own Nightscout backend.

The dark gray region in the chart marks the values that are between 80 and 180.

Developer Hints

First install cocoapods and do a

pod install

afterwards.

Then simply open the Nightguard folder "nightguard" in xcode. If no scheme "nightguard" is existing, select "new Scheme" from the "Product|Scheme" Menu.

I had to modify the Eureka SliderRow. If you would like to compile the project of your own, you will have to modify the SliderRow in the following way:

public final class SliderRow: Row<SliderCell>, RowType {

    public var steps: UInt = 20
    public var shouldHideValue = false
    public var lastSelectedValue : Float?

    required public init(tag: String?) {
        super.init(tag: tag)
    }
}

Now you should be able to launch the app in the simulator. Happy Coding!

Uploading the app

If you would like to run a local compiled version, you might wan't to disable the critical notification entitlement. This can be done in File nightguard/scoutwatch.entitlements by changing the value to false:

    <key>com.apple.developer.usernotifications.critical-alerts</key>
    <false/>
