What is DotnetWorkoutKit?

DotnetWorkoutKit is a cross-platform .NET library that provides a way to create custom workout files for Apple Watch.

Goals

Apple announced the library WorkoutKit in WWDC 2023, which allows developers to create and preview workouts in your iOS and watchOS apps. Refer to the WWDC23 session 10016(timecode: 09:43), the .workout file can be in both binary and JSON format.

However, Apple changed their decision, when the WorkoutKit was officially released, the .workout file is in binary format only. See this reply for more information. This means that developers can't create custom workouts outside of Xcode and MacOS.

So I decoded the binary format of the .workout file and created this library to provide a way to create custom workout files.

Features

• Create a CustomWorkout with C# code.
• Save CustomWorkout as a .workout file, which can be previewed on your iPhone and imported to Apple Watch.

Limitations

• Only support the CustomWorkout type.
• Only support outdoor running for now.
• Only support HeartRateRangeAlert and SpeedRangeAlert for now.

Using DotnetWorkoutKit

1. Create a CustomWorkout and save it as a .workout file.

using DotnetWorkoutKit.Extensions;
using DotnetWorkoutKit.Models;

var customWorkout = new CustomWorkout(
        CustomWorkout.ActivityType.Running, 
        CustomWorkout.LocationType.Outdoor,
        "E8k Interval",
        new WorkoutStep(new DistanceGoal(2, DistanceGoal.DistanceUnitType.Kilometers), null, "warm up"),
        [
            new IntervalBlock([new (IntervalStep.PurposeType.Work, new (new DistanceGoal(8, DistanceGoal.DistanceUnitType.Kilometers), new HeartRateRangeAlert(144, 153)))], 1),
            new IntervalBlock([
                new (IntervalStep.PurposeType.Work, new (new DistanceGoal(100, DistanceGoal.DistanceUnitType.Meters), new SpeedRangeAlert(11, 12))),
                new (IntervalStep.PurposeType.Recovery, new (new TimeGoal(TimeSpan.FromMinutes(2))))
                ], 8)
        ],
        new WorkoutStep(new DistanceGoal(2, DistanceGoal.DistanceUnitType.Kilometers), new SpeedRangeAlert("5'40\"", "5'20\""), "cool down"));

// Save to file
File.WriteAllBytes("test.workout", customWorkout.DataRepresentation());

2. Share the .workout file to your iPhone through AirDrop or other methods.

3. You can preview the workout on your iPhone and import it to Apple Watch.
