Flawless Integration with Apple Health

I use an Apple Watch and had been recording most of my workouts natively on the Workout app along with the Apple Health app. As I started to get a bit more serious with my training I decided I wanted more stats and load estimations to better guide my training and that’s when I created an Intervals.ICU account. Well, this app made the exporting of my data to Intervals.ICU seamless. Love the app, totally recommend!

You need this if you Zwift

This app is amazing if you use Zwift and have an Apple Watch. It provides all the data you could ever need in an easy to use format and uploads it to Apple Workouts. It gives me all the data my Apple Watch cannot provide.
