This app gives you detailed information about your workouts and offers comprehensive analysis of your performance. So far there is one issue that bothers me. I currently live in China, the Chinese government requires all domestic mapping services to use a coordinate system called GCJ-02, which differs from WGS-84. This results in a fixed offset of workout routes displayed in the app. I wonder if you could look into it and come up with a transformation of the two coordinate systems, so that I can see my workout route clean and neat. Much appreciated. -- clatosklisto, 2026-07-17 ### ***** "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! -- Occipital King, 2026-04-20 ### *---- "Tip jar spam" Having to dismiss the tip jar pop up constantly made me uninstall the app. -- jstewartmitchel, 2026-03-23 ### ***** "Freaking Awesome!" Yep -- aiwetir, 2026-02-09 ### ***** "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. -- Runner Kenwood, 2026-01-16 ### ***** "All the stars" Amazing app. If you use Intervals.icu then this is the app you need -- BenjaminPoiesz, 2025-11-17 ### ***** "Incredible App" Wow, this is an amazing app. Much better interface than the official website. Ps, I also ride the PMC! For almost 20 years. -- Prophotog10000, 2025-06-17 ### ***** "goated app" Honestly everything I was looking for in terms of an iphone app for this niche, just an extra bonus in that it actually has widgets and apple specific stuff that’s useful. -- SovietBear462, 2025-04-08 ### ***** "Awesome!" Really great app! -- AJMB18, 2025-02-15 ### ***** "Amazing app!" This app is amazing it takes all of my fitness needs into one app! Love this app so much definitely recommend it! -- bsbsggsgsg, 2025-02-01 ### ***** "Just right!" This app fills a much needed gap perfectly! I use intervals.icu as my primary workout/fitness planning and tracking hub, but until Intervals Companion the only way to view my stats was through the web app. With Intervals Companion I can load up my Home Screen and my Apple Watch face with beautiful widgets that update instantly after I complete a workout! If you use intervals.icu this app should be considered mandatory. The developer did a great job keeping the app laser focused and lightweight too, so you don’t have to worry about battery drain.
