This is great.
You mentioned that the app calculates drift using apple workout history. If I am using Coros watch or let’s say Wahoo app, how do I get the data into this app? Do I have to sync with the Apple Health app on the phone?
Hey everyone, last week I coded an IOS app that calculates you heart rate drift based on your apple workout history. I basically made it for myself so I wouldn’t have to pay for the training peaks premium account. Now I can test my aerobic threshold periodically to monitor my progress.
I’m wondering if anyone else would want to use the app? If I get enough responses I’ll put in the effort to getting it on the IOS app store, otherwise it will remain a personal tool.
Screenshots of the app UI as it stands. You basically do the HR drift test as you normally would, then in the app select the time range that you want to calculate HR drift for. If your run includes a warmup and cooldown, cut that time off.
Currently this only works for outdoor runs since it calculates your pace, but I could easily add the functionality for treadmill tests as well.

Hey Shashi, glad you’re into it! Yes thats right. The app will work with any watch that can sync with apple health, since I built the app using Apple HK Framework.
For athletes who do not have a TP premium account, this app will be helpful.
