BodyState

I particularly like that it show and uses fatigue (acute training load).

I love this app. It works great and it's amazing that it’s free. Can you add an Apple Watch widget? That would be the perfect cherry on top.

This is quite good for a simple overview. For someone coming from body battery this is really legible, but for someone like myself this is actually pretty difficult to wade through because the information area relates more of why things are measured and how they are averaged than actually teaching us what the information means and how we can use it and why it is measured. I had to research body battery itself to understand what I needed. While the main overview is simple and to the point, which is a positive imo, but it is almost too simple. I can see a history, or graphs, or deeper insights. There is a niche for this app where it can present information on the surface similar to body battery, but then can be dug into to show information in a manner similar to Whoop or Athlytic. TLDR: don’t treat this app like everyone will already be familiar with Body Battery. Educate us fully like we are dummies because most people using this will have always had Apple Watches and therefore won’t have used body battery before.

I’ve never used an app that is this useful for only having one screen of data. The algorithms that determine your baseline RHR and HRV only during sleep and then show your values for the previous night are really useful, this data is more meaningful than just looking at what is displayed in the apple health app, since the default health app data is 24/7 and I specifically want to see what my HR and HRV was at rest to estimate my recovery. The latest update fixed the stuck on “fetching data” bug so ignore the first round of bad reviews for that. The BodyState value itself is accurate too, I’ve been close to 100 on good days, and very low on days when I had poor sleep and bad recovery, so this definitely matches the relative accuracy of Garmin body battery. You should include a tip jar in the app, this is really useful for a free app!

Awesome so far, the update today cleared up issues and it’s working better. Looking forward to Apple Watch complications!

It is a great app and easily to navigate. But I could not see the full sleep baseline due to the length and body state history. Also, it will be better to give any suggestions for the improvement. If those problems could be solved, I would love the app!!
