After the last update, 01/25, I wasn’t able to access the app. When it finally loaded all the pages were blank. After I rebooted the phone, got through the introductory pages, and used my Apple ID to sign in, it kept reloading to the sign in page. I deleted the app since it was no longer useful. A shame really, I spent a lot of time uploading my medical records/history from the last 8 years. I’m not wanting to do that again.

It's an interesting app that competes with others in this space, such as Gentler and Athlytic. In vomparison with these apps, it offers more detailed analysis although I'm not sure what value this is bringing.. The interface can be confusing, the app tends to crash, and the longevity score seems bugged, at least for me. Also concerning is that the analysis leads you to numerous products for purchase; not sure what that's all about anyway, As I said, it's an interesting app, but it needs work and I'm not sure if I would end up replacing any of its competitors for this. (One more note, the myriad of five star reviews are highly suspicious. That's very much offputting to me.)

the app provides a comprehensive level of analysis above apple health, which is awesome. i love the journeys feature (even though there are only two right now) because they actually help me improve my metrics (rhr, hrv, etc) instead of most apps like whoop which simply provide analysis. with that being said, i’m looking forward to more features in the app that are planned, particularly social features and more journeys!
