Made me notice my fatigue

I have used this app for a while now and am impressed by it's simplicity. Its fatigue detection is quite accurate. Sometimes when I find myself feeling very tired around midday and look at app, it actually shows a dip in my fatigue score.

I use a Fitbit Versa 2 to track my data and I see this app also supports Garmin, which is great. But it would be great if we could use this app without requiring a tracking device. What if I wanted to switch to a different tracker like an Apple watch?

Keeps improving

Glad to see updates!
Old review: The app is good. But the new view makes it harder to see the exact same stuff. I agree with having a trends button to see extra information (and further into the past, please) but I shouldn't have to go there to see things that used to be on the home screen.

Logs me out of app randomly

When it works it’s great but from time to time it logs me out of the app and I can’t log back in. Instead of logging in with username and password it promps you to put in your email so it can send you a link. Well no link is ever sent making it impossible to sign in for days on end.
