### 3/5 — Login issues

*2024-12-29, version 1.0.7*

The app is fantastic when it’s working. However, when I try to log in, I’m immediately returned to the login screen after entering all my correct login info.  This issue seem to come with the latest update

### 5/5 — Just what I was looking for

Relatively simple app that takes my data from the heinous intervals.ICU website and puts it into an easy to read format on my phone.

### 1/5 — Login does not work

 version of intervals icu however whenever I login through the app it registers as successful but then it simply redirects back to the login page. I have the iPhone 14 Pro.
