It's a wonderful interface to intervals.icu. The stats and tracking are clear even on a tiny phone screen. Some things, like adding some activities is easier in this app than directly in Intervals. There are a small number of things I wish it had. I hope that over time they get added as the author is active and responsive in the Interval forums. There are some minor bugs, like discrepancy between Intervals and this on the profile. Which is why I'm giving it a 4, for now.

i have been using the web interface and am impressed with the data. I'm trying trainer road simultaneously and most likely will donate to intervals ics instead
