### 3/5 — Close, but not quite there

*2020-11-11*

This app is the best I have seen yet at HIT / Body by Science training. The developers clearly designed a uncluttered app which differs from most workout apps and it makes it a pleasure to use. I love the simplicity. However, there are two or three simply features that would greatly improve the functionality without complicating the user interface. Unfortunately, there is no way to send suggestions and no contact info on their website.
