How the workout its shown to the client, or to coaches for offline clients, is a terrible experience.
It is too old, not pleasant to the eyes, just ugly.
If this make sense, I mean the screen when you add kilos and repetition. If this improves, the app would gain so much!
I would say is (for me) the biggest point at the moment.

all the rest is great. this stays for me the best app on the market. but just such a pity for the aesthetic that is honesty terrible.
