Literally no clue how to use this

I am testing out a bunch of workout apps and all of them seems to be designed super unfriendly. This one tops it off. The design looks appealing and cool and all at first. But once you try to figure out how to use the app, you might as well give up. Like I had to spend a minute before I just have up on starting a workout and entering my sets and reps. Also if you havent noticed the invisible info button at the top which almost hides in the background, you will never find the page which lets you leave a review satin how bad the design is and should be used for game design instead of a workout utility app. Cant believe I have spent money on this.
