I tried that new app for tracking my workouts, but it feels so useless.

Really? What didn't you like about it?

It just doesn't give me any good insights; it seems pretty useless overall.

That's disappointing. I hate when apps promise so much but deliver so little.

Root Explanation
Useless → It is formed from "use" (from Old French *us*, meaning to employ or utilize) and "-less" (meaning without). The word "useless" means without use or not able to be employed effectively.
Memory Tip
Think of something that is 'without' ('-less') 'use' — that's why useless means it cannot be employed.
