Any advice for a busy professional doing 20 minutes a day?

I have a chaotic work schedule and can only squeeze in 20 minutes of Ukrainian daily. I’m tired of bouncing between four different apps that don't seem to connect to each other. I want to spend my limited time actually speaking. Should I just commit to using Chickytutor.com for a solid 20-minute verbal session each day instead of trying to juggle grammar exercises and vocabulary flashcards?
