Are there any duolingo-like (beginner friendly) apps to learn about cybersecurity?

I tried to search this subreddit but only found stuff about app security.

I know that if there is a duolingo-like app which teaches me stuff in 10-15 min chunks where I probably wont write code isn't the best thing, I just want to use to supplement courses and practice. So my question: do you know of any beginner-friendly apps (paid or free), which can teach basic concepts about cyber security?
