Question(s) about the heart system.

Can someone explain to me the history of the heart system? I'm very new to the app.

And I'm not gonna lie, heart system is irritating. I'm a slow learner, and I want to re-review all the lesson(s) that I feel uncomfortable. But due to the heart system, I can't redo the past lessons I feel like I need to review again.

And is this post on the correct section of the board?

Thanks in advance, Ken

You do not have to use the "heart system". Just click at each single lesson.
And you can re-review every lesson as many times you want by clicking it again.

Is heart system only for the mobile users?

The heart system is appearing both in the App and the web version. It only appears in a lesson when you click at [Test out].
For more information see the unofficial Duolingo Wiki at

I find it very annoying too - could be a dealbreaker for me too. The point of learning is that you learn from your mistakes. If I make too many mistakes and get locked out that means that I can do three things - 1. Pay the required amount (NEVER) 2. Wait it out - it seems to restore itself after a few days (WHAT IS THE POINT OF THAT!) 3. Check all my answers on another app/dictionary so that I don't make mistakes (THAT WILL SURELY ENCOURAGE ME TO MOVE OFF DUOLINGO AND AGAIN - WHAT'S THE POINT DUOLINGO?) I know candy crush saga used to expect you to either pay or wait 3 days to move to another level. Guess what? They removed that feature. So wise up Duolingo. You have to make it fun and easy or people will give it up. I understand the necessity to make money out of the app but this one is a negative step if your intention is to teach language. People learn from their mistakes!

I've I've understood right, you can just do another strengthening lesson or two to get some health back, and then it will let you do new lessons.

This is a question about how to use the site, so it needs to be in troubleshooting.

Have a look at this official guide: In which forum should I post my discussion?.
