How to Fix Duolingo Practice To Earn Hearts Greyed Out (January 2026)

Duolingo is one of the most popular language-learning apps with millions of users across the globe.

The popularity of the app lies in its gamified version of lessons that are quite addictive. 

However, many Duolingo users have been encountering the Duolingo Practice To Earn Hearts greyed-out issue lately.

If you are also a Duolingo user facing the Duolingo Practice To Earn Heart greyed-out issue then read on to know why. 

Duolingo is currently facing criticism from users across the world.

The reason behind the controversy is its latest update that has apparently removed heart feature for free users.  

Users could practice old lessons to regain their hearts after losing them to mistakes.

Now, they are left with options such as waiting for hearts to regenerate over time or paying for the premium version.

According to reports, Duolingo is testing the removal of the option to practice lessons to earn back hearts. 

Without any further ado, let’s get started:

What Are Hearts on Duolingo?

Hearts on Duolingo are like lifelines, a user will start with a maximum of 5 hearts and lose a heart for each mistake.

Duolingo uses a heart system to instill accuracy in language learning. 

Each mistake costs you a heart and if all the heart is lost, you will not be able to complete the lesson.

Users could regain hearts through practice exercises, watching ads, or spending gems and more.  

1. Practice Exercises

  • To restore a lost heart, practice previous material or lessons.  
  • Tap on the Hearts icon.

2. Watch ads

After completing a practice session, you will have a heart unlocked. You can then watch an ad to add some more hearts.
