I wouldnt recommend this to anyone anymore

The health bar prevents learning from happening which has been mentioned in many previous reviews. Regularly when I do practice lessons that should add to my health, the app failed to give me the addition to my health. Growing more and more disappointed with this app with every update, which is really sad cause I used to recommend it to everyone Id run into that even had the smallest desire to learn a language. Just really sad to see a great app fall apart

This was disappointing. about Duolingo Learn Many Languages for Free, v5.1.7
