If I cannot get rid of the health bar, I will get rid of the app, leave duoLingo, and move on.
I really like the duoLingo app, but the health bar limits my access. I make a typo, lose a heath bar. Forget the correct form of pronoun, lose a heath bar. Miss hear a word, lose a heath bar. Brain-toot, lose a heath bar. Within minutes, I can't use the app for 24+ hours. My roommate has the non-heath bar version. I would like the same thing.
The app works...when I get to use it. I've learned and am excited to keep learning, but as soon as I hit a spot where I struggle, my opportunity to improve is taken away.
I will try to reinstall my app, but if that does not work, I will delete my account and move on, but not after letting as many people as possible know not to waste their time downloading the app.
