[1/5] They’ll charge you fraudulently

When you sign up, you will be led to believe that the subscription is managed through the App Store, and then the subscription will not show up in your App Store subscriptions. They claimed to notify you before the charge hits your card, they actually claim they’ll let you know twice, they do not do that. DECEPTIVE!

[3/5] Fun but what

Cool that I pay for yearly and still get constantly pestered in the app to spend more money. This is behavior I’d expect from a free app. We are all sick of this behavior, stop normalizing it, do better.

I’m Hispanic and didn’t learn Spanish growing up, I may just have a chance. Really grateful for this app and really hoping this helps.

[1/5] Scam app

Do not use. Many in-app glitches that take your money and take your timer boosts for in-app game play. You can follow instructions, provide evidence, screen recordings, photos. No one responds but an auto reply. Even for “Max” paid subscriptions. Its all AI. No humans working here. Glitchs in AI voice recognition make it impossible to finish game play and effect competitive game play negatively. I liken it to Candy Crush in app scams. There are no refunds. Read Reddit. I recommend Babel for your language app. This is just a useless no longer fun game.

[4/5] Really good

It does really good to teach you things quickly for free or at least for a cheap price, but the only problem that I see is that it teaches you things but it doesn’t make you understand them
