Doesn’t work and isn’t free

So disappointing. It wouldn’t move past the 1st question on any of the categories. It said I answered correctly, but when I clicked continue it just sat there. It also appears to be a paid app, not just a purchase within the app. It supposedly offers a 3 day free, but even that isn’t made clear upfront, and like I said, I didn’t even get that. I really wish Apple would require app developers to be more transparent upfront. Free should mean completely free to the user with the developers earning money through ads. Purchase within the app should indicate an app that is mostly free to use, but which offers additional options for a fee. An app that offers a free trial or a “lite” version is neither of these. It’s an app that costs money to use, and it should say that upfront. Do these shady practices really work in getting more users? Personally, I find it aggravating, not to mention deceitful, and I will always delete an app that does this.

Thank you

I can’t believe that I am learning vocabulary very fast. Also, I could solve many problems which I had with grammar and every part of the English language. Although I ’ve started to learn since around 2 weeks ago, I’m sure that this is everything that I need. I just wanted to say thank you so much🙏🙏🙏🙏
