This app works OK the first time you open it after downloading. The next time you use it, it either freezes as soon as you click on a lesson or works for a minute or so and then crashes. The only solution is to delete it, then download it again and start all over. It has been like this for many months now, through multiple updates, and the developer is evidently unable or unwilling to correct the problem(s). A further issue may be that ILL is now attempting to cover too many languages. They have assured me that they release new lessons weekly, yet the upper intermediate and advanced Japanese content seems not to have been augmented or updated in any meaningful way for years. What's there is not terrible, but it isn't great, either – and there's very little of it. In any case, if you're interested in learning a language, rather than wasting your time downloading the same app over and over, you should look elsewhere! (If you're wondering, the only reason I'm still attempting to use this terrible product is that I stupidly purchased a two-year membership, and the app stopped working about nine months in.)
I'm very sorry for the issues you're continuing to have with the app. To some of your points: (1) I'm not sure what part of our content you're looking at, but we release new lessons weekly. (2) While yes, it is an option to developers to reset past ratings when a new update is released, we've never done this. And we never will. While not perfect, we do have a very long rating history of people who have been very happy with the app. It would be foolish for us to wipe all of that out just to try to hide the occasional negative review from people who've unfortunately run into serious problems with the app. (3) There are unfortunately some known issues in v3.2 that were not caught before release that will be fixed in v3.2.1 which is coming very soon. At any rate, if you'll contact us at app@innovativelanguage.com we can try to help address all of your concerns.
