When I visited the index page for the first time, it seemed more like a student learning vocabulary tool than a language learning tool. It is a language learning tool, but I realized the way that it is structured, it can also be used as a flashcard learning app. What I mean by that, is when creating flash decks, you can create a deck that translates from German to German, or English to English, and then have a quesiton on the "New Word" side, and the answer on the "Translation side". With that said, the idea of the service is understandable, but not really enforced.

Yes. That happens mostly to me during French. You learn a word, and after a while you forget it because you learn different words, and hadnt used that word in a while. The more space you put within the repetition, the more it sticks inside your head.

I would not. The main reason is because I would not recognize it as a language learning app in the first place. Anki is a designed tool for learning anything with flashcards. Duolingo a tool for learning languages. You are trying to be somewhere in between, but advertise the flashcard part more than the language learning part. Eg. maybe instead of saying "Build vocabulary that actually sticks", write something like "Learn languages, fast and fluently", and below explain how your approaching learning a language differently. Other than that I would use Duolingo as it has more features. LingoBolt needs a feature that sets it apart of the rest. Maybe a chat, where someone asks you a question on the language you are trying to learn and you have 3 flashcards to choose from for an answer.

Yes. The onboarding is something I cant complain about.

Personally no. But I would definitely see somebody that loves to learn languages need multiple flash cards.

Yes, it is obvious that you try to improve your vocabulary skills from a language, however I'd recommend making the target atleast more specific (eg. Learning a language). The How it Works section btw is wonderful, good job on that

I have heard of spaced repetition from my englisch teacher, and the way that it was implemented there is pretty good. Learned a few spanish words fairly quickly lol (Exito, Salido, El realidad)!

Duolingo 100%. LingoBolt does have cool stuff, I actually loved the auto-translation mode when making a card (by pressing shift). Features arent that unique that they get me to use that more than other dedicated apps though.

4.

Yeah, even without the onboarding it is understandable right of the bat.

5.

No, but that is because the Pro version does not give extra features, it just gives more of a feature. Maybe even restrict the AI translation mode to pro version only, cuz that one made me create my card pretty fast ngl.
