I was in Japan last November. I did my best talking as much as possible, but especially in crowded environments my brain just stopped working and I had trouble saying even some of the most basic things
I never really focussed on talking. I started learning Japanese mostly because I wanted to read Japanese books and visual novels. But in Japan I learned that I really need to practice talking a lot more.
There are apps like Italki, but I found paying for those lessons pretty expensive. In Japan I read some positive things about that Chicky app. If I can remember correctly it’s free but very limited how much you can use it per day. At that moment there was a BF sale for it so I took a yearly subscription without testing the app a lot.
I’m probably the only one who never used DuoLingo so I can’t compare it with that 
The idea of the app is that you select your level, the AI comes up with the topics, remembers how well you are doing on certain grammar points and decided if some topics need to be repeated.
There is a progress overview, in which you can see a report of what was discussed, how it went and what the AI will discuss in the next lesson.
It’s absolutely terrible if you want to learn pronounciation, AI doesn’t work for that, but I find it superhelpfull that it first asks to say a short sentence, then builds it up to a bigger sentence with more grammar. Now I don’t have the real life stress of a busy shop with people waiting behind me and I can just take the time to think first about how the sentence should be.
I use it for a month or so now and notice that I don’t have to think as much anymore before I can say a longer sentence, so that’s great.
But - the app is superbeta, with lots of issues. That progress I was talking about doesn’t work in practice, It very often repeats the same questions over and over again. You can at any time change the subject and grammar point, but in my experience the whole progress system doesn’t work at all.
What I do is pick a grammar point from Bunpro which I’m struggling with, then keep practicing sentences with that.
The AI itself is pretty good, I’m not sure which engine it’s using. But - also here many issues. Sometimes I give the correct answer, it says it’s wrong, then gives me the exact same answer. It’s not a speech recognistion issue, it does the same answer when I type an answer. Also often the AI just stops talking halfway.
The dev isn’t responsive - I mailed my issues almost 2 months ago, didn’t get a reply. There is a forum on Chicky where people post the same issues but almost no activity there from the dev.
In short, despite all the issues I keep using it because simply practicing speaking helps me a lot. I have a Japanese friend on HelloTalk and until 2 months ago we only chatted, but now we start to talk more and more, mostly because I’m now more confident with talking.
Would I recommend paying for it - absolutely not, it’s a broken mess.
What I was curious about if others here are using it and maybe found a better way of using it, encounter the same issues or figured out ways to bypass those issues. Or maybe know of a better alternative to practice speaking solo.
