pretty good so far, i like it !! however, there are some weird glitches. I had echo fluency off and got the example sentence, 3にん人がいた and i said that exact phrase (san-nin hito ga ita). HOWEVER, it was marked wrong because the app registered "san" as being a half-width three (3) and not the full width one given in the sentence (3). thank god you can proceed anyway, but it was confusing lmao. thanks for the app, though! itd be cool if we could use our own sentences maybe in the future.

Thank you for bringing the numbers bug to my attention; I'll work on fixing that as soon as possible. Regarding using your own content, that's definitely on the roadmap.

This is one of the best speech practice tools I've used. I wish there was a way to pay a few dollars to remove the non-intrusive ads at the bottom. It's not perfect, and there are some TTS that don't work perfectly, Occasional crashes. But it's definitely worth checking out!

A really wonderful app for improving Japanese pronunciation and speaking confidence. As a beginner Fluency Tool is more approachable than Aomi, and more thoughtfully structured than Glossika - with the sentence length and difficulty much less daunting. The immediate feedback is really useful for fine-tuning pronunciation. It's good to hear straight away what sounds good, and what needs a little more practise. The feedback brings fast improvement. A fantastic edition to my 日本語 toolkit!
