Grrr I should have read closer

I was on the website where they have English Spanish and German, so thought the app would have German. Nope, it doesn’t. Yes, it says that in the description. My bad. But still really annoying. I hoped that I could count on it being updated with German someday, but apparently the latest update was 2 years ago, so figuring it won’t. Dang it.
Update to add the animations of the voiceless stops and fricatives have voicing - “tuh” instead of “t” etc. This is terrible!! At least the videos are correct.

Not what is was Too Bad

I used this site in the past and purchased the app hoping it was going to be similar to the desk top version. While it offers more languages, I don’t care for the app version. Everything was on one page per sound on the desktop version. I could see both the animated and live model version. It provided a profile and head on view. So much better before. Now, I have to jump between various pages and in the process lose the students attention and just not as effective.

I will use it because I paid for it but may opt for other visuals

Needs improvement

I used to love this site because it would give you a list of words examples for each sound . Another downside of the app is that it doesn’t show you the sound for the complete word , rather it breaks it into parts but I want to be able to hear its pronunciation in both forms . As an English language student and linguistics student I find it a bit problematic not to have enough examples . Please make the app quality as good as your site . A big thanks though for all the good work you have already done .
