Website feedback

If I already have a file with my speech, can I get feedback on it?

Can we have standard IPA or at least a switch to use IPA instead of the current system to indicate how a word sounds like?

Chat with Oliver doesn't work. I can't hear him, I can only read his texts. I can hear all speakers except Oliver.

On my page the overall score is shown as 94. I do not understand what it really means. Does it mean comparing a native speaker, my pronounciation is 94? It does not compare with other users, if I am among the ones who have improved from another point to this point? Since when I have improved my score? Who are the same like me? Am I among the 20% of learners on the website? Is anyone improving better? Am I like another person and I have improved better?

i choice the sloweest voice, but when i play the record, but It sounds like the fastest speed, so fastest speed is same to slowest speed. is a bug?

I tried to say some words intentionally incorrectly, and still got "Well said" feedback. I was saying literally gibberish

Are you planing on creating an App for Apple devices (ios or mac)?

I receive some emails from you. They are exciting challenges designed to help me practice speaking on topics that matter to me. When I click to the button I go to a special training window at my browser and start my exercise. I like the exercises. They worked well in the past but recently I started to experience the problems. The page stop working during the exercise. It happens sometimes during the introduction speech from the system sometimes it stopped working when I speak and other time on system respond to me when I listen the question from the system. I don't know if it's only my computer doesn't work or it's a common problem of the system. Please advise if it's my computer is anything I can do to fix it.
