There is no explanation for what "a credit" gets you? i.e. how are people supposed to know, when they are prompted to pay after the first 10 minute test, how credits are to be interpreted? I.e. is a credit 1 minute? is it 10 minutes?

This should be described on your app home page, or at the very least in your terms of service. I cannot find it anywhere.

Also, the content user license is unsettling - giving you irrevocable rights to the user's content throughout the world into perpetuity (including the right to transfer).

I would recommend that if your audience is entrepreneurs / experts / thought leaders / content creators, that you balance this language with some thought for the user's desire to protect their IP.
