Interesting, it looks like this is an app geared at accent reduction, which could be promising. I'll try it out.

Duolingo French elicits speech, but I fear that it is set so permissive as to hardly be helpful (I haven't dared to test feeding it nonsense or clearly incorrect pronunciations yet). There's a Czech-learning app I use that uses speech recognition to test the user's pronunciation, but the implementation is bad: it is fairly strict, and the speech recognition simply tries to interpret the speech (rather than gauging correctness), so it frequently misinterprets the user's utterance as another statement entirely. Which is frustrating and unhelpful.

Making your accent absurdly french like in a cartoon fools Duolingo. I do it when I get too frustrated with the pronunciation and want a pass.
