The previous negative reviews must have been for an older version. I found this on AppGratis, and have been playing with it all morning, and noticed none of the impaired functions described in the review.
If youre looking for an app that explains French cooking techniques, this isnt it. However, if like me, you are a bit of an adventurous eater, this will help you get a handle on what that dish you just ordered is supposed to be, instead of assuming the kitchen gets it right. If I had something like this years ago, I probably wouldnt have waited so long to try veal caponata again.
