Misunderstandings and subjunctive

I like hearing the correct pronunciation of words and the quick translation, but it often misunderstands significant words Im saying in English (and I CLEARLY know how to pronounce those!)! And, no matter how hard I try, I CANNOT get it to use the subjunctive tense! Introductory phrases like "its absolutely necessary that you..." or "Im very afraid that he..." which should absolutely introduce a verb in its subjunctive form NEVER work!!! This app is not alone; google translate doesnt generally do it either! Why havent they corrected this? Its a major mistake for anyone wanting to speak/write correctly!
