iTunes Store Failing

I have the same negative review of this app as many others complaining of crashing, crashing after attempt to input a birthdate, etc. its astounding how many users are having the same crashing problem and Apple iTunes has not forced the developer to either FIX IT!! or remove the stupid non-working app from the store before subjecting more unsuspecting users to infinite misery with this app. Tried giving it no stars or a minus rating but in their wisdom I have to give it @ least a star or its not submitable
