If you want to learn German, get Duolingo. Its free, has over 2000 more words then this 400? word app. 400 is generous estimate. It felt like 200 words. App so lacking vocab and phrases that free is paying too much for it. Need interactive learning? Duolingo. Need verbs, shopping, sentences, grammar and so on? Duolingo. Rebotomy is WORTH the price if you can hear too. Its expensive but works like Rosetta Stone only better images. Holfeld apps do not have that functionality either. Not worth your time!
