For an English speaker learning Deutsch requires few apps to be used for translation, grammar, vocabulary. I am using few apps which helps in my learning.
I got to know about this app from a Deutsch Akademie staff who did the preliminary tests before joining the course. I use this app to translate English words to German. The beauty of this app is that it gives a lot of sample sentences. I referred this to a batch mate and she likes it very much.
Our instructor has provided this to us to refer to any Deutsch word for its meaning and grammar. Recently I asked a question about the deklination for the adjective rosa. My instructor mentioned that it is rosa only for any case and any gender. On checking duden.de it is mentioned as “indeklinables Adjektiv”.

I use this website http://www.online-translator.com/ and the corresponding mobile app to translate unknown sentences. You can scan images with Deutsch words or you can speak in the mike in the mobile app to translate it to English.
I mostly do not use this often. But for translating PDF documents from Deutsch to English this is far better than nothing. It provided similar features like PROMT. Both PROMT and Google Translator are free apps.
When I was learning ice skating in Kagran I came to know about an app for improving vocabulary on a daily basis through a friend. This is the website https://www.languagecourse.net/. There is a mobile app too which I use mostly during commuting. This is very effective indeed.
When I wanted to check the conjugation for the verbs I came across this website http://conjugator.reverso.net/conjugation-german.html. When I downloaded the corresponding app i started loving it. The killer feature of this app for me is that you can listen to the sample sentences in both Deutsch and English. You can upgrade to a Premium version with a cost which would make the app advertisement free, provide you a way to learn and remember your search results for a longer period of time.
I started my Deutsch learning with this cool app. This is a very popular app for learning Deutsch, at least to get started. I love the flash cards too.
There are a quite a number of accounts who share Deutsch things to ease the learning. Just search for the word Deutsch and/or German and you will find lot of them to follow.
I find this very interesting with pictures. You will get suggestions based on your history of the searching.
There are a number of Youtube channels through which you can learn German. I personally like “German with Anja” and “German with Jenny” a lot. I am a patron of both of them ! There are many other channels too like “Learn German”, “Learn German with GermanPod101.com” and so on. Once you are in a channel you can look for related channels and sky is the limit !
If you buy the books from Hueber https://www.hueber.de/menschen you can use this app to scan the pages to listen to the audio of that exercise. Usually it makes sense to use this app if you practice exercises with Hueber books. The books will provide CD, DVD for both course book and exercise book. But on the go, you can easily use this app without having to carry CD, DVD everywhere.
And last but not the least the free app from Deutsch Akademie itself. You can practice a lot of grammar and exercises.
