German/English app

Have you tried Google Translate? Seems to work fine for me, though I wouldn't try having a conversation with it. Speaking phrases into it or typing the words seems to work fine.

I use an iPad/iPhone app “iTranslate” It does many languages. It’s free but they are aggressive in trying to get one to purchase the fee app. Just hit the X in the pop-up box and you can continue to the free version. I particularly
Iike the audio feature to hear pronunciation.

I have an app called Speak and Translate where you can speak or write any language and it will translate to another language. It's free at the Apple App Store.

We used Google translate and it worked great!

Do you want a dictionary to translate words, or are you translating phrases?
For a dictionary I recommend: https://dict.leo.org/englisch-deutsch/ There is also an app, search for "Leo".
This is produced by the technical university of Munich and is very accurate and comprehensive, I use it at work for words I don't know.

If you are using any dictionary without some knowledge of the language, beware of the risks. one word in language A can have two meanings covered by two different words in language B. For example "ticket".
1) entrance ticket (museum etc.) (=Eintrittskarte)
2) transport ticket (bus/train) (=Fahrkarte)
3) Season ticket (for transport) (=Abo)
3) air ticket (=Flugschein)
4) penalty ticket (parking or speeding ticket) (=Bussezettel)

Thank you all! I may look at all of those. All sound good. I really appreciate the input.

Chris, in answer to your question, I'm usually looking for words because I took German in school many years ago. Thanks for all those tickets! They're useful. We had a Bussezettel once but hope not to need that term again!

You can use "Strafzettel" for the penalty parking ticket.
