Well done dictionary app. I use it all the time and being able to check conjugations on the fly is very useful for beginners. My only issue is sometimes when I search the sesrch screen will go away and instead of showing me the results it'll show me another search screen with my previous search. Hopefully that bug gets fixed soon but it's still great. It helped me a lot in my study abroad to germany.

Sorry, we can't reproduce the error you're seeing, it seems like you are being redirected to the "History of search terms" page. which should only happen if you tap on "View search history". Can you find any pattern that might help us repeat this issue? Feel free to contact us via e-mail ( android@leo.org ) if you want to attach screenshots.

I use this app everyday multiple times for my English teaching. I love that it often provides a range of field specific answers and parts of speech. For example, same word where possible as a noun, verb, adjective and some context. The only thing is it only allows one word searches. German has many collocations whereas in English it's two or three words, which are not possible to search together. Otherwise a fantastic app.

Thank you for your super super useful and practical dictionary , i really enjoy using it but i just have a problem , right below the search bar is the part that you got to choose the language you want to translate, can you please move it to the upper part of the screen ? It's often happened that i want to rouch the search bar but instead it goes to the list of languages and it's a bit annoying, beside that it is a great app
