Ratings and reviews

Better than the newer, flashier dictionary apps (hear that, MobiSystems?). The interface is simple yet highly functional, and searches take advantage of basic computing technology, i.e. they lead you not only to headwords but also to phrases and idioms containing your search term (hear that, MobiSystems?). Excellent!

I've used this app almost daily for a couple of years. When I tried to move it to my new Pixel 7, it said "incompatible". Ultralingua told me that they don't plan to recompile it for the 64-bit platform. I guess it's easier to abandon paying customers.

English/Spanish edition: great app; use it all the time and it rarely fails me. The only suggestion I would make is that I would love to be able to look up phrases as well. Strangely, my husband's newer version does do this but his one doesn't show the various uses of the word you look up, which mine does! Given that, I actually prefer my version but it would be great to have both. : )
