现代汉语词典 seems to be the de facto standard for Chinese dictionaries. Some users here use it as well. But it seems only possible for the paper version.
But I might miss something. Is it possible to use it outside of its paper version, such as online or app? I searched for it on the App Store, but seems that there are too many results and I don't know which is the correct one (actually all of them don't seem to be official ones...). Also I really hate it if I purchase an app but later found some words are missing.
Or is it only available on the paper-version?
