APP IS GREAT! I highly recommend it to any and all law students and attorneys. I only regret not giving it a chance sooner. ### 1/5 — Define “Woman” *2022-07-26* I actually had a good laugh over this. You have a legal definition for “Man” but you don’t have one for “Woman.” So basically for all the information you have your basically saying the professional by the book lawyer does not know what a woman is. Yet you have womens bureau and womens suffrage etc. So many things for this one type of person you can’t define. DO YOU HAVE ANY IDEA HOW STUPID THAT LOOKS? Sorry but for all your helpful information, you’re getting one star for that loophole. If you have any pride at all, get that fixed. ### 4/5 — From Law School to Lawyer *2022-01-22* I found the Black’s Law Dictionary application as a 1L student. The app was an incredibly useful reference for new words, Latin phrases, abbreviations, and important documents. As a practicing attorney, I use it as a reference when writing briefs, when providing additional specificity to certain terms for clients, or to simply understand when other lawyers are trying to be sneaky when using outdated language.(i.e., what is a cognovit judgment?). As some other reviewers have pointed out, there is room for minor improvements to the app interface and functionality, but overall, it works and it is a reliable. Despite these other minor issues, I would give this app a 5 star review, but there has always been one issue that bothers me when using this app: if I have audio playing in a different application and switch to Black’s, the app causes the volume to lower slightly. I’m not sure if this was intended, as though perhaps we need slightly more focus when looking up a legal term and therefore the volume should be lowered? Nevertheless, this little feature, whether intended or not, has always bothered me. Other than that, it’s a wonderful app and I highly recommend it. ### 5/5 — Excellent but where is the latest version *2021-09-03* I’ve taught law at the college level for several years This is an excellent tool to look reliable definitions of legal term at a more that 50% discount over the hard cover version. I’ve warned students not to look up legal definitions on the internet because who knows what you get. Blacks is the industry standard. There is really no substitute. I’d be happy to pay $60 for an updated version rather twice as much for an updated version of the hard cover ### 5/5 — 很好的一部英美法词典 *2021-01-18* 很不错 发音和解释都很全面准确 ### 5/5 — Excellent!!! *2020-12-05* Excellent!!! From Brazil. ### 5/5 — Лучший словарь!! *2020-09-23* Все мы тут от Тарасовой. Не пропускайте ее пары))) ### 2/5 — Try the free “Legal” dictionary app first *2020-04-06* This dictionary is overpriced. I suggest trying the free “Legal” dictionary first and if it does not meet your needs then download Black’s. I’ve been comparing definitions between the two and I am finding that the free dictionary provides similar and often more helpful definitions. Unlike the free app, Black’s is not always great at providing examples. ### 1/5 — iPhone X *2020-03-22* Адаптируйте под iPhone X ### 4/5 — 如何发音？ *2019-11-04* 如题。有没有设置可解决这个问题？ ## Frequently asked questions about Black’s Law Dictionary 10th Ed ### What is the price of Black's Law Dictionary 10th Ed?
