  • Not Optimized for iPhone X

    By dNelson_
    The content is great and I feel the app is well designed. But much of the screen on the top and bottom is just black and therefore is not used for content. Were this fixed, the reading experience would be far superior.
  • Huge missed opportunity

    By sangyeij
    This app is a massive missed opportunity. A mobile version of Black's could be indispensable for lawyers and students and easily justify the asking price. This app has not been updated to meet basic expectations (like iPhone X support), and more importantly it lacks vital functionality like generating BB citations or even just giving citable page numbers. As a student, $60 is a significant amount to spend on an app. I wouldn't regret it if the app met such modest expectations, but it does not.
  • Money grab

    By azoem
    I had the 9th edition app, which has been just as expensive, but they just disabled it. Instead of offering an upgrade at a reasonable price, they just put this one out. At full price even for those of us who had the previous version.

    You charge over $50 for this app. It is nothing more than a digital version of the dictionary. You get this price because law students pay exorbitant prices for every other book that they buy anyways. Update it for the iPhone X, so that I can ACTUALLY SEE what I paid for.
  • Needs to have page numbers

    By Husher1823
    I’m physically disabled, and unable to use the print version. Citations require you to include page numbers. I’ll revise my review if page numbers are re-added.
  • Bring back page numbers

    By One star as promised
    I agree with all the others that page numbers need to be included for each definition like in the 9th edition. It is impossible to cite without the page number. I will revise my rating once this has been done.
  • App needs updating!

    By L1 Law Student
    Great app because it keeps me from lugging around a huge dictionary however the app does not support the split screen functionality of iOS 11 which is a huge let down and inter-fears with some of my study habits 😒 Please fix this issue as soon as possible. I would love to give this app a 5 star rating.
  • Good Try, But...

    By ashenol
    So what you have here is simple enough- a digital version of the already indispensable Black's Law Dictionary. Functions with ease- searches are a snap, and often feature links to related or alternative terms. The pronunciation guide is exceptionally useful. All said and done, you've got a near five star app that's missing a few features- unfortunately most of them are rather severe oversights for a professional, especially considering this app comes with a $55 price tag. • The app possesses absolutely no ability to adjust brightness in app. In darker settings, this app is blindingly white. Most reading oriented apps (Kindle, Nook, iBooks) have long since included such a feature. • Physical page numbers for definitions, while not necessary, would be extremely useful for citation. • One piece of extremely crucial information that is omitted from the Black's Law Dictionary product line as a whole, but which could have easily been implemented here is which volume of Black's a given definition originates from. • The app doesn't synch bookmarks and history across devices. Not the most pressing issue, but it would have been helpful. • On a side note, the app icon is atrocious.
  • Great Resource but Needs Improvement

    By TayKens
    As a 1L, this app is a necessary tool. I like the convenience of not having to carry around yet another heavy book. I tried to get by with my Black's pocket dictionary but it just wasn't cutting it. When on my computer, it is easy enough to use Black's Law Dictionary via Westlaw. The app comes in handy when I am reading casebooks and not sitting in front of my Mac. I have to agree with another reviewer who mentioned that it would be great to have the page numbers included so that we can easily cite to it. That would definitely add to the value of this app as it is already the most money I have ever spent on a single app.
  • Wonderful!

    Easy to use, a great upgrade over the 9th edition app.
