General Legal Research Apps

App is short for software application. Apps are designed to run on smartphones, tablet computers, and other mobile devices, not on desktops. They are usually obtained from the Apple App Store (for iOS mobile devices—iPads, iPhones, and sometimes iPod Touch), Google Play (for Android mobile devices—phones and tablets), or the Windows Phone Store. Sometimes there are also Apps for Blackberry devices. For each App listed below, we will indicate if it is currently available for iOS or Android devices. It’s always a good idea to go online and check to see if any of the iOS Apps we mention are now available for the Android and vice versa.

To search for and download legal research apps, locate the “App Store” icon on your device. You usually have to know the exact name of the App, so they are not that easy to find. To help you find useful Apps, we list a sampling by topic or practice area and have also listed sites and books where you can find more, such as:
