Reference guide for APA 7th edition - Short version

Short version of the reference guide for APA 7th edition, a guide intended for students at the departments of Biology and Environmental Science at Lund University on how to format references according to the APA style.

Software and apps

Software and apps

Common computer software, mobile apps and programming language mentioned in the text, but not paraphrased or quoted, do not need citations. If the program/app is relevant to mention, simply give the proper name of the software or app together with the version number in the text. What counts as common depends on the intended reader of the text and whether or not they can be expected to know about the software/app. Software or apps that do not need citations include for example Microsoft Office (e.g. Word, Excel, PowerPoint), social media apps (e.g. Facebook, Instagram, Facebook), survey software (e.g. Qualtrics, Survey Monkey), Adobe products (e.g. Adobe reader, Photoshop, Adobe Acrobat), Java, and statistical programs (e.g. R, SPSS, SAS).

However, if you paraphrase or quote a computer software or mobile app, or if you suspect that your readers might be unfamiliar with the software/app you are using, you need to provide a reference according to the instructions below. Some software/apps will have a group creator, e.g. a company, instead of a personal creator. If the creator is the same as the publisher, omit the publisher from the reference. 


Creator, A. A., Creator, B. B., & Creator, C. C. (YYYY). Title of work (Version #) [Computer software]. Publisher. URL

Creator, A. A., Creator, B. B., & Creator, C. C. (YYYY). Title of work (Version #) [Mobile app]. Publisher. URL
