IF refers to Illustrative Fortran. IF can also refer to the Android application software first used to distribute the contents of Illustrative Fortran and bearing the same name; first published in Uptodown on March 23, 2021. It can also refer to the web version, which is known as IFW. Both the app version and the web version are two current ways in which the contents of Illustrative Fortran (IF) are being distributed to users.

IFW is the web version of the Illustrative Fortran Android application software. It can be rendered an initialism with full meaning “Illustrative Fortran Web.” It has the same content as the Android app, may differ in user interface at some point, have a slightly different way of use compared to the app, may have features not in the app, or may lack features existing in the app. It first existed in the subdomain illustrative-fortran.atwebpages.com since June 2021, before the Illustrative Fortran official website www.illustrative-fortran.com was launched on March 21, 2022. Initially, its user interface was made specifically for devices with small screens, like Android smartphones, then later optimised to be compatible with large screen devices, like PCs.
