Smaller app mobile devices such as [[personal digital assistant]]s (PDAs) and [[smartphone]]s typically use the WIMP elements with different unifying metaphors, due to constraints in space and available input devices. Applications for which WIMP is not well suited may use newer [[interaction technique]]s, collectively termed ''[[post-WIMP]]'' UIs.<ref>{{cite journal | url=https://doi.org/10.1109/38.814559 | doi=10.1109/38.814559 | title=Beyond WIMP | year=2000 | last1=Van Dam | first1=A. | journal=IEEE Computer Graphics and Applications | volume=20 | pages=50–51 | url-access=subscription }}</ref>

As of 2011, some touchscreen-based operating systems such as Apple's [[iOS]] ([[iPhone]]) and [[Android (operating system)|Android]] use the class of GUIs named post-WIMP. These support styles of interaction using more than one finger in contact with a display, which allows actions such as pinching and rotating, which are unsupported by one pointer and mouse.<ref>[https://www.cs.tufts.edu/~jacob/papers/chi08.pdf "Reality-Based Interaction: A Framework for Post-WIMP Interfaces".]</ref>
