The HP Prime Graphing Calculator is a graphing calculator introduced by Hewlett-Packard in 2013 and manufactured by HP Inc. until the licensees Moravia Consulting spol. s r.o. and Royal Consumer Information Products, Inc. took over the continued development, manufacturing, distribution, marketing and support in 2022. It was designed with features resembling those of smartphones, such as a full-color touchscreen display and a user interface centered around different applications. It claims to be the world's smallest and thinnest CAS-enabled calculator currently available.
The functionality of the HP Prime is also available as emulation software for PCs and Macs, as well as for various smartphones.
