PocketChem is a portable and user-friendly periodic table and chemistry reference app designed for iOS devices. It offers a clean and elegant interface with color-coded periodic tables in light and dark modes. Users can easily navigate through elements using the search feature and list view. Detailed information on all 118 elements is provided, including atomic mass, density, electronegativity, and more. Additionally, users can explore each element's history, uses, isotopes, and even flame colors.

The app also features handy chemistry widgets like a chemical equation balancer and empirical formula solver. Users can access reference tools for formulas, solubility rules, reaction types, and common chemistry constants. Moreover, the in-app database allows users to search for chemical compounds and provides links for further information if needed. For added convenience, there is even an Apple Watch app available for quick access to element information.
