Hate calculating molar mass using a periodic table? Periodic automatically calculates the molar mass of selected elements on a periodic table. This makes the task of using molar masses in chemical calculations much quicker and easier.

Functionality:
- Simply tap an element once to add one atom to the compound. Tapping multiple times will add more of that element to the compound. For example, to input C2H3O2, tap Carbon twice, Oxygen twice, and Hydrogen three times.
- To remove an element from the compound, tap and drag down from the element.
- To entirely clear the current compound, swipe down with two fingers.
- To view your previous calculations, swipe left. To clear your history, click the X icon on the right of the screen. To close your history, swipe right.
- To view this tutorial with slick animations, click the question mark icon in the app.

Features:
- Instantly updates the mass with each newly added atom
- Includes an (almost) proper element organization function that orders the chemical formula from its element components
- Adds a notification badge on the icon for the mass calculated when the app closed. Good for multitasking when you need to quickly see the mass without opening the app.
- Records your previous calculations so that you don't need to keep entering them
