Key Features:
- Add notes and labels to any entry so you can remember what each entry represents.
- Variable value entries, so any time you have to reference a single variable more than once in a calculation, you can. And if the variable changes, you can change the variable value once and every instance of the variable is automatically updated.
- Every entry and calculation is completely editable so you dont have to start over if you need to make a change or if you need to correct a mistake!
- Branching calculations and entries allow you to make and link separate calculations and see every part by simply swiping to scroll back and forth or tapping an entry to step up and down through levels of your calculation.
- Currency mode makes money math simple and presents it to you rounded as you would expect. Switch back and forth to regular decimal mode without losing the additional accuracy of the extra decimal places.
- Save and Load calculations so you can keep important information or lists to refer to or edit later and make other calculations in the mean time!

NEW: Now use any saved calculation as a variable in another calculation. Want to use the result of one calculation in a new calculation? Save it and do just that!
