A calculator memo on a paper-style roll. Switch calculator and formula modes, edit rows, add notes, and export to PDF. Includes unit math and multiple calculators.
A calculator memo app with history that keeps your calculation process visible like a paper roll. Switch between calculator input and formula input to handle everything from everyday math to calculations you want to keep as records.
■ Calculator mode and Formula mode
Calculator mode evaluates left to right (5+5×2=20). Formula mode respects operator precedence (5+5×2=15) and supports parentheses and roots. Switch anytime from the input row, changing the calculation style without leaving the active input area.
■ Paper-roll style history
Expressions and answers stay on the roll from the top, so you can see the flow of your calculation at a glance. Subtle side lines and top shading keep each frame easy to distinguish, even with multiple rolls. In calculator mode, a running total can be shown while you type.
■ Edit rows and add notes
In calculator mode, tap any roll row to edit and recalculate. Add a note to any history entry. Swipe left to delete; swipe right to add a memo, copy the expression, or copy the answer.
■ PDF export
Export a calculation roll as a PDF whenever you want to keep it.
■ Use multiple calculators side by side
Up to a triple deck. Add or remove panels with the [+][−] header buttons, swipe or tap to switch, and double-tap to toggle between 1-panel and 2-panel views.
■ Unit-aware calculations
Calculate with units of length, area, volume, and weight.
■ Customizable keyboard
Long-press any key to define it, and merge keys vertically or horizontally to create larger keys. Switch between 5 layouts (30 keys each), and export or import your arrangement.
■ Flexible display settings
Choose the decimal point and grouping symbols, the grouping style (every 3 or 4 digits, Indian style), the number of decimal digits, and the rounding mode (including round half to even). Pick Auto, Light, or Dark appearance, and enlarge or reduce text size. Your settings are restored on next launch.
■ Beginner and Expert modes
Beginner mode shows labels and tips for each button. Once you are comfortable, Expert mode unlocks advanced operations such as long-press key editing.
The calculation engine uses C/C++ fixed-point decimal, stored internally in BCD arrays.
