What Numa does
Plan a trip on one canvas: flights, nights, daily budget. Change the number of nights and every total, link and graph follows instantly.
Numa is a calculator for iPhone and iPad where every calculation stays on the canvas like a note. Change a number and every result updates instantly.
A CANVAS, NOT A DISPLAY Calculations sit freely on a canvas that grows with you. Nothing disappears after the equals sign: tap a number, change it, and everything that depends on it is right again.
LINKED VALUES Select a result and press an operator: a linked number appears below it in its own color. Or drag one number onto another. Changes flow through as many steps as you like.
CALCULATE WITH NAMES Label a number, say “Rent”, and keep calculating with the name: Rent × 12. A canvas reads like a page of notes and works like a spreadsheet.
SCENARIOS Give a number up to three values (A, B, C). Numa works through every scenario and shows the results side by side.
Sliders and graphs
- A slider on any number, smooth or in whole numbers
- Graphs: a number becomes x, its result the curve. Several curves, live
On iPad too
