CalcNote is a revolutionary calculator app designed for smartphones. It allows you to jot down calculations in a notepad-like interface, and the results are computed and displayed instantly—eliminating the need for pressing the equal button. You can write multiple calculations at once, enabling you to see numerous problems and their answers simultaneously. Adjustments to any part of your calculations are possible at any time without the need to start over; simply correct the mistaken part, and a recalculation occurs automatically. Merging the advanced functionalities of spreadsheet software with the convenience of a calculator, CalcNote represents the next generation of calculator apps, making it a must-have tool for quick and efficient calculations.

[A Fusion of Calculator and Notepad]
With CalcNote, you can input calculations as if you're writing a note, and computations are performed automatically. Calculations are always displayed, making it easy to spot any mistakes. Furthermore, you can jot down notes alongside your calculations, enabling you to compute text-mixed expressions like the examples below:

Example:

Shop A
USD 18 * 2 items + USD 4 (shipping)

Shop B
USD 19 * 2 items (free shipping) + 8% (sales tax)

Shop C
USD 18.30 * 2 items + USD 5 (shipping) - USD 2 (point redemption)

By keeping calculations and notes together, the purpose of your computations becomes clear at a glance when reviewing them later. Calculations and results can be saved as files, printed, or sent via email using Android's share function.
