Note Calculator is a text-based calculator. Sometimes, performing calculations involving multiple equations can be challenging with a basic calculator, right? Using an app like Excel might feel too cumbersome and heavy for such tasks. Now, with Note Calculator, there's no need to worry. Simply write down your equations as if you were jotting them in a notebook, and it will automatically calculate them for you. You don't need to remember your calculations and results either. Your work is saved as text, which can be stored as a file and shared with any program that supports text. It couldn't be easier! Additionally, it supports variables, enabling you to perform calculations similar to simple programming: a = 3 b = 2 c = a + b Is it hard to remember or input variables? With a simple touch, you can select variables from a list or easily add new ones. Plus, you can group variables using blocks, allowing for even more advanced calculations. Key Features: - Text-based calculator - Supports variables for more complex calculations with ease! - Saves all calculations and results to a file - Supports grouping with blocks (for advanced calculations) - Easily share calculations and results with other apps (Message, Whatsapp, KakaoTalk) - Show calculation results up to the current cursor position - Percentage calculation improvement (e.g. $100 - 25% = $75)
