Calvance is a calculation tool with an infinite canvas.

# Core Features and Advantages

• Free Input, Clear Logic

You can freely input calculation formulas on the canvas and easily rearrange their layout, allowing you to intuitively see the entire calculation process and the thinking behind it.

• Ditch Paper and Pen, Easy References

Calvance records all the formulas you input and makes it convenient to use previous results for new calculations, as well as establish references and links between numbers. You no longer need to calculate while recording intermediate results with paper and pen, nor do you need to memorize any numbers.

• Easy Editing, Real-time Updates

You can easily review and track calculation details, effortlessly edit formulas, modify values, or correct discovered errors. All changes update in real-time, letting you immediately see new results.

• Labels and Notes, Easy to Understand

You can also add labels to numbers, turning formulas into easily understandable sentences. You can also add separate text on the canvas for additional notes on the entire calculation, making it convenient for future review or sharing with others.

• Reuse Formulas, Quickly Test Different Scenarios

With Calvance, you can create complex calculations in an intuitive way, test different scenarios, and let numbers help you think. When you turn those important, complex calculations into a series of formulas and reuse them, you'll experience Calvance's efficiency and convenience.

• Better Than Paper and Pen, Simpler Than Spreadsheets

Using Calvance is like using paper and pen - you can write freely, but it helps you complete the heavy calculation work. It's also like using a spreadsheet with real-time updates, but more intuitive, saving you time on setting up rows and columns.
