Calvance is a canvas calculator that keeps every step of your calculations together, so you can see how the numbers connect, make changes, and pick up where you left off. Arrange formulas, numbers, and notes freely on a canvas. Use the result of one calculation in the next. Change an input and linked results update, without starting over. From material quotes and cost estimates to budgets across currencies, keep both the calculations and the thinking behind them. Change the inputs, not the whole plan Build a material quote with quantities, unit prices, and expenses on one canvas. Change a quantity and the linked costs and total update. When it’s time to revise the quote, your formulas and notes are still there. Connect formulas and adjust quantities, prices, or other assumptions to compare alternatives using the same calculations. See every step and remember why • Arrange formulas freely to see earlier and later steps together. • Label numbers so you know what each value represents. • Add notes about your assumptions, purpose, and methods, so your work still makes sense when you return. • Your calculations save automatically, ready for you to continue. Calculate with units and currencies Use length, weight, time, and currencies directly in your formulas, including compound units such as price per meter or cost per hour. Calculate costs from quantities and unit prices, with the meaning of each input and result clearly shown. Convert compatible units and calculate across currencies. Use converted results in the next formula, working from material quantities to costs and on to the total budget without handling conversions separately. Each canvas keeps its own reference exchange rates until you choose to update them. Return to a budget and continue using the same rates. Rates are for reference calculations, not live trading quotes. Reuse your work next time Start with a template or duplicate an existing canvas to use a familiar approach for a new task. Adjust the inputs without rebuilding your formulas. Organize projects on separate canvases. Export an image to share the steps along with the result, or export a canvas file to save or share the full calculation. Calculate your way • Follow your system’s number format or choose your own decimal and grouping separators, with support for Indian digit grouping and adjustable decimal places in results. • Work with an external keyboard, dark mode, and a Liquid Glass interface. • With Premium, sync your canvases across devices and continue on another device. Start free, upgrade when needed Core canvas calculation features are free. Local Pro and Local Unlimited are one-time purchases. Premium is a subscription that includes cross-device canvas sync. Assigning units or currencies to numbers requires Local Pro, Local Unlimited, or Premium. Calculations you can continue.
