Bring units and currencies into every calculation. Link quantities, prices, and conversions on one canvas, then change an input to update the results.
Bring units and currencies into every calculation.
Calvance is a canvas calculator that keeps numbers, units, currencies, formulas, and notes together. From material costs to budgets in different currencies, connect each step, adjust assumptions, compare results, and keep your reasoning.
Connect quantities, prices, and costs
Use length, weight, time, and currencies in your calculations. Compound units such as price per meter or cost per hour make the meaning of each input and result clear.
Make conversions part of the calculation
Convert compatible units and calculate across currencies. Use a converted result in the next formula to work from quantities to costs and on to the total budget.
Change an input, update linked results
Connect formulas through references. Adjust a quantity, price, or other condition and the related results recalculate, so you can compare alternatives using the same work.
Keep exchange rates with each canvas
Each canvas retains its reference exchange rates until you choose to update them. Return to a budget and continue with the same basis. Rates are for reference calculations, not live trading quotes.
Keep the process and the reasoning
• Arrange formulas freely and see earlier and later steps together.
• Label numbers and add notes about assumptions and purpose.
• Calculations save automatically, ready for you to continue.
• Start with a template or duplicate a canvas to reuse your approach.
Calculate your way
• Number formats: follow your system settings or choose decimal and grouping separators. Supports Indian digit grouping and adjustable result precision.
• Multiple canvases: organize calculations by project or purpose.
• Image and file export: share your calculations or save and pass along canvas files.
• External keyboards, dark mode, and a Liquid Glass interface.
• Cross-device canvas sync: with Premium, sign in with Apple, Google, or email to 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. Unit and currency settings are included in Local Pro, Local Unlimited, and Premium.
Calculations you can continue.

First, let’s be real, this app is a copy of Tydlig. Which is a calculator app that’s been around for years here (but hasn’t been updated in years. Still works great though). This app does include a few small new features, and the app works well, but unfortunately I can’t justify paying a recurring subscription for what I get from a one time purchase of Tydlig. If this was a one-time purchase… $5-7 or something like that, I’d buy it. But there’s no way I’d pay subscription for this. In fact, I suspect this app isn’t gonna take off if they keep this subscription model. Who’s gonna pay a subscription for this except professionals who do constant calculations, and those people generally already have more advanced tools for what they do, so I don’t see them paying for it either. I think the only target you can hit is the average user who needs it regularly but not frequently, and that user isn’t gonna wanna pay a subscription. (And again, this app is literally a clone of Tydlig with a few bells n whistles).If you change it to one time purchase, I’d prob buy it. It works well.
Developer Response
Thanks again for the thoughtful feedback. Based on feedback like yours, Calvance now offers two one-time purchase options—Local Pro and Local Unlimited—for local use. Premium subscriptions remain available for ongoing services such as multi-device sync. We appreciate your help in shaping a more flexible purchase model.
