FAQ
Frequently
Frequently
asked questions
Is there a Soulver or Numi-style calculator for Windows?
Yes. Ratio works the same way, plain text lines with the answer beside each one, and runs on Windows 10 and 11. See Ratio as a Soulver alternative.
Does Ratio for Windows work offline?
Yes. Everything is calculated on your PC. Exchange rates need a connection to refresh, and offline Ratio uses the last rates it downloaded.
Is it the same app as on the Mac?
It uses the same calculation engine, so every line gives the same answer. iCloud sync, sharing a sheet as an image or link, version history, import and export, Liquid Glass and the ratio Terminal command are Mac only for now.
Can I use one license on Windows and on a Mac?
Yes. A 2- or 3-computer license can mix Windows, Linux and Mac. To move a license, click “Deactivate this PC” in Ratio Pro and enter the key on the other computer.
