# An alternative to SpeedCrunch and Qalculate Written 18 October 2026 by Adrian Viziteu. SpeedCrunch and Qalculate details are from their own sites; both are free and open source. SpeedCrunch and Qalculate are excellent free calculators: you type an expression, press Enter, and it goes into a history. Ratio works like a note instead: every line stays editable, can be named and reused, and the whole sheet recalculates as you type. | | Ratio | SpeedCrunch | Qalculate! | | --- | --- | --- | --- | | Price | $9.99 once, 7-day trial | Free, open source | Free, open source | | Platforms | Linux, Windows, Mac | Linux, Windows, Mac | Linux, Windows and others | | How you work | A sheet of lines that all stay live | One expression at a time, with history | One expression at a time, with history | | Live currencies | Yes, 160+ plus crypto | No | Yes | | Units | 150+ | Some | Very many | | Dates, time zones, working days | Yes | No | Dates, yes | | VAT, loans, margins in plain words | Yes | No | No | | Symbolic algebra | Equations and exact answers | No | Yes, much deeper | ## The same work as a sheet Instead of a history you scroll back through, a Ratio sheet keeps the steps. Change the first line and everything below updates. | price = 1200 | 1,200 | | --- | --- | | discount = 15% | 15% | | price - discount | 1,020 | | L3 * 2 | 2,040 | | prev / 4 | 510 | | 255 in hex | 0xFF | | 0xF0 & 0x3C | 0x30 | | 1920x1080 aspect | 16:9 | ## Choose Ratio if Your sums are a few connected steps (a budget, an invoice with VAT, a trip in another currency, a deadline in working days) and you want them in one editable page instead of a history. ## Choose SpeedCrunch or Qalculate if You want free, open-source software, need Qalculate's symbolic algebra and huge unit list, or mostly type one quick expression at a time.
