Siffra is a beautiful, lightweight, fast, and accurate calculator with support for dimensional analysis. The project is currently in heavy development, and is not currently stable yet. However, it is usable.
There are provided prebuilt binaries for all supported platforms in the Releases tab.
To build Siffra from source, you will need to have the following installed:
Once you have these installed, you can clone the repository and build Siffra with the following commands:
bun install
bun run tauri buildYou will find the built binary in the src-tauri/target/release/bundle directory.
note: Siffra currently only officially supports macOS due to testing limitations, but I am working on adding support for Linux and Windows. Please open an issue if you have any problems running Siffra on your platform.

Because Siffra is still under heavy development, I am not currently accepting contributions. However, once the project is more stable, I will be accepting contributions. Please do, however, feel free to open an issue if you find a bug or have a feature request.
Unlike other calculators that provide similar functionality, Siffra is open-source, which also means I am unable to make a profit off of it. If you would like to support my future work, you can do so by buying me a coffee using the button below. Thank you!
