rofi-calc is awesome. It’s so convenient to just press a keyboard shortcut you have defined and instantly being able to type or paste your equation, no having to wait for a complicated GUI to load, no clicking required. You can just pop it in whenever you need. Also it does unit conversions, instead of a math equation you can just type 10 inches to cm or 10 eur to usd or 100 celsius to fahrenheit or 100 to binary which is a huge time saver.

Besides, it’s rofi and rofi rules 😎

Data can’t be deleted

The developer doesn’t provide a way for you to request that your data be deleted

Not big fans of the GDRP I assume 😂
