I use the old and might percentage calculators quite a lot. And I do believe that a few of them have great functionality, but they are ugly. Same as they were 20 years ago. So I have designed a better looking version with a few more features: - Dark theme - Theme auto load - based on OS - A single cookie to remember theme preferences for 1 year - Removed the "Calculate" button. All the math is done automatically. With a 0.75s delay to not feel like spamming results - Built-in copy mechanics for the result fields. One click / tap of the field and the result is in your clipboard - Auto separator for large numbers - probably one of the most common problems for all websites - Numerical Keyboard for mobile - Only 2 decimals, not 10 - Super fast loading - No google analytics * The 0.75s delay is there because it takes me about 1s to move the mouse from the last input field to the result. So this is what felt ok to me.
