I recently got into nocode and came across an interesting stack. Decided to launch a stock options calculator. The current available solutions are either inaccurate or provide a poor user experience because of ads. So I present to you OptionsCalculator.io an accurate ad-free solution. Any feedback would be super appreciated!
Congrats & Thanks for making it ad-free.
It's very clean and simple.
Have you considered about adding an quantity option. ( i.e. number of shares )
And if you make it a PWA then android user can save it as an app on their home screen.
It looks really good.
