Hi Product Hunt community! 👋
I'm excited to introduce Opal Calculator!
I built Opal Calculator because everyday calculations shouldn't require opening multiple websites or dealing with cluttered, ad-heavy tools.
It brings together free calculators for math, percentages, home projects, business, food, and more in one simple place.
I'd love for you to explore it and share your honest feedback.
What's one calculator or feature you'd like to see added next?
Thanks for checking it out! 🚀
