Hey Product Hunt Community! Meet Opal Calculator – Your All-in-One Everyday Math & Utility Hub
Hey everyone! 👋
I'm super excited to share Opal Calculator with this amazing community!
As developers and everyday internet users, we often find ourselves opening 10 different tabs just to calculate percentage drops, cubic yards, tax estimates, or simple daily metrics. I got tired of messy, ad-heavy tool sites, so I built Opal Calculator to solve this.
It's a fast, clean, and distraction-free hub packed with accurate online calculators for math, home, business, food, and more—all built on a modern, lightning-fast tech stack.
🚀 What’s inside?
Math & Percentage Tools (Decrease, Backwards, Mass percentages, etc.)
Home & Construction (Cubic Yard, Garden size, Home addition costs, etc.)
Business & Tax (LLC & S-Corp cost estimators, etc.)
Food & Lifestyle (Calorie counters, pet age calculators, and more!)
We are officially launching soon, and I would love to hear from you:
Which calculator do you use the most in your daily workflow or routine?
Are there any specific utility tools you wish existed online that we should build next?
