Hey Product Hunt!
I built InstantCalc out of personal frustration every calculator site I used was either full of ads, required an account, or just felt slow on mobile.
So I built the one I always wanted: 6 essential tools (unit converter, age calculator, word counter, image compressor and more) that open instantly in any browser, run 100% client-side, and never ask for your email.
It's completely free and always will be. Would love your feedback what tools should I add next? 🚀
