Stop typing. Start speaking. 4x faster.

Hey Product Hunt! 👋 I built MindSnap because I was tired of calculator sites that bombard you with ads, ask you to sign up, or make you scroll past 1,500 words of SEO fluff just to get a number. So I made the opposite — 35+ free health and productivity calculators that just work. BMI, sleep cycles, calorie intake, TDEE, and more. No account. No ads. No nonsense. A few things I'm genuinely proud of: → Every tool loads in under a second → Works perfectly on mobile → Each calculator includes a proper explanation of the formula, not just the result Would love your honest feedback — what calculators are you missing? What would make this more useful for you? I read every comment and the best suggestions go straight onto the roadmap. 🙏

I'm the maker of MindSnap a free collection of health and productivity calculators (BMI, sleep cycles, TDEE, calorie intake, and 30+ more).

I'm actively building new tools and I want to build what people actually need not just what I think they need.

So I'll ask directly: what's a calculator or tool you find yourself Googling regularly, but the results are always either broken, ad-heavy, or buried under a wall of text?

Drop it below. The most-requested ones go straight onto the roadmap.
