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.
