What kind of math calculator/tool do you wish existed but can't find online?
Hey everyone — I’m working on a personal side project where I build free calculators for everyday and academic use. It started as a hobby (I'm a solo dev), but now I’m trying to make something genuinely useful for students, researchers, teachers, and curious minds alike. I’ve already made tools like a Perfect Egg Boiling Calculator (yes, seriously), due date predictors, finance tools, and statistical calculators — but now I’m wondering: What’s a specific type of math calculator you wish existed? Something too obscure or niche for mainstream sites like WolframAlpha or Desmos? Maybe a calculator that automates a repetitive step in a bigger problem? Or a tool that helps visualize something you always had trouble wrapping your head around? I’d love to hear: What you’d want it to do Who would use it (students, engineers, math hobbyists, etc.) What’s missing from existing tools This could be theoretical, geometric, applied math, anything. I’m not a company, just a solo dev trying to make cool tools — if there's a gap, I’d love to build something for it and keep it free to use. Thanks in advance!
