Snap Tool Suite - 300+ free calculators & tools — no signup, no paywall

Hey Product Hunt 👋 I kept hitting the same wall: I just want to calculate one thing — how much acid my pool needs, what my mortgage really costs, a quick invoice — and every result is buried under a signup wall, an email gate, or a "download the app." So I built the opposite. Snap Tool Suite is 300+ free calculators, estimators, generators, and checklists. No account. No paywall. No "enter your email to see the result." You open the tool, you get the answer, you leave. That's the whole deal. A few people seem to like most: • Pool care set — pH, chlorine, alkalinity, volume, dosing (this is the corner I know best) • Job offer letter template + the money tools (mortgage, compound interest, invoices) • Everyday stuff — BMI, tip, date math, unit converters It's early and I'm adding tools weekly. I'd genuinely love to hear: what calculator do you wish existed but can never find a clean version of? I'll build the best suggestions. Thanks for taking a look 🙏
