Hey Product Hunt User ! I'm the founder of CalcDocu — and I built this because I was frustrated with calculator sites that hide results behind signups, show one number with zero explanation, or haven't updated their tax/legal data in years. CalcDocu has 90+ free tools across 7 categories: 💰 Legal (DUI, Workers Comp, Personal Injury) 🏠 Real Estate & Mortgage (HELOC, Closing Costs) 📊 Personal Finance (Paycheck, Loan, Net Worth) 📄 Business Documents (Invoice, Quote, Purchase Order) ⚕️ Health & Wellness (Calorie, Sleep, Ovulation) Every tool gives: → Instant results — no email, no signup → Itemized breakdown — not just one number → 2026 verified data (IRS, state tax tables, federal rates) → US, UK, Canada & Australia support We also have Android apps on Google Play (Finance Calculator + Invoice Maker) with more coming soon. Would love your honest feedback — what calculator is missing that you actually need?
