Hey Product Hunt! 👋 I built Gaugeify because I was tired of calculator sites that make you sign up, sit through a pop-up, or hit a paywall to see a result that took 0.3 seconds to compute. What Gaugeify is: — 50+ free calculators across 7 categories (finance, health, business, education, housing, math, social) — Every tool runs in your browser — nothing sent to any server — Zero accounts. Zero paywalls. Zero upsells. Ever. Some tools I'm particularly proud of: 🏦 Mortgage Calculator — full PITI breakdown including PMI and amortization schedule 📈 Compound Interest — year-by-year chart with the Rule of 72 😴 Sleep Cycle Calculator — shows optimal bedtimes based on 90-min cycles 🍅 Pomodoro Timer — with session tracking and custom intervals 💳 Debt Payoff — snowball vs avalanche comparison side by side 🎨 Color Picker — HEX/RGB/HSL/RGBA converter with palette generator and WCAG contrast checker What's coming next: E-commerce & Seller tools (Amazon FBA, Etsy fees, PayPal fees), Content Creator tools, and Faith & Giving calculators (Zakat, Tithe). Happy to answer any questions — and if you find a calculation that's off or a tool you wish existed, tell me here. I build what users ask for. — Ade Launch Tags (Select up to 5 on Product Hunt — these determine which topic feeds your product appears in) TagWhyProductivityHighest traffic topic on PH.

Launch Day Checklist Before you submit: Screenshot or record a 15–30 second GIF of the compound interest calculator in action — visual products get far more upvotes than text listings Set your thumbnail: dark background (#0D0D14), the Gaugeify logo centered, "50+ Free Tools" underneath in teal — clean and stands out in the feed Schedule your launch for 12:01 AM Pacific Time — this gives you the full 24-hour voting window from the start of the day When it goes live: Post your maker's comment immediately (it gets pinned) Share the link in relevant subreddits the same morning: r/InternetIsBeautiful, r/personalfinance, r/financialindependence, r/GetMotivated (for the sleep/health tools) Post on your personal social — every upvote in the first 2 hours matters disproportionately for the algorithm The one thing that wins on PH: reply to every single comment on launch day, no matter how small. Products with active founders in the thread convert browsers to upvoters consistently.
