Hi Product Hunt! 👋 I’m the maker behind CalculatorCloset.com. What inspired this? The inspiration came from a place of pure frustration. I found myself constantly needing quick, precise calculations—mortgage rates, ROI, or even simple unit conversions—but every time I turned to existing sites like calculator.net, I was met with a wall of ads, pop-ups, and slow load times. I just wanted an answer, not a digital obstacle course. The problem I wanted to solve: I wanted to build a "zero-friction" environment. Most utility sites today feel like they belong in 2005; they track your every move and force you to navigate through clutter. I wanted to prove that you can provide high-precision tools while respecting a user's time and privacy. How the process evolved: Originally, I thought about making it an ad-free subscription service. But as I worked on the launch, my approach shifted. I realized that for a utility tool, even a login screen is "friction." I decided to ditch the registration entirely and settle on a minimalist ad model—strictly with minimal non-intrusive placements—to keep the lights on without killing the user experience. It’s been a journey of "stripping away" rather than "adding on." I’d love to hear your feedback on the speed and which specific calculators you’d like to see added next!
