Hi Product Hunt 👋 Thanks for checking out All in One Calculator! The idea started from a pretty simple frustration: every time I needed a specific calculator for something (grades, GPA, SAT scores, finance, health, etc.), I had to jump between different websites, many of which were cluttered with ads, confusing, or locked behind paywalls. I wanted one clean place where people could find reliable calculators without distractions. So I set out to build a single platform that brings together useful everyday calculators in one fast, simple interface. The main goal was accessibility: no logins, no hidden fees, no complicated steps. Just enter your numbers and get your answer. During development, the biggest change in approach was focusing more on real user behavior. I started watching which calculators people used most, what confused them, and what they searched for. That feedback pushed me to simplify the UI even more and keep adding new calculators based on real demand instead of just my original roadmap. This launch is only the beginning. I would love your feedback on what calculators you use most and what you wish existed that doesn’t yet. Thanks for the support, and I’m excited to hear what you think! 🚀
