Hi Product Hunt! I’m the maker of PerfectCalc. For me, a great calculator is about more than getting the right answer. I wanted a keypad that makes sense, results that update as I type, a way to edit expressions without starting over, and a calculation history I can actually use—including summing past entries. I also wanted the tools I need less often to be there when I do need them: scientific functions, currencies, fractions, unit conversions, mortgages, and finance tools. PerfectCalc is my attempt to bring all of that together in one app for iOS and Android. I’d love to hear what works well for you and what could be better. What’s one calculation task you wish your current calculator made easier? I’ll be here to answer questions and learn from your feedback. Thanks for taking a look!
