CalcuGo is designed for both phones and tablets, with responsive layouts and light and dark appearance options.

Hi Product Hunt! 👋 I built CalcuGo because I was tired of opening different apps just to do a quick calculation, convert a unit, or check the difference between two dates. So I decided to put the tools I use most into one simple Android app. CalcuGo includes a calculator for everyday and longer equations, unit conversion across 12 categories, date and age tools, calculation history, and layouts made for both phones and tablets. It also supports light and dark mode. I wanted to keep it simple and private, so the app works fully offline. There are no accounts, ads, analytics, activity tracking, or internet permission. I’d really appreciate honest feedback, especially about the calculator experience, unit categories, and tablet layout. Is there another useful calculation tool you think I should add?

The fact that you intentionally left out internet permission and account requirements speaks volumes about respecting user privacy. That kind of restraint in a calculator app is refreshingly rare these days.
