Hi Product Hunt! 👋 I built Calcora because I wanted a scientific calculator that was useful for both quick everyday math and more advanced calculations without feeling crowded or complicated. It includes standard and scientific calculator modes, trigonometric functions, logarithms, powers, roots, constants, parentheses, percentages, and a local calculation history. I also designed it to work comfortably on phones and tablets, with both light and dark themes. Calcora is completely offline. It does not require an account, show ads, use analytics, track activity, or request internet access. I built the app natively for Android using Kotlin and Jetpack Compose, and I’m continuing to improve it based on real feedback. I’d especially appreciate feedback about the scientific keypad, calculation display, and overall ease of use. What function do you use most often in a scientific calculator?
