Pocket Calcura

Pocket Calcura is a full-featured scientific calculator built for everyday use and serious number crunching alike. It covers the standard arithmetic operations alongside a complete set of scientific functions — trigonometry (sin, cos, tan and their inverses), logarithms (natural and base-10), powers, roots, and mathematical constants like pi and Euler's number.

Every calculation is automatically saved to a scrollable history log. You can scroll back through previous expressions and results at any time, or tap an entry to reuse it without retyping. The history is stored locally on the device and persists between sessions — no account, no sync, no cloud required.

The interface is built around a clean, extended numpad that keeps all functions accessible without switching between multiple keyboard panels. Font size can be adjusted in settings to suit your preference, and haptic feedback can be toggled on or off. Everything runs fully offline. No registration, no ads, no purchases.

Whether you are working through a quick conversion, checking a formula, or running a longer chain of calculations, Pocket Calcura keeps everything in one place and out of the way.
