Calculator+ Scientific & Basic

A calculator that keeps up with you — standard operations, full scientific mode, persistent history, and a clean design that gets out of your way.

🔢 **TWO MODES, ONE APP**

**Standard mode** covers everything you need day to day: addition, subtraction, multiplication, division, percentages, sign change, and parentheses with correct order of operations.

**Scientific mode** adds the tools for advanced math: sin, cos, tan (and their inverses), log, natural log (ln), square root, square, powers (x^y), the constants π and e, factorial, and switchable radians/degrees mode.

📋 **HISTORY THAT WORKS FOR YOU**

Every calculation you run is saved in a persistent history log. Scroll back through previous results, tap any entry to reuse it, and build on earlier answers without retyping. History survives app restarts — it's always there when you need it.

💾 **MEMORY FUNCTIONS**

Store values with M+, subtract with M−, and recall them with MR. Memory makes it easy to carry a running total or reference a fixed number across multiple calculations.

🎨 **THEMES & READABILITY**

Choose between light, dark, and color themes to match your preference or reduce eye strain. Adjustable font size keeps numbers readable on any screen. Subtle haptic feedback (optional) confirms every key press.

⚡ **FAST, OFFLINE & PRIVATE**

No internet connection required. All operations run instantly on your device. No accounts, no cloud sync, no data collected. Just a fast, reliable calculator that works anywhere.

Whether you're splitting a bill, checking a percentage, solving a trigonometry problem, or working through a multi-step equation — Calculator+ handles it cleanly and keeps your work organized.
