## Description

Calculator — Editable History, Tax & Reference.

A simple, powerful calculator with a memo-style editable history. Tap any past calculation to edit the formula or equation, name your result, and reference it in your next math problem. Includes one-tap tax buttons and a notebook-style history for everyday math.

No account registration, no subscription, free to use. Your calculation history is saved only on your device — never uploaded to our servers.

Features
----------------
■ Editable History
Tap any past calculation in the history to edit the formula. Fix a typo, change a number, or update an equation — the result recalculates instantly. No other calculator lets you edit past math like this.

■ Named Results & Cross-Reference

■ One-Tap Tax Buttons
Add or remove tax (consumption tax / sales tax) with a single tap. Customize the tax rate for your region. No more manual percentage math.

■ Full Calculation History
Every calculation is saved automatically in your history. Scroll back anytime to review past results, and tap any entry to edit it. Perfect for keeping track of a long series of calculations.

■ Customizable Themes & Fonts
Choose from multiple color themes and font sizes. Make the calculator easy to read for any age or visual preference.

■ Dark Mode Support
Automatically adapts to your system appearance. Comfortable for the eyes when doing math at night.
