Simple Calculator

The standout feature of this app is the "Easy-to-Read Display," which shows your formula across two lines while you calculate. For example, when calculating "100 + 50", the screen displays: 100 + 50 This makes it visually intuitive to see exactly what you are calculating at any moment. Furthermore, the answer is displayed in real-time as you type, allowing you to see both your current formula and its result all at a glance. This clarity helps prevent typos and calculation errors, fully supporting your daily math needs. 【✨ Key Features】 📖 Powerful History Function Tap past formulas to restore them into your current calculation. Add notes to each history item (e.g., "Lunch," "Travel Expenses"). Share calculation results with other apps. Use checkboxes in your history to see the subtotal of multiple calculation results. ⚡ Custom Shortcut Keys Register frequently used calculations like "+8%" or "-20%" as shortcut keys. Calculate sales tax (tax included/excluded) and discounts with just a single tap. Freely add, delete, and rearrange keys to fit your preferences. 🔁 Convenient Constant Calculation (Repeat Calculation) Simply press the "=" key after a calculation to repeat the last operation. (Example) After calculating "100 + 30 =" to get 130, pressing "=" again repeats "+ 30" to make it 160. Pressing "=" once more changes it to 190. 【⚙️ Additional Features】 📳 Haptic Feedback (Vibration): Provides vibration feedback when tapping buttons to ensure accurate input. 🌙 Dark Mode Support: Automatically switches to an eye-friendly dark mode based on your device settings. 🎨 Custom Theme Colors: Choose your favorite accent color to customize the calculator just for you.
