ProCalc is a Flutter-based calculator application designed to provide an intuitive and powerful arithmetic experience. It mimics the iOS-style calculator while introducing additional features such as history tracking, memory functions, and advanced arithmetic.
✅ ProCalc is fully functional and can be used as a basic and advanced calculator. Future updates may include scientific calculator features, graph plotting, and dark/light theme toggles.
✔️ Addition, Subtraction, Multiplication, and Division
✔️ Percentage Calculation
✔️ Supports decimals and multi-digit numbers
✔️ Exponentiation (Power calculations like 2^3)
✔️ Trigonometric Functions (sin, cos, tan)
✔️ Parentheses Support (e.g., (2+3) * 4)
✔️ View past calculations in a scrollable history panel
✔️ Tap on a previous result to reuse it
✔️ M+ (Memory Add) - Store values in memory
✔️ M- (Memory Subtract) - Deduct values from memory
✔️ MR (Memory Recall) - Retrieve stored values
✔️ MC (Memory Clear) - Reset memory storage
✔️ A sleek and modern iOS-like calculator interface
✔️ Color-coded buttons:
- Orange for operations (+, -, ×, ÷)
- Light gray for functions (C, ±, %)
- Dark gray for numbers (0-9)
✔️ Works on all screen sizes
✔️ Optimized for both phones and tablets
