Alavu 📏

Alavu (the Malayalam word for Measure) is a premium, high-precision Material Volume Calculator designed for contractors, engineers, and DIY enthusiasts. Built with React Native and Expo, it provides a sleek, dark-themed experience for calculating the volume of cuboids and cylinders with real-time updates and unified results.

✨ Key Features

• Dual Shape Support: Calculate volumes for both Cuboids (Length × Width × Height) and Cylinders (π × Radius² × Height).
• Multi-Unit Integration: Convert and calculate seamlessly between:
  • 🌍 Meters (m)
  • 📏 Centimeters (cm)
  • 📐 Inches (in)
  • 🦶 Feet (ft)
• Unified Result Dashboard: A split-pane real-time display showing your inputs alongside the final result in cubic meters (m³).
• Responsive Animations: Smooth transitions and auto-scrolling focus for a frictionless data entry experience.
• Premium Aesthetics: A custom "Amber Glow" dark theme designed for high visibility in various lighting conditions.

📐 Calculation Logic

1. Cuboid Volume

Uses the formula: $$V = L \times W \times H$$ Inputs are normalized to meters before calculation.

2. Cylinder Volume

Uses the formula: $$V = \pi \times r^2 \times h$$ Inputs are normalized to meters before calculation.
