Doodler is a vibrant, interactive drawing app that transforms simple sketches into dynamic visual experiences. Designed for creative expression, it combines traditional drawing tools with magical particle effects, allowing users to create everything from classic sketches to animated digital art. The app features a sleek dark-themed interface and real-time particle physics for immersive doodling.
Key Features:

15+ Brush Effects
Fairy Dust, Stars, Snowflakes, Hearts, Fire, Rain, and more—each with unique animations.

Customizable Tools

20-color palette with quick selection

Adjustable brush size (1-25px)

Line stroke toggle (enable/disable outlines)

Particle Physics Engine

Real-time animations with properties like gravity, fade effects, and motion:

Fire floats upward with shrinking particles

Rain falls with gravity acceleration

Fairy dust drifts gently

Snowflakes rotate as they descend

Canvas & Controls

800x600 drawing canvas with shadow effects

One-tap clear/save functionality

Intuitive gesture-based drawing (drag to create)

Optimized Performance
Particle system updates at 60 FPS with automatic cleanup of off-screen/animated elements.

Technical Highlights:

SwiftUI with Canvas for hybrid path/particle rendering

MVVM Architecture (DrawingViewModel state management)

Physics-based particle behaviors (velocity, rotation, fade)

Custom shape rendering (hearts, stars, spirals, snowflakes)

Dynamic color/size adjustments with @Published properties

Ideal For:

Digital artists seeking playful tools

Educators teaching physics through visuals

Anyone wanting to create shareable animated art

Example Creation:
Draw a spiral with the Fire effect to generate rising embers, or use Rain with blue color for a storm scene—each stroke becomes alive with motion.
