Explore amazing fractals
Free · Designed for iPad. Not verified for macOS.
Dive into infinite beauty. Explore the Mandelbrot set with unlimited zoom, hear fractals as music, discover Julia sets, and unlock wisdom from the Chaos Oracle.
Discover the infinite beauty of mathematics with FrackTell, the most advanced Mandelbrot set explorer for iOS. Journey into the depths of fractal geometry with unlimited zoom, stunning visualizations, and unique features that transform mathematics into art and music.
INFINITE EXPLORATION
Zoom forever into the Mandelbrot set with no practical limits. FrackTell intelligently switches between GPU-accelerated rendering for instant results and multi-core CPU processing with arbitrary precision for extreme zooms beyond 100 trillion times magnification. Every zoom level reveals completely new structures and patterns that never repeat.
INTELLIGENT RENDERING
- GPU Float Precision: Lightning-fast rendering up to 100x zoom
- GPU Extended Precision: Crystal-clear quality up to 100 trillion times zoom
- CPU Arbitrary Precision: Unlimited zoom with perfect mathematical accuracy
- Adaptive iteration counts that scale with your zoom level for optimal detail
- Real-time performance indicators show you which rendering mode is active
CHAOS MUSIC
Experience fractals through sound! Enable Chaos Music to hear the mathematical beauty around you. FrackTell continuously samples 16 points in a spiral pattern and converts iteration counts into musical notes using a pentatonic scale. Every location in the fractal produces a unique sonic signature that loops and updates as you explore.
CHAOS ORACLE
Let the fractal speak to you! Tap Speak Chaos to hear grammatically perfect sentences generated from your exact position, zoom level, and iteration count. The AI-powered Chaos Oracle uses your location as a seed to create unique philosophical insights and mystical observations. Every location generates different wisdom.
JULIA SET DISCOVERY
Every point in the Mandelbrot set has its own unique Julia set fractal! Long press anywhere to instantly view the corresponding Julia set. Points inside create connected island patterns, boundary points produce intricate fragmented fractals, and points outside create disconnected dust patterns.
INTUITIVE CONTROLS
- Pinch to zoom smoothly in and out
- Drag to pan across the fractal landscape
- Double-tap to zoom in 3x on any point with smooth animation
- Long press to view Julia sets
- Tap the palette button to cycle through 12 beautiful color schemes
BEAUTIFUL VISUALIZATIONS
- Smooth color gradients with adjustable hue shifts
- 12 preset color palettes from cool blues to warm oranges
- Real-time rendering with no lag during exploration
- High-resolution export to save and share your discoveries
- Dark mode optimized interface that lets the fractal shine
EDUCATIONAL AND INFORMATIVE
Learn about the mathematics behind the beauty with detailed information about what the Mandelbrot set is and why it is infinitely complex, how the simple equation creates infinite detail, the relationship between Mandelbrot and Julia sets, the history of fractal geometry, and how different rendering techniques work.
