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. POWERFUL FEATURES - Reset button to return to the full fractal view - Real-time zoom level display from 1x to trillions and beyond - Iteration count indicator shows computational complexity - Center coordinates display your exact location in the complex plane - Rendering mode indicator for GPU Float, GPU Extended, or CPU Arbitrary - Precision warnings when approaching hardware limits - Share your favorite discoveries with friends OPTIMIZED PERFORMANCE FrackTell is built with Metal for maximum GPU performance and multi-threaded CPU processing for extreme zooms. The app intelligently chooses the best rendering method for your zoom level, ensuring smooth performance whether you are at 10x or 10 quadrillion times magnification. PERFECT FOR - Mathematics enthusiasts and students - Fractal art lovers - Anyone curious about infinite complexity - Meditation and relaxation with chaos music - Teachers demonstrating mathematical concepts - Digital artists seeking inspiration

Build a robot. Teach it to find its way. Watch it come alive! Wobblebots is a wordless robot workshop for kids aged 3-7, with first steps in coding built in. There is no reading at all: your child plays everything without a single word on screen. Pick a head, a body, arms and legs - every robot bounces, hops, rolls or twirls in its own silly way. LITTLE CODER MISSIONS • Lay arrow tiles, press play, and your own robot walks the program • Maze after maze on winding roads: fix a program that goes wrong, fold long walks into counted steps • Keep going through the missions and win the maze maker: build your own with bushes, rocks, ponds, a lamp and a battery to charge on the way - then solve it • The first four missions are free - finish them and a brand-new maze waits every day, free for everyone THINKING GAMES • Which piece is missing? Parts fly onto the robot when you find them • Which robot is the odd one out? • Turn the wooden blocks so the current runs from the battery to the robot • What comes next? Pick the gumball that keeps the pattern going • Flip the cards and find the matching pairs • Put the picture back together, piece by piece • The first levels of every game are free A GENTLE DAILY WORKSHOP • Friendly customers order robots - build them and fill your sticker album • Earn hats by finishing the day's orders • When the day's orders are done, a cheeky rival drops by for a dance duel - and always leaves as a friend • A new robot arrives every month HOME AND BEYOND • Give your robot a bath with bubbles and ducks, cook a soup in the kitchen • Build a rocket and hop planet to planet across the solar system - every planet free • Paint every part, pick a scene, compose a dance • Stand your robot in your own room with the camera FOR GROWN-UPS • A daily play time you set behind the grown-up button: in the last minute night falls, then the robot goes to bed until tomorrow • No ads, no subscription, no data collected, works offline • Progress syncs with your own iCloud • One optional purchase unlocks everything, for the whole family Privacy: https://vilusion.com/wobblebots/privacy Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
