benoît M vs SpiroCanvas Spirograph Mandala

benoît M is a visual exploration of the Mandelbrot set — one of the most iconic and fascinating shapes in mathematics. Named in homage to Benoît Mandelbrot, who discovered this fractal-set named after him in 1979. The mathematician introduced the world to fractal geometry. This app lets you dive into a universe created from one deceptively simple formula: repeat z² + c, again and again. From that small rule emerge endless spirals, islands, valleys, coastlines, and self-similar structures that continue to reveal new detail as you zoom deeper. With real-time Metal rendering, benoît M turns fractal exploration into a smooth, visual experience. Pinch to zoom, pan to move, and double-tap to dive into interesting regions. Switch between classic Mandelbrot rendering and a beautiful pseudo-3D relief mode that gives the fractal a sculptural, almost metallic depth. Customize the look with image gradients, procedural palettes, inverted or flipped color styles, and adjustable iteration quality. When you find a scene worth keeping, export it as a square high-resolution PNG — up to 8K — directly to your Photo Library. Features: - Explore the Mandelbrot set interactively - Smooth Metal-based rendering - Classic Mandelbrot and pseudo-3D relief modes - Image-based and procedural color gradients - Adjustable iteration depth - Pinch, pan, and double-tap navigation - High-resolution PNG export: 2K and 8K - Saved app state, so you continue where you left off A compact tribute to Benoît Mandelbrot and the beauty of fractal geometry Whether you are fascinated by mathematics, generative art, abstract visuals, or simply beautiful patterns, benoît M invites you to explore infinity — one zoom at a time.

SpiroCanvas is a spirograph app and mandala maker. Pick a disc, choose a pen hole, tap Draw, and watch the pen trace a hypotrochoid curve across the canvas: the classic Spirograph toy, on your phone. Layer curve on curve to build mandala-like compositions, then save or share them. FEATURES Draw & Design - 10 disc sizes, from simple triangles to complex rosettes - Custom disc ratios for unlimited pattern variety - 10 pen hole positions for different curve shapes - 8 colors plus a custom color picker and rainbow mode Three Track Modes - Circle: the classic circle-in-circle spirograph patterns - Oval: elliptical tracks for asymmetric, organic shapes, with 20+ presets - Shapes: roll the disc around a heart, star, flower, triangle, square, egg, stadium or blob - Shapes also covers every digit 0-9 and every letter A-Z, for names and numbers as patterns - Run the disc inside or outside the track for two different families of curve - Independent inner disc shapes Layers - Stack unlimited patterns on one canvas - Show or hide individual layers - Undo and clear with one tap - Per-layer transforms: scale, rotate, and drag to reposition Save & Share - Export high-resolution PNG images - Share to social apps, messaging, or your photo library - Save compositions to revisit and keep editing later - Auto-save restores your session Pattern Gallery - Browse a curated gallery of pattern presets - One tap to load and draw any preset Extras - Adjustable drawing speed, 0.25x to 4x - Sound effects while you draw - Available in 11 languages - Works on iPhone and iPad No ads, no in-app purchases, and no account required.
