** Macworld Editors' Choice Award Winner! ** Smithsonian: “Immersive.” CNET: “Spectacular.” Macworld: “Exquisite.” FRAX Frax is an art program that puts the “equations of nature” in the palm of your hand. Frax is powered by fractal geometry, the same principle that creates patterns of self-similarity in our natural world. From spiral galaxies to hurricanes, from tree limbs to branching blood vessels, the universe is filled with endless variation and staggering beauty. Frax visualizes this natural geometric code, so you can explore vast animating digital landscapes and make a masterpiece on your touchscreen. EXPLORE Zoom deep into your creations. Use multi-touch gestures to fly through and explore intricate shapes and patterns. Tilt-to-steer through animating digital worlds, as you challenge yourself to chart a course for a long and beautiful flight –all at a depth range of a trillion-to-one. DESIGN Unleash your inner artist with complex color gradients to smoothly tint and shade your fractal shapes, two light sources for glossy reflections, and novel textures. The combinations are endless: supersmooth or wildly chaotic, metallic sheen or pearly white, subtle shades, stark monochrome or screaming supergloss. Or upgrade to Pro to access almost 100 parameters and controls! SHARE Then share your creations with your friends via Facebook, Twitter and text. Or invite other users to step into your animating world by sharing a live preset link. You can render high-quality images to your photo library or create ultra-high quality 200 Megapixel renders with an IAP. And for the first time, you can now record VIDEO of your Frax animations directly within the app! (Pro IAP required.) Our users have put their designs on canvas, posters, scarves, T-shirts and textiles. The creative possibilities are endless! What will Frax inspire in you? We hope you enjoy Frax!

Fraksl turns your device into a real-time fractal visual engine. Powered by live video feedback, it transforms simple inputs into endlessly evolving, mesmerizing patterns — perfect for live performances, music visuals, generative art, and creative exploration. FILTERS & MIRRORS Apply color filters and mirror transformations to reshape your fractals into new forms. Combine them with layers and modulators for infinite creative possibilities. LAYERS Mix multiple visual sources into your fractals. Use your live camera as input, import images and videos from your library, or receive NDI streams from other apps and devices. Each layer has full control over blend mode, opacity, hue, position, rotation, scale, and chroma keying. SEQUENCES Capture bookmarks of your visual state — filter, mirror, color, and more. Arrange them into sequences with custom transition and hold times for smooth, cinematic playback. Export and share your sequences with others. MODULATORS Automate any parameter with real-time signal sources: Audio — react to sound from your microphone MIDI — connect hardware controllers and DAWs Beat Clock — sync to BPM with adjustable divisions Waveform — generate smooth LFO patterns Motion — use your device's gyroscope and accelerometer Gamepad — connect any controller for hands-on performance Create complex, evolving visuals that respond to music, movement, or external control. CAPTURE & RECORDING Take high-resolution screenshots or record video with optional microphone audio. Share directly from the app. NDI STREAMING Stream your output live over the network to any NDI-compatible software or device. Ideal for live shows, streaming setups, and multi-screen installations.
