About this app

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.

PRESETS
Save and recall your complete setup — layers, modulators, mappings, sequences, and all settings — in a single tap.

AVAILABLE IN 9 LANGUAGES
English, Dutch, Spanish, French, German, Italian, Russian, Portuguese, and Polish.

FREE TO USE
Fraksl is free with core features included. Unlock additional filters, mirrors, layers, modulators, capture, streaming, and save slots individually or as a full bundle.

Ratings and reviews

Visually stunning. You'll want to download this app at least once just to see the dizzying effects it can create. It's really very beautiful. Of course, the controls are a bit awkward and it's hard to do anything on purpose. You can rotate (diffracting the image) and zoom in/out. It's very kaleidoscopic (except when you accidentally fold all the colors in on themselves and are left w/ one, but there's a reset button.) I only wish you had options to construct your own or view different fractals.

Damn that's good math. You may need a decent device though it's possible to downscale the resolution and still get pretty incredible images. At 4K actually at extreme or above it's truly mind-blowing !!! Would be nice if it included a couple more starting algorithms but not a deal breaker. Free version includes a bunch of customizable settings and the extremely inexpensive pay version $1.99 03/2022 could easily demand double or triple. Ads, there are not any. Thank you Thank you thank you!

My first ever review. But this app is something else!! Amazing, brilliant, trippy, delightful. Each time I open it for few mins I find myself immersed in its endless beauty. That is the app that I thought to myself "wow this is so good that I want to pay to developer to support him/her/them" AWESOME!!! Thank you 🙏 Edit: when I record video, the sound quality is super low, as if the sample rate is from old walkie talkie with noises and distortions, any idea why??
