Ferromagnetic: Music Visualizer & VJ App for iPhone, iPad, and Mac Ferromagnetic turns Spotify, SoundCloud, YouTube, and any other sound into stunning real-time visuals. It's a professional audio visualizer for everyone, from home listening and house parties to DJ sets, live shows, and VJ performances. FM Visualizer: Effortless Background Visuals Start a System Broadcast and Ferromagnetic follows the audio of Spotify, SoundCloud, YouTube, and most other apps on your device. Or use the microphone to visualize anything around you, from a DJ set to a live band. The 12-band frequency analysis and tunable beat detection catch every beat and note, and a GPU-accelerated Metal engine renders it all in multiple layers. Pick a Vibe like Calm, Energetic, Trippy, or Retro to set the mood in one tap. Or let Ferromagnetic take the wheel and build new scenes on its own from over 1,000 combinations. Set how fast the scenes change and choose from ten transition styles, including Morph, Zoom, and Color Distance. Choose from over 20 audio-reactive effects: the signature Ferrofluid and Electromagnetic fields, plus Starfield, Petals, Laser, Glitter, Cloud, Refractions, and more. Build your own scene from three effect layers and particles, each with its own blend mode, and tune every layer to the bass or the highs. Particles burst and flow with the sound, and glitch and shake hit harder as the volume rises. Transform the image with Kaleidoscope, Droste Spiral, Voronoi Mirror, or Tunnel, then shape the look with pixelation, dithering, blur, and color palettes like Vivid, Warm, or Triadic. Show your own logo text on screen, perfect for cafes, bars, and venues. Mirror the visuals to a TV or projector with AirPlay or a cable, and the screen stays awake for as long as the music plays. Visuals render at up to 60 fps. FM Producer: Live Visual Performance On iPad, FM Producer turns Ferromagnetic into a VJ app for live shows. The dual-deck interface works like a DJ controller: prepare the next scene on one deck, then crossfade it in. Add the iPad camera or NDI® sources as live layers, and send your visuals to OBS, Resolume, and other apps with NDI output. Connect a MIDI controller or keyboard, map any control with MIDI Learn, and trigger effects and scenes without touching the screen. FM Producer also unlocks the complete Mac app, with video, image, and 3D model layers, presets, and video recording. Try It Free Download Ferromagnetic for free, then unlock only what you need with an affordable subscription or a one-time purchase. One purchase works on iPhone, iPad, and Mac.

About

Beatworld

Features

Pick a song, and the world on your screen starts moving to it. Beatworld is not just a waveform. The kick makes a crowd of balls jump, the snare sends out a shockwave, and when the chorus hits, the whole world lights up. Save what you see as a vertical video in one tap. WORLDS THAT DANCE TO YOUR MUSIC - Bouncing Balls: balls bounce on every kick, the floor shakes with the bass, and shockwaves ring out on the snare - Dancing Cats: neon cats change their choreography every two bars: steps, claps, waves, solos, and a big jump together on the drop - Neon Band: a robot band plays along: kick drum on the kick, sticks on the snare, and the crowd goes wild on the drop - Night Drive: cruise a neon city at night where the windows are an equalizer, through tunnels and over bridges, speeding up on the drop - Photo Beat: your own photo turns into pulsing tiles, shatters on the drop, and snaps back together on the next bar - Neon Tunnel: fly through a neon tunnel whose lights race along with the beat CLASSIC VISUALIZERS - Spectrum: every band from deep bass to bright highs becomes a bar of light - Circular Spectrum: a ring of frequencies that pulses with each beat - Particles: thousands of particles rise and burst with the song, swirling into vortexes and flowers - Kaleidoscope: a neon kaleidoscope that blooms on the beat and bursts outward on the drop - Laser Show: festival lasers sweep the venue, changing patterns with each part of the song SYNC THAT FEELS RIGHT When you load a song, Beatworld analyzes it once, on your device: loudness, bass, mids and highs, kick, snare, hi-hat, tempo, where each beat falls, and how the energy builds across the whole track. The visuals lean in just before the chorus and explode the moment it lands. Bluetooth headphone delay is compensated, too. SAVE AS A VERTICAL VIDEO - Export 9:16 vertical videos (1080x1920) to your photo library or share them right away. Square (1:1) and wide (16:9) are available too - Choose the part of the song to export - The song's audio is included MAKE IT YOURS Adjust color, sensitivity, glow, camera effects, thickness, particle amount and more for each visual. WHICH SONGS YOU CAN USE DRM-free audio files in the Files app (MP3, M4A, WAV, AAC, AIFF and more) and the demo track in the app. Copy-protected streaming songs, such as Apple Music tracks, cannot be used. Before you publish a video, make sure you have the rights to the music. Songs are analyzed on your device only and are never uploaded. WHAT IS INCLUDED, AND WHAT NEEDS A PURCHASE The core visuals can be used without paying. Without Premium, exported videos carry a small watermark in the corner and are 30fps, and the app shows ads. Some visuals, watermark-free export and 60fps export require Premium (an in-app purchase). Watching a video ad unlocks one watermark-free export, or a locked visual until you close the app. SUBSCRIPTION "Beatworld Premium" is offered as an auto-renewing subscription (monthly or yearly): no ads, no watermark, every visual, and 60fps export. The yearly plan may include a free trial for eligible users. Payment is charged to your Apple ID account at confirmation of purchase. The subscription renews automatically at the same price unless it is cancelled at least 24 hours before the end of the current period. LIFETIME "Beatworld Premium (Lifetime)" is a one-time purchase that unlocks the same Premium forever. It does not renew. NOTES You can manage or cancel the subscription in your Apple ID settings under Subscriptions. If you cancel, Premium stays active until the end of the current period. Partial periods are not refunded. RESTORE PURCHASES If you have purchased before, tap "Restore Purchases" on the purchase screen.
