iPhone
New: take the music from your own videos — from Photos, Files or a link — keep it as an audio file, and make Refract light or dark.
TURN ANY TRACK INTO A VIDEO THAT MOVES WITH IT
Refract is an audio-reactive video studio for your iPhone. Load a song and a real-time engine listens to its beat, bass and energy, then choreographs every layer to the music. No keyframes. No guesswork. No template that ignores your track.
No account, no sign-in. Your music and your videos never leave your phone.
YOUR MUSIC, FROM ANYWHERE
Pick a song from Files, iCloud Drive or Voice Memos. Take the soundtrack straight from a video you shot, in Photos or Files, or from a direct link to an audio or video file. Refract checks the video first, keeps only its sound, and lets you hear it before you begin. Keep that sound as its own audio file in one tap.
A VISUAL ENGINE THAT LISTENS
• 8 GPU-accelerated visualizers — Linear Spectrum, Waveform, Ring, Polar Bars, Dual Wave, Pulse, Streaks and Dots
• 20 studio effects — Glow, VHS, CRT Scanlines, Film Grain, RGB Shift, Oil Paint, Fisheye, Wave Warp, Swirl, Posterize, Edge Detect and more
• 8 particle overlays for depth, atmosphere and motion
• 6 auto-choreographed looks — Neon Pulse, VHS, Poster, Liquid, Handheld, Drift — each a finished edit in a single tap
• A text tool with 8 typefaces and 4 ink styles, and type that pulses with the bass
A REAL TIMELINE, NOT A TEMPLATE
Every layer lives on a full multi-track timeline. Move it, retime it, restyle it, bind any parameter to the audio, and watch the preview follow at 60 fps. Trim a five-minute track to its strongest thirty seconds, add precise fades, and export exactly that.
READY FOR EVERY PLATFORM
One-tap presets for portrait, square, tall and widescreen — 9:16, 1:1, 4:5 and 16:9 — with resolution, frame rate and quality set for you. Or take full manual control, up to 4K at 60 fps, at any length.
LIGHT OR DARK
Refract follows your iPhone's appearance, or stays in the one you choose.
PRIVATE BY DESIGN
Analysis and rendering happen on your phone's GPU. Nothing is uploaded, so creating and exporting work anywhere — on a plane, in a studio, offline. Refract counts which features get used, anonymously and with no identifier of any kind, so we can see what to improve.
START FREE, GO PRO WHEN YOU'RE READY
Unlimited projects and exports, every aspect ratio, your own photos and the full timeline editor — free. Refract Pro unlocks the entire catalogue, 4K at 60 fps, unlimited length and watermark-free export. Everything you make keeps working and keeps exporting, whichever you're on.
Made for musicians, producers, DJs, podcasters and labels who need a release-ready visual for every track.
