Turn your iPhone or iPad into a touch-first projection mapping and video mapping studio. Lazy Lighting lets you warp videos, photos, live camera feeds, animated drawings, and generative VJ visuals onto walls, stages, sculptures, windows, objects, and multi-surface installations—without a laptop. MAP ANY SURFACE Create squares, circles, custom text, cubes, boxes, image silhouettes, and hand-drawn outlines. Drag corners directly on screen to align each projection, bend edges around curved forms, then use masks and cutouts to control exactly where every visual appears. Map several surfaces at once. Assign different content to individual shapes, layer visuals with independent opacity and ordering, and save projects to continue later. CREATE LIVE VISUALS • Explore built-in visualizers, VJ loops, generative shaders, gradients, tunnels, neon effects, and shape-aware animations • Import videos and photos from your device • Use a live camera feed as projection content • Draw and animate original visuals by hand • Crop, fit, mask, layer, and apply real-time effects including kaleidoscope, tile, slide, rotate, zoom, blur, monochrome, invert, and color cycle • Make visuals react to audio or control parameters with MIDI • Animate controls with BPM-synced LFO and envelope modulation • Use hand and face tracking for expressive control BUILD A COMPLETE SHOW Create scenes and switch between them live, or arrange them on a timeline. Add an audio track, trim and duplicate clips, automate visual parameters, and move between looks with fade or dissolve transitions. Export the finished projection-mapped show in 720p, 1080p, or 4K with audio. Save it to Photos or send it to a compatible receiver running Lazy Lighting Link. EXPORT ONCE. PLAY WITHOUT YOUR PHONE. Once the transfer is complete, Lazy Lighting Link saves and loops the show on the receiver. Close the app and free your iPhone or iPad—the projection keeps playing without your device remaining connected. CONNECT YOUR WAY Connect by HDMI with a compatible USB-C or Lightning adapter, use AirPlay, or connect through Lazy Lighting Link. External display output keeps the controls on your device while the visual output fills the projector. Lazy Lighting is made for projection artists, VJs, DJs, musicians, performers, stage and event designers, galleries, installations, window displays, parties, home ambience, and Halloween, Christmas, or holiday projections. Create the map. Build the visuals. Perform live—or export once and let Lazy Lighting Link keep it playing. A compatible projector or display and a wired or wireless connection are required for external output. Lazy Lighting Link export requires a compatible receiver on the same network. Some features require a subscription. Terms of Use: https://lazylighting.com/ios-terms Privacy Policy: https://lazylighting.com/ios-privacy
