WLED Max controls WLED lights from your iPhone and iPad: LED strips, holiday lights on the roofline and 2D pixel matrices. It needs a WLED controller (an ESP32 or ESP8266 running WLED) and does not work with Bluetooth or IR remote light strips. New in 1.1.4: Pattern Maker. Build bulb patterns like 2 red, 1 white or start from Classic Christmas, Candy Cane or Diwali Diyas, add motion and watch it on your lights as you go. Every feature is free for one light. A one-time purchase adds unlimited lights. No account, no ads, no subscription. EASY SETUP Open the app and your WLED devices appear automatically. Just tap to add them. Got a brand new device still in setup mode? A step-by-step wizard walks you through connecting it to your Wi-Fi. No computer required. You can also add devices by IP address if they're on a different network. FULL CONTROL AT YOUR FINGERTIPS Adjust brightness with a slider or tap 25/50/75/100% quick-set buttons. Pick colors from a full color wheel, choose from quick-access swatches, or dial in a warm-to-cool white temperature. Set up to 6 favorite effects for one-tap access. Everything responds instantly. 180+ EFFECTS WITH LIVE PREVIEWS Every WLED effect renders a live animated preview right in the grid. See exactly what each one looks like before you apply. Search, filter by category (solid, rainbow, fire, 2D, audio-reactive), and tune speed, intensity, custom parameters, and palette in real time. Pair any effect with any color palette. SEGMENTS STUDIO A visual zone editor with drag-to-resize and full 2D matrix support. Split a single LED strip into independent zones and give each one its own effect, colors, brightness, speed, and direction. Light your desk, shelf, and ceiling from one controller with completely different looks. The visual editor shows you exactly what you're building. FULL WLED CONFIG IN-APP Every native WLED setting is available right in the app: Wi-Fi, LED layout, sync interfaces, schedules, macros, user mods, security, and updates. No more opening device IPs in your browser. DEVICE GROUPS Organize lights into groups like Living Room, Bedroom, or Gaming Setup with custom icons. Turn an entire group on or off with one tap. Devices can belong to multiple groups. PRESETS & CLOUD SYNC Save any lighting setup as a preset and reapply it instantly. Build playlists that cycle through your favorites, edit them any time and turn on Shuffle if you like. With iCloud sync, your lights, groups and presets follow you across your iPhone and iPad. OTA FIRMWARE UPDATES Update your WLED firmware right from the app. WLED Max picks the right file for your board and handles the install. Release notes included so you know what's new.
