Control your Sonos speaker system from your iPhone, iPad, and Apple Watch — the remote it always deserved. Nudge is a full speaker controller for iPhone, with a purpose-built Apple Watch app that turns your wrist into a remote. Every speaker, every connected music service, every room — in one fast, focused app. (A quick first-run setup on iPhone finds your speakers and connects your account; after that, both apps just work.) ON YOUR APPLE WATCH Nudge is built specifically for Apple Watch — not a shrunken phone app. Full-bleed album art, precise Digital Crown volume with haptic feedback, Double Tap to play and pause without touching the screen, and a watch face complication that shows what's playing and jumps you straight in. One-handed, glanceable, instant. ON YOUR IPHONE The full controller in your pocket: Now Playing with album art and transport, voice and text search across your library and Favorites, speaker and group management, and DJ Access — all in a clean, focused interface that's faster than the apps you've been using. ON YOUR IPAD Nudge is now on iPad. It isn't a stretched-out iPhone app: it was laid out for the big screen, so you can browse, pick a room and control what's playing without ever leaving the screen you're on. VOICE SEARCH Say what you want to hear — Nudge searches your personal music library and Favorites and plays it. Hands-free voice dictation on Apple Watch while you cook, work out, or move around the house, plus fast search on iPhone. One tap to play. NOW PLAYING Full-screen album art with intuitive playback controls. Precise volume — Digital Crown with haptics on the Watch, smooth sliders on iPhone. Shuffle, repeat, and crossfade. Skip, scrub, and switch rooms in a tap. DJ ACCESS Turn your friends into DJs. One invite and they can control your speakers — play from your library and Favorites, adjust volume, switch rooms. No passwords shared. Safe and secure. Your system, your rules. SPEAKERS AND GROUPS See every speaker and group on your network. Switch rooms instantly. Create and modify groups on the fly. Album art thumbnails show what's playing where, at a glance. FAVORITES Your saved Favorites for one-tap playback — stations, albums, and playlists across all your music services. FAMILY SHARING One subscription covers your entire Apple Family at no extra cost. Requires iPhone with iOS 26.x or later and iPad with iPadOS 26.1 or later. Apple Watch features require Apple Watch Series 6 or later with watchOS 11.6 or later. Compatible wireless speakers on the same Wi-Fi network. Requires a Sonos system on your Wi-Fi network. —- Nudge is independently developed and is not affiliated with, endorsed by, or sponsored by Sonos. Sonos is a registered trademark of Sonos, Inc.
