Holler — Home Intercom

Talk to every room at once. Holler turns your iPhone into a whole-house intercom. Hold a button — or your iPhone’s Action Button — say your piece, and let go. Your voice plays on the Chromecast and Google Nest speakers you choose, anywhere in the house. No wake words. No “Hey Google.” No yelling up the stairs. Just press, talk, done. MADE FOR FAMILIES “Dinner’s ready.” “Time for school.” “Five minutes!” Reach the whole house — or just the kids’ rooms — in one tap. HOW IT WORKS • Finds the Chromecast / Nest speakers on your Wi-Fi • Group them into rooms and floors • Pick a target — a room, a floor, or Everywhere • Hold to talk; your announcement plays a moment later ACTION BUTTON READY Set your iPhone’s Action Button to Holler and broadcast without even opening the app. PRIVATE BY DESIGN Your voice is sent straight to your speakers over your own Wi-Fi. No account, no servers, no analytics — nothing leaves your network. HOLLER PRO (one-time purchase) Unlock unlimited rooms, floors and groups, saved announcements, scheduling, and multiple Action-Button presets. One purchase covers your whole family (Family Sharing). No subscription. Note: Sonos support on iPhone is coming soon. HomePod and AirPlay speakers aren’t supported, because Apple doesn’t provide a way for apps to broadcast to them.
