Whole-home audio control
Great hardware. Forgettable app. Electrofonic replaces the one that shipped with your multizone amplifier — it finds the amplifier on its own, then puts every room on one screen, under the names you use and tuned the way you like.
Coming to the App Store
Requires iPhone, iOS 18 or later.
Every zone sits on one screen with its volume, its source, and its power. One look tells you what's on and how loud. Whole house on for a party, off on your way to bed — without leaving that screen. A zone that's off doesn't vanish from the list; it stays where it stands and says so. A zone you never wired can leave it altogether. Drag a fader and the zone follows your thumb, one step at a time.
Name your zones and your sources, then set bass, treble, and balance for each one — seven steps either side of flat. Give a zone a maximum volume and nothing gets past it: not a guest with the app, not the keypad on the wall. The kitchen can sit brighter than the living room and quieter than both, and it stays that way. The settings live on the amplifier, not on your phone.
Group the zones you always play at once and one fader moves them all, holding the levels you already set between them. A long press and a name makes the group; zones join or leave it the same way. It gets one mute and one power control for everything inside it — and any zone in it is still one tap away on its own.
Party mode puts every zone on one source at one level and keeps it there: turn it up in the kitchen and the patio follows. You pick what plays and how loud before anything moves, so nobody gets blasted at full volume. Zones that should sit it out can be left out. End the party and nothing jumps: every zone keeps the source and level it's on.
Ask Siri instead — mute a zone, turn one up, play a source, start a party. It works with the app closed, and Siri names the zones it actually reached rather than just saying OK. Want it in one tap? Build your own shortcut and put it on the Home Screen, in a widget, or on the Action button.
The app that came with your amplifier hasn't materially improved since the day it shipped. Electrofonic is native to iOS and it behaves like it. Text arrives at the size you already told your iPhone you want, and the layout follows instead of breaking. Sliders tick under your thumb, one step at a time, and stop at the ceiling you set for that zone. Dark by default, light if you'd rather — one tap in Settings.
The same care goes into the parts you may never need. VoiceOver support is first-class — every control is reachable and speaks its real value, from the first screen of setup onwards. Turn on Increase Contrast and the sliders, their tracks, and the grayed-out states all deepen. Ask your iPhone to reduce motion and the app stops moving.
Electrofonic supports many popular multizone amplifiers — great hardware that never got a great app. If yours is on this list, you're ready to go. Not on it, but it looks like one that is? These units are rebadged from a common design, so send us the model and we'll tell you.
Every one of them takes 6 sources. They also daisy-chain: up to 3 units act as one system, and they don't have to match. Electrofonic addresses every zone across the chain, so a house bigger than one unit is still one screen.
And you won't have to go hunting for an IP address. On an ordinary home network Electrofonic finds the amplifier itself, connects, and remembers it. If yours isn't ordinary, or nothing answers, Support covers the rest.
Put the whole house in one app. Requires a supported multizone amplifier on your network and an iPhone running iOS 18 or later.
