Holler
A push-to-talk intercom for your home speakers. Hold one button, speak, and your voice plays on a speaker in another room.
"Hey kids, dinner is ready."
That is the whole product.
How it works
- Open Holler. It finds the speakers on your Wi-Fi in the background and preselects the one you used last.
- Press and hold the Talk button and say what you need to say.
- Let go. Your voice plays on that speaker. Where the speaker supports it, your voice is live while you hold the button; otherwise it plays the moment you release.
The speaker name sits under the button. Tap it to pick a different speaker. There is no sign-in, no onboarding tour, no history, and no feed. Setup is choosing a speaker once.
Hands-free
The iPhone Action button, Siri ("Hey Siri, Holler") and Shortcuts can start a holler to your usual speaker without touching the screen. Tap the button once to stop. That is the only tap in the app.
Works with
| Speaker | How |
|---|---|
| Sonos | Found on your local network and played to directly. No Sonos account is needed. Optionally connect a Sonos account so the speaker lowers and then resumes whatever it was playing. |
| AirPlay speakers | Appear in the roster; route your iPhone to one with the standard iOS picker and Holler talks live through it. |
| Google Cast speakers | Found on your local network and played to directly. |
| Bluetooth speaker | The speaker your iPhone is currently connected to is listed and talked to live. |
All discovery and playback happens over your own Wi-Fi. Speakers that are not on the network you are on are not shown; Holler talks to speakers in the building you are in.
What it is not
- Not a music app. It does not browse, queue, or control playback beyond the announcement.
- Not a chat or messaging app. There is no history and no account.
- Not a smart home hub. It does not manage scenes, routines, or other devices.
Requirements
- iPhone running iOS 26.2 or later.
- A supported speaker on the same Wi-Fi network as the phone.
- Two permissions: microphone, and local network so Holler can find your speakers. Nothing else is asked for.
Availability
Holler is in development and is being tested on real homes and real speakers. It will be released on the App Store for iPhone. Until then this page is the place to watch, and apple@terminuscitytechnology.com is the place to ask.
Privacy in one paragraph
Your voice goes from your phone to the speaker you chose over your own network, and nowhere else. Holler has no accounts. It sends us anonymous usage events and crash reports so we can find failures, tied to a random identifier that is not you. The full privacy policy lists every event.
