What is second screen behavior?

Second screen behavior is when viewers use a phone or tablet while watching TV or streaming. For Gen Z and Millennials, it’s now a natural extension of the viewing experience.

How common is second screen use among Gen Z and Millennials?

Very common. 85–89% of Gen Z use a mobile device while watching TV, and over 76% of Gen Z and Millennials say they often or always browse the internet on a second device. Smartphones are the dominant second screen, with ownership near universal.

What do people do on their second screens while watching?

Typical activities include checking social media and messages, looking up show-related info, and shopping links tied to what’s on screen.

Why does second screen behavior matter for streaming platforms?

It’s the norm, not the exception. Managed well, it drives deeper engagement, longer watch time, stronger retention, and new monetization opportunities.

How does Sound Dimension’s AiFi use the second screen?

AiFi turns phones into synchronized speakers, integrating them into the sound experience for social listening, surround sound across devices, and immersive group sessions.

How does AiFi improve engagement instead of causing distraction?

By keeping the phone inside the experience: the second screen becomes a sound extension of the story, reinforcing immersion rather than pulling viewers into competing apps.

Can second screen behavior help content go viral?

Yes. Second screens are where conversations happen. Shared listening and synchronized group moments are inherently social, boosting organic sharing and recommendations.

What monetization opportunities does AiFi unlock?

Premium synchronized live events, upsells for group sound experiences, sponsorships and branded events, plus audience intelligence on participation and session behavior.

How does AiFi help reduce churn?

AiFi makes the phone an extension of the platform, not an exit point. Synchronized sound across devices increases watch time, strengthens social bonds, and lowers churn.

What is AiFiTogether, and what does it do?

AiFiTogether is a suite of demo apps that turn ordinary mobile devices into synchronized, spatial sound systems—without extra hardware.

AiFiTogether Music lets you create group listening sessions by syncing multiple phones to play music in harmony.
AiFiTogether Video allows one device to stream video while others join in as surround sound speakers, creating a cinema-like experience on the go.

These apps demonstrate Sound Dimension’s patented audio technology and are built for testing, evaluation, and inspiration.

Can I connect a smart speaker?

Yes! You can bridge and sync various devices, including Bluetooth speakers and popular smart speakers like Sonos, to your mobile “jam” to create an even more powerful, unified sound experience.

Who are these apps for?

These apps are built for potential partners—platform developers, hardware manufacturers, and content creators—who want to explore how spatial sound can enhance their product experience.

Can I integrate this technology into my product?

Yes. These demo apps are just the beginning. If you’re interested in licensing or integration, get in touch to discuss how Sound Dimension can bring spatial audio to your platform or device.

How does “Start a Jam” and “Join a Jam” work?

Our “Jam” system lets users create or join synchronized sound sessions:

Start a Jam: One user initiates a session (as host). This device becomes the anchor for music or video playback.
Join a Jam: Nearby users can connect their devices to the host. Once joined, their devices automatically sync and contribute to the overall audio output.

This turns phones or tablets into a network of speakers that expand the soundstage and spatial dimension of the content being played.

Stream smarter. Sound better.
