The playbook
How GameSound works
No app store, no login, no server in the middle. Your browser watches a public scoreboard and sounds the horn when a team you follow scores. Here is the whole play, start to finish.
Four steps to the horn
-
Pick teams or games
Head to Teams and tap the teams you care about, or tap Follow on any game card on the home page. Picks save in this browser instantly.
-
Arm the sound
Tap Sound: OFF - tap to arm on the home page. Browsers will not play audio until you interact with the page, so this one tap unlocks the horn. Use Test the horn to hear it.
-
Keep the screen on
Turn on Keep screen awake so your phone does not go dark mid-drive. Optionally turn on Alerts to get a browser notification alongside the sound.

Hear the horn
When a followed team scores, a banner flashes in that team's colors with the play type and score, and the horn sounds. Touchdown, field goal, extra point, two-point conversion, safety: each one is called.
Where the scores come from
Scores come from ESPN's public scoreboard feed, and your browser reads it directly. GameSound has no server of its own, so nothing about you passes through us. While a game you follow is live, the feed is checked every 10 seconds; between games it slows down to save battery, and it pauses entirely when the tab is hidden.
A score is detected when a team's points go up between two checks: 6 is a touchdown, 3 a field goal, 1 an extra point, 2 a two-point conversion or a safety. If the feed corrects a score downward, the card updates quietly with no sound.
Background and locked-phone alerts are not supported yet. Alerts only fire while this page is open in the foreground. Locked-phone alerts need a server to do the watching for you, and that is on the roadmap.
Install it like an app
GameSound is a progressive web app. Installing it puts an icon on your home screen, opens it full-screen without browser chrome, and caches the app shell so it loads instantly on game day.
iPhone and iPad
In Safari, tap the Share button, choose Add to Home Screen, then tap Add. Open GameSound from the new icon. On iOS, the Alerts toggle only works from the installed app, and the ringer switch controls the horn.
Android
In Chrome, tap Install app in the controls when it appears, or open the browser menu and choose Install app or Add to Home screen.
Desktop
In Chrome or Edge, click the install icon at the right end of the address bar, or use the Install app button in the controls. It opens in its own window.
FAQ
Does GameSound work when my phone is locked or the app is in the background?
Not yet. Alerts only fire while the page is open and in the foreground. Turn on Keep screen awake so the display stays lit during the game. Locked-phone and background alerts need a server and are on the roadmap.
Why do I have to tap to arm the sound?
Browsers refuse to play audio until you interact with the page. One tap on the Sound button unlocks playback for the rest of your visit. If a reload benches it, tap once more to re-arm.
How fast do the alerts arrive?
During a live game the scoreboard is checked every 10 seconds, so most alerts land within 10 to 15 seconds of the score posting to the public feed.
Is GameSound free, and do I need an account?
Yes and no. GameSound is free, there are no accounts or sign-ups, and nothing is stored on a server. Your picks live only in this browser.
What is the difference between following a team and following a game?
Following a team covers every game that team plays, all season long. Following a game covers only that one matchup and drops off your list once it ends.
Which sports and leagues are supported?
NFL only for now. Other leagues are on the roadmap and will use the same pick-and-listen flow.
