From your PS5 to your ears

GT7 broadcasts telemetry on your home network — position, speed, throttle, brake, sixty times a second. GhostChaser listens to that feed from your iPhone and turns a curated reference lap into something you can drive against: tones, beeps and live traces. Nothing is installed on the PlayStation. Nothing is modified. Here's the whole path.

Setup is five minutes

1. Install GhostChaser on your iPhone and put the phone on the same home network as the PS5. Ordinary Wi-Fi is all it takes.
2. Let it find the PS5. The app scans for the console and asks it for the telemetry feed — the same one that powers motion rigs and dashboard apps. If your network hides the console, type its IP address once in settings.
3. Drive. Qualifying, a race, practice laps — the moment telemetry arrives, the instruments are live.

That's the list. No capture card, no PC, no overlay — and no account: there's nothing to sign up for.

In the car — by ear

Your eyes are on the TV, so the coaching reaches you through your ears.

• Tones that encode pedal pressure as pitch. Each ear is yours to assign: the reference lap's brake in the right, your own brake in the left is the default. Where a faster lap brakes is something you hear rather than read, and the mismatch between your ears is the correction. Throttle works the same way, and there are twenty tone presets with a preview sweep.
• Two beeps counting you in — one about two seconds from the reference's brake point, one about a second out, timed at the speed you're actually carrying. Carry more speed and they fire earlier.

Nothing talks to you. A tone you can learn the rhythm of is an instrument. A voice mid-corner is not.

On the screen

Two panels, brake and throttle, drawn corner by corner: the reference lap's trace for the corner you're in, a cursor riding your position through it, and your own trace laid over the reference's. Alongside the trace, the numbers that matter for that corner — entry, apex and exit speed, yours against the reference's, and the gear each of you is in. A status bar names the corner and keeps a running delta: red when the lap is slipping away, green when you're up.

Between laps you can flip either panel to a rolling scope view (the last three seconds of pedal work, gear changes marked) or tap a panel to fill the screen with it. Nothing on it demands a glance mid-corner. It waits until you look down.

Every Monday — the reference laps

GT7's three Daily Races rotate on Monday, and the app follows the rotation: each week's reference laps are curated for those races — a real lap by a named driver, in a car eligible for that race, not a generic ideal. Where a race allows several cars, references are curated per car. Open the app and the week is already there; this week's races are on the site too.

What it doesn't do — on purpose, and honestly

• No reference, no coaching. On a track outside this week's rotation the app stays quiet rather than coaching against a made-up baseline.
• GT7 provides no sector times, so we don't offer them — the running delta against the reference is measured continuously from the telemetry instead.
• Nothing speaks. Tones and beeps only. If an app talking over your racing sounds awful to you, we agree.
