GT7 Datalogger records the telemetry your PlayStation sends while you drive Gran Turismo 7 — speed, pedals, gear, revs and about 28 channels in all, sixty times a second. It splits the stream into laps and shows them live and lap by lap in your browser, with lap comparison, a spoken race engineer and maps of every circuit. It runs on your own computer and needs no account.
MIT licence. Every download is built by GitHub Actions from the public source. Older versions and release candidates are on the releases page.
The desktop app runs the same server a Docker install runs, and opens the dashboard in your own browser at http://127.0.0.1:8000/. On macOS and Windows it adds an icon to the menu bar or the notification area. The first start walks you through finding your PlayStation.
macOS 13 or later, on Apple silicon (M1 and newer).
GT7-Datalogger-macOS-arm64.dmg
Open the .dmg and drag GT7 Datalogger to Applications. It is signed with an Apple Developer ID and notarized by Apple, so macOS asks once whether to open it.
On an Intel Mac, use Docker.
Windows 10 or 11, 64-bit. Windows on Arm runs it under emulation.
GT7-Datalogger-Windows-x64-Setup.exe
Run Setup, then start GT7 Datalogger from the Start menu. Before it installs, Setup asks about each of the three things the app fetches on its own. The portable .zip needs no install: unzip it anywhere and run gt7-datalogger.exe.
Free code signing provided by SignPath.io, certificate by SignPath Foundation (approval pending). Until then the Windows files are unsigned and SmartScreen warns about them: choose More info, then Run anyway. See the code signing policy.
x86_64: Ubuntu 22.04+, Debian 12+, Fedora, RHEL 8+.
GT7-Datalogger-Linux-x86_64.AppImage
Make it executable and run it: chmod +x, then ./GT7-Datalogger-Linux-x86_64.AppImage. The .tar.gz is the same app as a plain folder, and needs no FUSE.
Linux has no tray icon yet. Stop it from Settings › About in the dashboard.
The same app as one container, for any machine Docker runs on — an Intel Mac, a NAS, a Raspberry Pi 4, 5 or Zero 2 W. Images for amd64 and arm64 are on GitHub’s container registry. Open http://<that machine>:8000/ once it’s running.

The GT7 Datalogger phone app records straight from your PlayStation, or follows a datalogger on your network, with the live dash, Analysis and the Race Engineer built in. The iPhone and iPad version is in the App Store; the Android version is on its way.
Free, in the App Store.
Needs iOS or iPadOS 15 or later. Open the link on the iPhone or iPad itself, or search the App Store for GT7 Datalogger.
If something goes wrong, the support page says how to tell me.
Coming soon.
The Android app is still being built and isn’t on Google Play yet. Until it is, an Android phone or tablet can use the dashboard in its browser.
Nothing to install.
A phone or tablet on the same Wi-Fi opens the dashboard in its browser: the full dashboard, the live dash at /dash, or the Race Engineer at /engineer.
In the desktop app, turn on Let my phone/tablet connect, then scan the QR code in Settings › Phone app.
Each release carries SHA256SUMS.txt, and a GitHub build provenance attestation ties every file to the workflow run and the commit that built it. From 1.0.1, the Linux files also have a detached signature (.asc) beside them.

Until Windows signing is approved, a release’s Windows files are unsigned and its release notes say so.What the app sends, where to, and how to turn each request off is on the desktop app’s privacy page. The installer asks about each request before the app first runs.
The app bundles Python and its open-source dependencies, pinned by hash in the repository. They are signed as part of the app. The full policy is in the documentation.
