PITLENS analyses the data from a range of loggers and has finished reports ready two minutes later, for drivers, engineers and the next session. Almost every number in a report takes you to the data behind it, the tyre pressures for the next stint are calculated, and you can watch your ideal lap as onboard video.

Load the files Pick one or more logger files from the car and load them into an event. They are the basis for every report and every measurement.

Pick the circuit Set the entry and exit points of the corners for the measurements, or use the track maps PITLENS builds on its own.

Define the car Enter reference values such as rpm targets for the car you're running. You do that once per car.

Pick the laps Use the automatic selection by gap to the fastest lap, or pick laps by hand.

Build the reports In under two minutes you have reports tailored to each driver that show their biggest, recurring mistakes.

Jump into the data Almost every number in the report is backed by data, and one click takes you to the data behind it.

In the Explorer Compare the relevant channels across one or more laps, have the best possible lap built from the corners, and dig deeper into the data.

Video alongside Show the matching onboard next to the data and compare where time is lost. Or have the fastest corners from all laps cut into one video, so every driver sees what the optimal lap would look like.

Onboard with HUD Put speed, gear, pedals, lap time and track map from the data file over your onboard and render it as a video file. Six layouts are included, and four of them alternate here. You can build your own too.

Tyre pressures and wear Get projections for the optimal tyre pressure and the expected wear, for a long stint or for qualifying.

Rain radar The Weather tab tells you in one line when the rain reaches the track or stops. Below it you find the rain over time and the radar map with playback.

Three things PITLENS doesn't do

Upload your data

PITLENS runs locally on your machine and normally needs no internet. Only the chat, the rain radar and the updates need a connection. The team's tablets and phones read along over a local Wi-Fi and only see the current event there. So your data stays safe and with you alone.

Make things up

If a channel is missing or no recurring pattern shows up, that's exactly what the report says. PITLENS currently uses no AI for the analysis in the reports.

Only look at the fastest lap

PITLENS analyses every lap of the weekend, not just the fastest one. That makes patterns in a driver's style visible, and the data from earlier weekends is there for comparison.

Who is behind it

PITLENS is not built at a desk but at the track. Behind it are two people from the paddock who work with the data themselves.

Niklas Krause

Development and data analysis

Niklas builds PITLENS. Every analysis in the reports was checked against real data from practice and races before it went into the app.

Stefan Kissling

Track and teams

Stefan brings the view from the pit box. He runs PITLENS on race weekends and makes sure every report answers the questions drivers and teams really ask.

Common questions

Can I use PITLENS on my own as a driver?

Yes. All you need is the file from the data logger and a Windows laptop.

Which loggers and files does PITLENS read?

MoTeC .ld, the text export from Bosch WinDarab, the Cosworth offload .pds, AiM and VBOX .vbo. PITLENS uses the channels the data contains.

Do I need internet in the paddock?

No. PITLENS runs locally on your Windows laptop and does all the maths there. You only need internet for the chat, the rain radar and for updates.

Does PITLENS show when it will rain at the track?

Yes. The Weather tab shows a rain radar for the track and tells you in one line when the rain arrives or stops, for example “Rain in about 20 min”. The data comes from the radar of Deutscher Wetterdienst. So the rain radar works in Germany and a little beyond its borders, and it needs an internet connection.

Where does my data go?

Logger files, reports and driver names stay on your machine. Tablets on the team Wi-Fi can view the reports, optionally behind an access code, and only see the current event. If you use the chat, your question and the values PITLENS works out for it go to the AI provider you connect in the settings. The logger files themselves never leave your machine.

Do I still need an engineer?

The reports are built in PITLENS and already show a great many mistakes. For deeper analysis an engineer still helps. If your team has one, PITLENS gives them deeper information, and faster, because it fits into their workflow.

What does PITLENS cost?

During the beta, PITLENS is free. From 2027 there will be licences in different sizes, from a single driver to a team with many cars. We'll announce prices before launch.

Is PITLENS available in English?

Yes. The app and the reports come in English and German, with metric or imperial units.
