MyChron analysis

MyChron data analysis software, in your browser

LapViz Studio is a free data analysis software for the AiM MyChron 5 and MyChron 6: your .xrk and .xrz files open in the browser of a PC, a Mac or a Chromebook. Compare your laps, read the revs and the temperatures, then replay the session in 3D on the satellite view of the circuit. No account, nothing to install.

Frequently asked questions

What is the best free software to analyse MyChron data?

Race Studio 3, from AiM, is free but runs on Windows only. LapViz Studio is a free alternative for the analysis that runs in any browser, a Mac included: lap overlay, delta, channels, sectors and a 3D replay of the session.

How do I open an XRK file without Race Studio, on a Mac?

Open LapViz Studio in Safari, Chrome, Edge or Firefox and drop the .xrk file: it is read in the browser, nothing is installed. Race Studio 3, on a Windows PC, is still needed to download the files from the MyChron.

Which MyChron models are supported?

The MyChron 5 and MyChron 6, and the other AiM loggers that record .xrk or .xrz files. The older .drk files are converted by LapViz when you open or import them.

Are my MyChron files uploaded?

Not by the Studio: the file is read on your computer. The 3D replay converts the file on the LapViz server to replay it, without keeping it. A file is only stored when you import it into your account.

Can I compare my MyChron with the Alfano or the Unipro of a friend?

Yes. The Studio overlays the laps of files of different brands, and the leaderboards of the circuits gather every laptimer.

Why are some lap times different from the MyChron?

The laps of the MyChron are kept as they are. On a circuit known by LapViz, the laps are also calculated from the GPS for the leaderboards: these can differ by a few hundredths.

Is it free?

Yes. The Studio and the 3D replay are free and work without an account; the LapViz account is free too.
