Download sessions from your MyChron over Wi-Fi

LapperSnapper talks to your MyChron directly over its own Wi-Fi network. No laptop, no Race Studio, no memory card.

Before you start

• Turn the MyChron on and enable its Wi-Fi (check your MyChron manual for where this lives on your model).
• Stay near the logger — its Wi-Fi range is short.
• Use the LapperSnapper app on your iPhone or Android phone. The web app can't join a logger's Wi-Fi.

Steps

1. On your phone, open Settings → Wi-Fi and join the logger's network. It's named AiM-… followed by your device identifier.
2. If your phone warns that this network has "no internet", keep the connection anyway — that's expected. The MyChron isn't an internet router. On iPhone specifically: turn Cellular Data off before connecting — iOS can silently reroute traffic to cellular mid-download with no prompt shown, which drops the connection.
3. Open LapperSnapper, go to the Import tab, and tap MyChron.
4. Tap Scan for devices. Your logger appears in a list — tap it to see its sessions. If the scan finds nothing, Connect manually reaches it by address.
5. Select the sessions you want (or Select all) and tap Download. The app downloads them in turn and shows progress.
6. When they're all in, the app takes you to Sessions, parsed and ready to analyze — including engine channels like RPM and temperatures in the Channels tab.
7. A Track conditions sheet then asks how the track was. Tag it, or tap Not now — see Tag the track state after an import.

If only some sessions make it, the app keeps what downloaded, shows Downloaded X of Y — couldn't fetch the rest with the reason underneath, and leaves the failed sessions selected so Download retries just those.

Your logger is remembered under Your devices on the Import screen, so next time it's one tap. You can give it a friendlier name — see Rename or forget a saved device.

Good to know

MyChron 6 firmware from September 2026 writes its session files differently. Current versions of LapperSnapper read them; older versions can't, so update the app if new sessions stop importing. A few channels the logger records without naming them are rebuilt by the app and marked inferred in the Channels tab.

If the app can't find it
