SD Card Viewer

Two ways in: pick the SD card folder to browse audio & accelerometer recordings in place (Chrome/Edge), or drop a single METADATA.CSV for the lightweight sensor-only view.

Your data stays on your computer
None of the SD card contents — audio, accelerometer, GPS, status logs, anything — is sent to a server. Files are read directly off the card by your browser; parsing, stitching, playback, gain, and the bundle/download builders all run locally in this tab. The page works offline once it's loaded. The only outbound network call is a timezone lookup from the first GPS coordinate, which sends just the lat/lon to timeapi.io and nothing else.
Experimental tool
This viewer is under active development. Timestamps, fragmentation, the synced bundle, the boost/declick filters, and the accelerometer unit conversion can all be wrong in edge cases we haven't seen yet. If anything looks off — or you'd like a feature added — please tell the team via support so we can fix it. Including the device ID and the rough time of the recording you were looking at makes diagnosis much faster.

Drop METADATA.CSV here

Or use a button below.

Folder access needs Chrome or Edge. In other browsers, use the METADATA.CSV path — that file is read locally by your browser too and never uploaded.
