Raw Bio Signals Support

How can I help?

Bugs and feature ideas go to the public tracker on GitHub. Issues there are visible to everyone, which means you can check whether something is already known and follow it until it is fixed.

Anything private - or something you would rather not post publicly - by email. I read everything myself.

Common questions

  • Can I try it without a sensor?

    Yes. On the Record tab, tap "Demo recording". Simulated sensors run through the same pipeline, so you see the cockpit, the recording, the raw viewer and the export without owning anything.

  • My sensor does not show up.

    Check that Bluetooth is on, that the sensor is not still connected to another app or phone, and that it is close by. The Record tab lists everything in range and has a refresh button. Some sensors only advertise once they are worn or moistened.

  • Where do my recordings go?

    Onto your iPhone, and nowhere else until you say so. Under More > Export you can add destinations - iCloud Drive, a folder in the Files app, an S3-compatible bucket or a WebDAV server - and each finished recording is delivered to every one you enabled. You can also share a single .zip from a recording's detail screen.

  • What is in the export bundle?

    One CSV per stream (gzipped), EDF+ for EEG, a manifest.json describing every device, channel and sample rate, notes, and a self-contained HTML page you can open offline.

  • How do I open the live dashboard on my laptop?

    Start a live session on the Live tab. The header then shows a http:// address - type it into any browser on the same Wi-Fi. The page also carries copy-paste snippets for reading the same stream from your own code.

  • How much space does a night use?

    That depends on which sensors are running - a full night of EEG plus ECG is a few hundred megabytes. More > Storage shows what is on the device and lets you delete raw data per recording. Nothing is ever deleted automatically.

  • Does it analyse my sleep?

    No. It records signals and shows them; it does not interpret them, score them or detect anything. What you do with the raw data afterwards is up to you.
