Can you shed light on whether there are a common set of algorithms that sleep trackers use or if they are generally all proprietary?

  There are some common algorithms for sleep/wake classification from accelerometer input, but sleep stages algorithms are all proprietary as far as I know.

    Which is another way of saying "no way to verify if they're bullshit or not".

      Not true, anyone could take them to a sleep lab and compare to Polysomnograph-based sleep scoring. I'd love to see a large, independent study on this for a couple of the leading trackers.
