    Data but little information

    • Written by Richard S from GLYNDON

    I’ve used the device for two weeks and nighty results vary considerably. I’ll assume the accuracy of the sensor, but there is no way to evaluate the data collected. Showing only heartbeat and breathing is not sufficient to determine duration of light, deep or REM sleep cycles. Compared to the FitBit info screen, this is pretty minimal. And their Tips are not much help, you’ll do better researching on line. I’ll look forward to upgrades.
