I would agree with the reviews. I've owned the Vivosmart 4 for about 2 months. Have worn it almost that entire time. It cannot detect if you fall asleep for let's say a nap in the afternoon. You tell the device when your typical bedtime and wake-up times are and it seems to be looking for sleep during that time. Within that period it is good at picking up my sleep period. The sleep function is OK...not great. Here's an example: I woke up one night around 1:30 am. Got out of bed and it accurately recorded that wake-up time. However, I fell back asleep around 3 am on the couch and it did not detect that second sleep period.
Sorry, there was a problem. Please try again later.
