What are the reviews for the Sleepon Go2Sleep sleep tracker?

The Sleepon Go2Sleep tracker has garnered a mixed reception in terms of reviews. Users appreciate its novel design, which is worn on the finger, offering a less intrusive sleep tracking experience compared to wrist-based or bed-mounted devices. Many have praised its accuracy in monitoring sleep patterns, particularly its ability to track blood oxygen levels throughout the night, which can be a significant indicator of sleep disturbances like sleep apnea. However, some users have reported challenges with the device's app, citing issues such as syncing problems and a learning curve in interpreting the data. The comfort of wearing the device all night is typically highlighted as a plus, but individual preferences may vary. Overall, it seems to offer a useful set of features for those looking to gain deeper insights into their sleep quality, though user experience might be improved with further refinement of its software ecosystem.
