Snail Sleep is a free APP based on user's sleep behavior analysis, which can be used to record sleep situation and understand sleep efficiency and quality.

The recognition algorithm of snail sleep has been tested and compared by a large number of professional sleep laboratories, and compared with the sleep data of professional EEG and ECG sleep monitoring equipment. For different types of devices such as iPhone 4, 4S, 5, 5S, 6 and 6Plus, the sleep algorithm is optimized to ensure the accuracy of the sleep algorithm.
