lark™ | Design & Technology
Using actigraphy, lark tracks millions of micromovements every minute in order to calculate how long and how well you've slept each night. Actigraph units use accelerometers and timers to track your sleep patterns. Wear it on your non-dominant wrist for best results.
Dynamic vibration technology was designed with top sleep experts for a wake up experience that feels like you woke up naturally. lark’s gentle vibration can reduce heart rate variability, stress levels, and blood pressure spikes, all of which are known to cause that awful groggy feeling in the morning.
