Bio-Smart alarm monitors user's sleep cycle and tries to wake them up around the time the set the alarm but do it during the light phases of their sleep. This in turn should make them feel well rested. Power Nap Alarm monitors the sleep activity while the user is taking a short nap and tries not to let the user slip into deeper phases of sleep so they do not wake up more tired. Doze-off Alert is designed mainly for drivers. In this mode, the device monitors drowsiness of the user and alarms them when their fatigue increases to avoid a potential microsleep and car accident. Sleep Enhancer uses an additional wired gel electrode that the user adhesively attached to the inside of their palm. The weak electrical current stimulating the palm is advertised to enhance the sleep quality of the wearer. Hear Rhythm Monitor records the heart rate of the user and can warn them in case of arrhythmia or high heart rate. Sleep and Activity Tracker uses all sensors to record and track data about the user's health. It provides information on "sleep patterns, daytime activity and concentration levels" of the user and makes this information available in the Sleepman smartphone/PC app. Panic Alarm is a feature that can be pre-programmed to send an emergency message or dial an emergency number should the user run into an accident. This feature requires pairing up the device with a smartphone. InsomniZap is a computer game that uses the biological feedback recorded by the device to ease the user into sleep. It is mainly focused on children but the company states that all can benefit from it.
