Somnology – Improving Sleep from Somnology on Youtube.
Using real-time mobile technology Somnology provides the user immediate insight into and relief of their sleep disruptions in order to gain a productive, restful sleep.
Somnology, Inc. offers a family of devices, mobile and desktop applications, and clinical services all designed and developed by a practicing sleep specialist to provide meaningful information and resolve a user’s sleep disturbance(s). These sleep tracking products are designed for those seeking new information about their sleep, as well as for those who want to track their sleep patterns. The Plex sleep scanner and SomnologyMobileDoc are useful for BOTH insomnia and possible abnormal breathing patterns.

Mission Statement

Reasons why monitoring your sleep patterns is important (and these are just a handful!):

We don’t sleep the same way every night,
so a single snapshot of your sleep may miss important information.
If you were trying a program such as weight loss or side-sleeping,
you could track improvements in your sleep patterns.
If you decided to keep a regular schedule and make other changes in your bedtime routine,
you could track your improvement in sleep efficiency and continuity.
If your health status changed or you were started on new medications,
you could monitor yourself for changes in sleep patterns.
If you were already on a program for sleep such as CPAP or a dental device,
you could check for stability over time.


Manage your sleep disturbance with a personalized sleep assistant at your fingertips.

SomnologyMobileDoc was created to help people with sleep issues such as snoring and insomnia. Many people suffer from these problems but may not have access to the help that they need. SomnologyMobileDoc asks questions about your sleep and, based on your answers, determines whether you show signs or symptoms of common sleep disorders.
