Nokia Sleep offers sleep cycles analysis (deep, light and REM), heart rate tracking and snore detection. Easy one-time setup and automatic sync to the Health Mate app via Wi-Fi. Also features IFTTT integration for scenarios such as dimming lights when you go to bed, or turning up your thermostat when you get up.
Every day, wake to a Sleep Score in the Nokia Heath Mate app that shows you if your night was restorative. In the app you can also take advantage of the Sleep Smarter program so you can improve your nights over time.

May 2017 - Apple acquires an app and sleep monitoring device called Beddit.
The Beddit 3 Sleep Monitor automatically tracks your sleep and works with the Beddit app on your iPhone or iPad to help you achieve better sleep. Unlike activity trackers, Beddit is completely ambient so there’s no need to wear or charge it. The thin, flexible and soft sensor is unnoticeable when placed under the sheet on top of the mattress. It senses and automatically begins tracking when you lie down on the bed — collecting and analysing sleep-related data such as sleep time and efficiency, heart rate, respiration, temperature, movement, snoring, room temperature and room humidity.
Understand your sleep patterns better The Beddit app delivers personalised insights and customisable sleep coaching to help you improve your sleep. In addition, the Beddit Smart Alarm provides the most accurate method of detecting the optimal time to awaken you from sleep. How it works Beddit technology is based upon a scientific principle known as ballistocardiography (BCG), an unobtrusive, non-invasive technique for measuring the mechanical activity of the heart, lungs and other body functions. Each time the heart beats, the acceleration of blood through the circulatory system generates a mechanical impulse that can be measured and analysed. Throughout the night, Beddit tracks each individual heartbeat and respiration cycle. Beddit’s advanced analysis and machine-learning algorithms adapt differently to each body type and provide detailed sleep data.
