I've been using it on and off for the past few weeks now and I am loving it. The S+ by ResMed is the world's first contactless sleep monitor so you don't need to wear a device such as a Fitbit. The device monitors and analyses your breathing and physical movements while you sleep to give you personalised advice about your sleeping patterns (e.g. it can tell you if you're not getting enough deep sleep and will offer advice). It also measures the light levels in the room and temperature. ResMed have been helping people with sleep conditions such as sleep apnea for 25 years and they are one of the world's leading producers of sleep medical equipment.
It is very quick and easy to set up, the instructions are really easy to follow and I had it set up and ready to use on the first day I received it. The device itself isn't massive, it doesn't make any noise and it is quite sleek. The device connects to your iPhone via bluetooth and their app (it's free from the app store) which is where you add in your personal information and answer their initial questions - this only took a few minutes to complete. There are only four simple stages to set it up, plug it in then download the app and pair the device via bluetooth to your phone and answer the questions - then start!
The app shows a history of your sleep analysis on the days you have used it, I don't use it everyday as it needs your phone to be charging and switched on throughout the night and I don't like to do that all of the time (which is really my only main negative about the device). Before you sleep, you open the app, pair with the S+ and answer a few very quick questions about how you are that day (stress levels etc) and at the bottom of that screen it shows a moving line showing your breathing and movements at that time which is amazing - you do have to make sure the device is properly positioned facing your chest or it won't be accurate but it's easy to make sure it's positioned correctly as you will be able to see your breathing on the moving line as your chest rises and falls; also you can tilt the box so it is pointing directly at your chest.
It has other features that can help such as 'mind clear' were you can clear your mind of things you need to remember for the next day by recording your voice saying whatever you need to remember. Also it has 'relax to sleep' which is designed to produce rhythmic sounds to match your breathing, gradually slowing down to help your fall asleep more easily which I haven't fully tried yet but I need to! Lastly, it has 'smart alarm' which will wake you up during a light sleep stage at a time of your choosing within a 30 minute slot so you will wake up feeling more refreshed compared to waking up from a deep sleep stage.
Overall, I'm so happy with the S+ by ResMed as it's interesting and useful to see my sleep analysis as well as all of the little notifications and advice to help me sleep better - I've used some of the advice but not all of it yet and that's the point with these devices, they can give you tips and analyse your sleep stages but if you don't act on the advice, you won't see any benefit. It's really easy to use, it looks surprisingly nice and sleek and even though it can lose connectivity sometimes, mostly it's really reliable. You also receive a weekly sleep report via email. My only main negative is that my phone has to be switched on and charging all night which I don't really like to do but other than that it's a fantastic and useful device. I think it would make an interesting and very unique gift, if you know someone who has trouble sleeping. Overall rating: ★★★★☆, 4/5.
