S+ Test

After the test, we can say: it takes a long time to configure device, we had many questions. Pages of application are loading very slowly.

Every time you turn on the Bluetooth, you have to wait about a minute until S+ appears in the list of connected devices. Then a green indicator of gadget lights up, indicating that S+ is connected – but the gadget is yet not found in search.

It is a pity that there is only Bluetooth connection

If you sign out and then sign in, it will take 5 minutes.

When you first set up your account, you need to enter your information – height and weight. By default, you can only specify it in inches and pounds. Selection of kilograms and centimeters is possible only after registration.

Drawbacks of S+

– There is no customer support to ask a question

– Gadget works only if you leave the app open on your phone during the night like Sleep Cycle

night mode S plus

That’s how smartphone screen looks in night mode

– Application is slow, as mentioned above – everything is loading very slowly

– Connection via Wi-Fi would be more convenient, as it implemented in Sense and Aura. Some people don’t like to keep Bluetooth turned on all night.

– There are requirements for gadget location. You should put an empty box on the low bedside table to provide gadget location at the correct height.

– To enable sleep monitoring, you need to make at least three clicks and answer questions from Res Med. Several times it was impossible to set an alarm, we had to set it again – it takes about 10 clicks.

– Polls are detailed. It’s good for sleep analysis, but sometimes it’s annoying. I want to fall asleep as soon as possible, not to answer questions about previous day.

Sometimes polls are annoying

– There is no built-in speaker – relaxing sounds to fall asleep quickly, as well as alarm clock sound through your phone speaker. This is not very convenient.

Pluses of S+ gadget

Schedule of sleep during night: slow sleep, deep sleep, brain rest and wake-up time are considered

+ Relax Daytime function really helps you to relax.

+ FAQ is detailed and has clear answers to many questions

+ Plenty peoples with multiple accounts can use that gadget. But it is unclear how it will work with two people in one bed, we have not checked.

+ Long charging wire


In general, that gadget could be described as a senior brother of Sleep Cycle. But it’s not very convenient to keep the application opened in phone during the night, and use smartphone speakers for alarm signal.

Overall impressions are positive. Technology is working, sleep is determined precisely and detailed, recommendations are helpful. Manufacturer can improve some things by to make application more convenient.

However, it is very functional and useful device made by company, working in the sleep market for over 25 years.

If you want to sleep even better, we recommend you look closely to the Awair – a device for monitoring the air quality in your bedroom.е.{:}
