@Civuck There is nothing magic in sleep monitor, It is just based on the noise intensity lesser the noise good will the sleep results, it detects the noise you are making while you are sleeping like when you've had a good sleep then you will not snor or change position frequently this means that no noise would be there, sleep monitor application can't working in the place which is very much noisy and as far as the unique results are concerned they are not accurate it works on the approximation.
