Very of accesses, the application does what it to do: monitoring and analysis of sleep quality, smart alarm clock. From that side, although I have a complaint about the sensitivity sometimes a bit random sensor, it works well and that's the main thing.
Then SaA has two additional functions to improve sleep: "The anti-snoring" and "lucid dream". Two certainly smart features that seem relevant at first but can outskirts vites become painful, they have a habit of being triggered totally at random. Involved again the random sensor sensitivity.
Finally, and this is the whole point of SaA, history of sleep, with graphics and diagrams strength to visualize and evaluate our sleep quality. The application even allows to advise us on the best practices for sleep. It can however be a little too fussy: it personally advised me to sleep at least nine hours!
However, was quick to lose that throughout these patterns and details, the better then being to visit the official website of the application on which one can find all the explanations to understand the meaning [sites.google.com/ Site / sleepasandroid / doc /].
4 star rating I therefore, a less sensitivity to the issue.
Finally, and as I say in the title, Sleep as Android is not everything. A healthy lifestyle and also needed to sleep well and have a restful sleep. Some reading not being wrong, I advise this document [ecapnantes.fr/documents/Gerer_et_Optimiser_son_Sommeil.pdf].
