Still needs much development
First of all it is good that this app is free, because at this stage of development, it couldnt be paid.
So far the App only shows the time you slept. Nothing more. It stills require you to click the sleep and wake button.
That is very little if compared to what is available in the market. Fitbit for example recognizes your sleep phase automatically and measures your heart rate during the sleep, which is important to analyze your resting heart rate. Others have silent alarm to wake you up on a lighter sleep phase and some other are able to tell the sleep cycles you had (rem, etc).
Apple watch has potential but unfortunately still doesnt have a good sleep tracker. Hope the next version of this app will hugely improve these points mentioned above.
