Automatic sleep tracker & more

Overall the app is good..
But i want developers to add automatic sleep and wakeup detection so that i don't require to start sleep tracking manually every night before going to bed .. its actually very inconvenient.
Moreover, the apple watch apps show to firstly turn on phone app and select the sleeping hours ..
Instead it should detect automatically our sleep time and wakeup alarm can be set once's in the settings for everyday or for separate days .
Apart from this , i want developers to focus more on apple watch app and make it more independent of iPhone app .. u know nobody like to set sleep hours in two devices .By developing apple watch it will truly become the best sleep tracker app.
I also want the app to tell me about my sleep cycles timing i.e about rem , deep sleep and light sleep (it only shows %age).
This will be more effective if users can see both sleep and heart chats together as they can know in which sleep cycle the heart rate elevated.

Developer Response ,

Hello! Automatic sleep tracking and detection is already in the works and it's going to be available soon. A subsequent update will introduce even more autonomy and depth of information for the Apple Watch. At the moment, a number of restrictions imposed by watchOS and iOS do not allow us to create a completely autonomous app on the Apple Watch, however, we're optimistic that upcoming updates will make that possible. Thank you for your patience and understanding.

Became redundant after update

The app used to work perfectly before in sync with data from apple watch and used to wake you up in light sleep. After the recent updates it has become completely useless. The app can't get real time data from the watch, so it doesn't know when you are in light sleep. The developers say it relies on microphone, but even that is not working for me. Whatever time i set the alarm it just wakes me exactly half an hour before that each and everyday day. There is no smart component. Only thing it does is collect your heart data and give you analysis after you wake up. This thing can be done with the default iOS app bedtime also.

Developer Response ,

Hello! The default iOS app does not perform sleep analysis, audio recordings or automatic sleep tracking to name only a few. From the description of the issue, it seems like the Apple Health permissions have been reset which can be caused by an iOS or Pillow update and it's beyond our control. However, it can easily be fixed by following the instructions in this article: If the issue persists, please contact our support team: To contact support: Open Pillow on your iPhone › Tap on the Settings icon › Select ‘Helpdesk’.
