This is a really intriguing idea and it does what it claims well
I hate that I need to explicitly tell the app I'm going to bed. Using it disables 'Hey Siri' functionality which I use to control HomeKit.
The Beddit 2 product has a lot of potential but it's been purchased by Apple and since then largely ignored. I think there is a great opportunity for a company like Casper or Leesa to make a competing product and sell it alongside their mattresses but it doesn't seem like something Apple is interested in directly.John Morrison has used this product for one month.
