The short answer is: No.
Although Billy will work without a smartphone in the home, there are still some advantages to having one.
Firstly, you and your family will need a smartphone to access the Billy app, which is where you will see key insights and receive timely alerts.
We also use technology in your phone to know whether you are home or not. For example, we don't want to notify your family that you've missed a meal if you've gone out for lunch with friends.
If you choose not to use a smartphone, that's ok! Just let us know so we can help with an alternative way to know if you are home or not.
Billy will work on any iPhone running iOS 9.0 or above, or any Android phone with Android 5.1 or above.
