I am trying to get data from this type of scale https://acaia.co/products/pearl. It does not show up under discover-able Bluetooth devices on a computer or phone, but it does have an app which it connects to automatically when turned on; the app can then display the weight in real time. This is my first time working with Bluetooth devices and am unsure as to how it is connecting to the app without showing up on other devices. Any information as to what is going on and possibly steps in the right direction would be greatly appreciated.

What you need to do is do some bluetooth sniffing to find out how the device is communicating with the phone. Here is a good article on doing that : http://nilhcem.com/iot/reverse-engineering-simple-bluetooth-devices
