If you leave the range of Bluetooth (15m, 50ft) and your smartphone is connected to the internet, you can activate the Remote alerts function of the App and the Smartphone will turn into an internet bridge.  This way you can monitor the temperature, the time, the cooking steps and the alerts on all devices whilst being connected to the internet. (iOS, Android and Windows).

You may do the shopping, go for a walk with your dog and still keep an eye on the stove or oven.

Remote alerts everywhere
