That depends on how much you're into smart appliances. The most useful thing is the notifications - you'll be notified if the doors are left open for more than 10 minutes, and if something does go wrong, you should get a heads up. It's also helpful in tracking your refrigerator's power consumption. It will track how many times you open and close the doors, which is useful in terms of seeing how this impacts power levels. In short, if you like to be informed on how well your appliances are working for you, you'll enjoy using this app.
