The most frustrating part of the "connected kitchen" has to do with the apps themselves. Appliances look sleek with no buttons and knobs, but those are very effective ways to turn things on and off and adjust settings. If you have to control your cooking device with an app, you pay for the perceived convenience with your time. For example, if you want to use an app to adjust the temperature of an appliance, you have to (1) grab your phone, (2) face/thumb/passcode your way in, (3) ignore the text messages and push notifications and 4) ignore the news, (5) remember why you pulled out your phone, (6) swipe to (6.5) open the app, (7) swipe to adjust the temperature, and (8) try not to wonder what will happen to your buttonless product if the Kickstarter-backed company that makes it goes under and stops updating the app. The old-fashioned way? Twist the knob on the appliance itself and get on with your dinner.
