You can either just turn it on and play it by ear, set it for a set time to cook for or set a 'finish by' time. You can also control it via the app on your phone or iPad. Apparently - I haven’t tried that yet. The last two will give an alarm at the end of the time and also ask if you want to leave it in longer (in case you got the timing wrong and the food isn’t cooked properly).So when it's says your program is complete, how does it know. Have you entered a time manually somewhere.
Does the oven still have an old fashioned timer/ringer?
