@KaraLG84 A smart stack pretty much watches what widgets in the stack you commonly check at certain times during the day. So for example if you’re working and you always check your public transport app at a particular time every day, or more to the point check the public transport app widget in the stack at a certain time every weekday, it would learn that and start to put it already on that by the time you look at it. If you don’t have anything regular that you do, it makes it less likely that it will know what to put up in front of you.
