You can just type "current temperature" in google and it'll give you the weather forecast for the week. At least with google, they already have all your data.
If you're gonna type into Google, "weather" is shorter to type. "temp" even shorter. And on iOS, a weather app + dashboard widget and a single right swipe even faster. And on Android, a weather app + home screen widget and zero action even faster still. And we're back full circle.
