Apple don't just buy apps and leave them as is. There's a purpose behind this. If it was just going to stay as an app they could have left it for sale on the Play Store.
Apple shutting it down totally on Android I feel means something.
Of course, I'm just spitballing here and may be playing in the weeds.
Then again... 🤔
They often shut down apps on android, and they will likely shut it down on iOS as well, and just build it into weather, which is what they are already doing.
