I have been looking for a app or a way to have the weather show up on the calendar through the iPad.
If you log into google and use the calendar in there, you can have a four day forecast shown under the days. I like this as it makes it a little easier to book clients and such to get their toys cleaned while having a real time weather report.
I have seen plenty of people having problems just getting the sync to work, which I have had no problems with at all, it has worked flawlessly since I first open my iPad a year ago. I just can not for some unknown reason find a way to get the weather to show on the iPad calendar with the google sync.
