GooTasks has been updated, to Version 4.0. One of the big additions is iPad support.
Here’s the App Store bio for the app:
GooTasks™ is the only multiple-account iPhone app that can quickly and easily synchronize your Google Tasks™ with your iPhone, iPad or iPod Touch. GooTasks™ can also be used without an Internet connection. The changes will be recorded and sent to Google™ the next time you connect.
You can find GooTasks in the App Store now, and it’s a free app.
