I really like Gee Apps. It seems to me the best of the iPhone apps for managing Google Tasks, especially if you want offline functionality.
I bought the pro version because I have a Google Apps account for work. But I also have a regular gmail account and tasks that I am organizing there, not related to my work. I would LOVE it if I could manage multiple gTasks accounts, both gApps and regular versions, through the pro version of your Gee Tasks app.
As workaround I actually also purchased the standard version in order to have a separate app for my regular google Tasks account. I could live with this (though I'd really prefer multiple accounts through one interface)—but the new version of iTunes is not letting me install the standard version of Gee Tasks in addition to the Pro version. I think this is a problem with iTunes, because there are other apps that the latest iTunes is not updating and throwing an error instead.
Thanks for developing this great iPhone app.
