Tasket is a service that syncs your Google Tasks list with your iOS Reminders list. It performs this magical feat pretty much flawlessly, using a Microsoft Exchange server to do the syncing, and letting you add and remove tasks from pretty much anywhere.
The service, by developer Andrew Dalgleish, is in beta. From a user’s point of view, this seems more due to server scaling than to functionality—it works just great for me. Once you get access (you need to sign up with your e-mail address), you have to add a new Exchange account on your iDevice with your Tasket details. You actually sign in with your Gmail account, and grant Tasket access to tasks and your profile (but nothing more).
You tell this account to sync tasks, and then you’ll see your Google Tasks appear in the Reminders app. You can add and edit tasks from the app, or from the little panel down at the bottom right of your Gmail window.
Why? I use it because I can easily turn my Gmails into reminders, and because, while I like the Reminders app on the Mac, I am more likely to have a Gmail tab open in Safari.
I have a feeling that Tasket is going to be pretty huge, judging by the amount of interest I have seen on the Internet while I was searching for a Reminders/Tasks sync myself. Andrew plans to start charging something in the future, but for now the service is free.
