Google on Tuesday added support for the iPad and iPod touch to its Google Voice iPhone app. The update lets users access all the features of the Google Voice app, like sending a receiving free texts, across the three devices.

The upgrade won't let you turn your iPod or iPad into a phone, but you can use it to initiate calls, Google said.

"We call this feature Click2Call. Simply click any 'Call' button in the Google Voice app on your iPod or iPad and then select which of your phones you want to ring," Marcus Foster, a Google product manager, wrote in a blog post. "Google Voice will call your phone and then connect your call."

Google also made some general improvements to the overall app. When you enable push notifications, Google will now automatically disable text forwarding, so you won't receive multiple notifications. Those who don't want to be interuppted can also send users straight to voicemail by selecting the "Do not disturb" option in the Settings tab. Google also added a Contacts button to the "Dialer" tab, which will make it easier to place calls from the address book.

Google also made it faster to send a text; users no longer have to press the "OK" button to send a message. To archive or delete a message, meanwhile, tap and hold.

The Google Voice app is available to download from the Apple App Store now for iPhones, iPads, or iPod touches with iOS 3.1 or later and a valid Google Voice account. At this point, it's only available in the U.S.

Google added the Google Voice iPhone app to the App Store last month.
