Today Google released their Blogger App for iOS.
With the Blogger app, you can write a new blog post and publish it immediately or save it as a draft right from your iOS device. You can also open a blog post you’ve been working on from your computer and continue editing it while you’re on-the-go. Your blog posts are automatically synced across devices, so you’ll always have access to the latest version.
The App is free to download from iTunes. You can download the App from here.
