There is a lot of work involved in managing a blog and if you have multiple accounts and platforms it can become tiresome. A new app called Posts helps to manage the process and can even be used to create a new blog. The app is for iPad and is at the more expensive end of the app spectrum at $10.49 but does have a lot of nifty features. Posts can be used with Blogger and Wordpress and you can add multiple accounts to your profile.
You have access to the majority of functions you'd have access to when using a web interface such as inserting links, images and general formatting. There is also the ability to swap to HTML if you happen to be handy with code.
You can view the comments on each post as well as approve, mark them as spam or delete. There is also the ability to respond to comments allowing you to manage even more aspects of your blog through the app.
Offline access means you don't need to be connected to the Internet to draft posts, edit existing posts or manage comments. Any changes will be saved to your outbox and uploaded the next time you're online.
I've been using the app for the last few days and I've found it to be very simple to use. As with all apps over time they'll add more functionality and features allowing you to do everything you need to manage your blog from your iPad wherever you are.
