Although it is available for anyone but it looks like it’s an advantage for Feedbin users.
It’s called Airshow and it’s a light weight podcast app for iPhone and iPad that you can sync with your Feedbin account at no additional cost. A good blog post describing it here.
Unfortunately it doesn’t offer speed control which is critical for me as I run through a lot of podcasts and can no longer listen to normal speed. Also I’m not sure the UI is to my liking but I’m going to keep this app in the drawer and check back on it’s updates. As a Feedbin subscriber, I like getting more features with my subscription.
