Marco Arment's long-awaited podcast app for iPhone, Overcast, is now available on the iOS App Store. While it won't be luring me away from my precious Pocket Casts anytime soon, it does have some very cool features, namely Smart Speed (which dynamically shortens silences in podcast episodes) and Voice Boost (which normalizes the audio for all shows).

The app itself is free, but a $5 in-app purchase unlocks a bevy of features:

• Cellular downloads
• Variable playback speed
• Smart Speed
• Voice Boost
• Per-podcast effects settings
• One-by-one playback option
• Sleep timer
• Unlimited number of playlists
• Unlimited episodes shown in playlists
