Radiolab has consistently been among the most popular podcasts on iTunes for years, yet the WNYC-produced program is only now getting around to releasing its first mobile app. Thankfully the just-launched Radiolab for iOS and Android ($2.99) winds up being much more than a mere companion app for listeners, as it offers a comprehensive, feature-rich experience that shouldn't be missed by fans of the show. There's a wealth of content here, with every full-length episode, short, and video produced since Radiolab's debut available for your perusal. To complement this, the app also integrates a "Read" section that compiles blog posts and updates from the show's website

What's more, you're given the opportunity to contribute directly to future episodes. The "Make" area of the app lists requests from the production staff for various audio recordings and photos — right now they're looking for "wild cheering" and photos of your favorite color, for instance. Users can record clips with the built-in mic on their iOS / Android device and upload that content to Radiolab via Soundcloud. Similarly, you can also give recording the podcast's credits a try if the idea of hearing your own voice on a future episode excites you.

In terms of using the app itself, it's immediately clear that developers PRX (with design credits attributed to 1 Trick Pony) put tremendous work into Radiolab. The app combines a swipe-based navigation scheme with a number of fluid transitions that make exploring its various sections genuinely fun and intuitive. The video below should provide a sense of how it all comes together. We're seeing plenty of five-star user reviews for Radiolab, suggesting that podcast fans needn't be too concerned with coughing up the $2.99 asking price.
