Castamatic is the best app to listen to podcasts on any iOS device. Quickly assemble a custom sequence of shows to listen to or create a smart playlist, and listen to your favorite shows with enhanced audio quality, thanks to Castamatic's machine learning enhanced Auto-leveler DSP algorithm.

A piece of the iPod lives on inside Castamatic. The "On the Go" playlist was originally meant to assemble a new playlist on the iPod if inspiration came while away from the computer, and then sync it to iTunes as soon as user goes back home. This becomes even more useful in Castamatic, where users can pick the episodes they want to listen to in their next listening session and assemble them in a playlist just before leaving. The On the Go playlist will mantain the same order in which the episodes were added, then the user can move and rearrange them manually. As soon as an episode has been completely listened to it will be automatically removed from the On the Go playlist.

A great app with non intrusion email ads


I live this app, it a great podcast player and yes it has ads but they are not that intrusive. Where others put their ads at the bottom of the app, reducing the app screen real estate and making you touch the ad everytime you want to press play / back / forward, this app inserts its ads in the flow of podcasts. Good design!

Thanks for your work.

Developer Response

Hello Kenijo. We are glad you appreciate Castamatic. I can confirm the app can play episodes in the background and play while silent mode is active. If you continue to experience this problems it's possible you need to reinstall Castamatic or reboot your device. You can contact our support at info at castamatic dot com.

Loved the app but one issue


I had to stop using the app because it downloads episode art and there is no way to prevent this.

Developer Response

Hello Mickeyi04, thank you for your review.
You are right, there is no way at this time to globally disable showing episode specific artwork. If you like you can disable it on a per podcast basis, in every podcast's settings unchecking the last option "Show episode artwork".
We are considering adding options to globally disable both episode artwork and chapter artwork in a future version of the app.
Thanks again for taking the time to review Castamatic!

Amazing app!


Love it. Thanks for all the updates.
