I'm trying something.

It's a bit of a risk.

By default, URLSession (the iOS HTTP library) saves any cacheable responses to a temp directory within the app's container, and… seems to NEVER delete them.

It didn't affect audio downloads (they're handled differently), but in my testing, this often contained hundreds or thousands of temp files from long-running installs, mostly podcast-artwork images.

In this update, the app manually deletes them all, and switches subsequent requests to in-memory-caching only.

Overcast for iOS 26 is now available!

- Adopted iOS 26's native toolbar buttons everywhere

- Simplified miniplayer to fit iOS 26 style and allow faster access to the playback screen as a giant touch target. (If you want the seek buttons back, switch to Classic under Customize Home Screen!)

- Playback speeds are now offered in 0.1 increments from 0.5–3.0

- Lots of little fixes

Get it now in the App Store! (Works on iOS 18, too.)
