This is becoming something of a weekly update - the OneCast UWP podcatcher is coming on leaps and bounds and, thanks to the developer, we actually have a detailed changelog. Auto-downloads are back (hooray!), along with ways of filtering, marking and (yes) deleting old episodes. OneCast's Unique Selling Point is the ultra-simple UI and this is maintained on the whole - this could indeed be the 'One' podcatcher you need?
Fixed high data usage behavior on metered connections
Fixed large opml import causing app crash
Fixed issue with url detection in searchbox
Fixed intermittant crash during playback
Fixed failure to load some cover art
Fixed cover art sizing issue
As you can see, the developer has been busy again! Another impressive release, here it is in action:
The various screen elements are worth tapping on, as always; (right) tapping on the developer's name pops up new options, including a handy 'What's New' list, as featured above.
New for this version is a background bar underneath each episode's title and information, showing how much of it has been played so far. Nicely done, the same applies to the 'now playing' bar at the bottom too; (right) you can also now 'select all' within any of the views and delete old episodes - handy if you need to do any manual clearing up of shows that you never got round to listening to.
Also new for this version is a new long-press menu item, 'Auto download' - this marks the podcast for a background process to grab over Wi-fi.
