Sure, here are some basic steps on how to manage the Apple Podcast app:

1. **Finding Podcasts**: Open the Podcast app and tap on the "Browse" tab at the bottom. You can explore featured podcasts, categories, or use the search tab to find a specific one.

2. **Subscribing to a Podcast**: Once you've found a podcast you like, tap on it to open its page. Then tap on the "Subscribe" button. Subscribed podcasts will automatically update with new episodes.

3. **Listening to Podcasts**: Tap on the "Listen Now" tab to see your latest episodes or the "Library" tab to see all your podcasts. You can tap on an episode to start playing it.

4. **Downloading Episodes**: If you want to listen to episodes offline, you can download them. Go to the page of the podcast, find the episode you want, and tap the "+" icon to add it to your library. Then tap the cloud icon to download it.

5. **Managing Subscriptions**: Go to the "Listen Now" or "Library" tab, then tap on "Shows" to see all your subscribed podcasts. You can tap "Edit" to remove any you no longer want.

6. **Setting Playback Preferences**: You can adjust settings like playback speed or set a sleep timer. While an episode is playing, tap the "Playing Next" icon (it looks like a list), then tap the "Playback Speed" or "Sleep Timer" icons.

7. **Syncing Podcasts**: If you want to listen to your podcasts on multiple devices, make sure you're signed in to the same Apple ID on all devices and have "Sync Podcasts" turned on in Settings.

Remember, the Podcast app syncs across all Apple devices, so you can start listening on one device and pick up where you left off on another.
