QUESTIONS: Wondering if:
1. App has "rewind" by ## seconds
2. If a Mac subscription will sync with iOS subscription.
3. Can it play podcasts which ONLY exist locally (ie on my computer)
Downcast for iDevices has never worked 100% for syncing. If syncing is your goal, good luck, or at least better luck than mine! Apart from syncing, Downcast has been reliable.
