Verdict

The call

The clearest difference is in-app purchases: Multicast at none against CastDuo's 15. Multicast also leads on rating (4.5 vs 4.0) and device support (3 vs 1). CastDuo's advantage is update cadence (every 8 days vs every 4 months) and ratings volume (102 vs 2). On price and ads there is nothing between them.

Both are free to download. CastDuo sells 15 in-app purchases, starting at $2.49 per 7 days. Multicast asks for nothing beyond the download.

ReceptionRating · Positive reviews · Number of ratings

Multicast holds the better App Store score, 4.5 against 4.0. That said, the two scores are not equally well evidenced: CastDuo has 102 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 20% of CastDuo's written reviews are positive against 0% of Multicast's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

CastDuo ships an update every 8 days, Multicast every 4 months. The most recent releases landed on October 27, 2026 and October 5, 2026 respectively.
