Verdict

The call

The clearest difference is price: Ninja Kitty at Free against Castle Defender Premium's $0.99. Ninja Kitty also leads on ads (none vs shown) and ratings volume (32 vs 1). Castle Defender Premium's advantage is update cadence (every 11 days vs every 2 months) and rating (5.0 vs 4.8). On review sentiment, in-app purchases and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Castle Defender Premium holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Ninja Kitty has 32 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 92% of Ninja Kitty's written reviews are positive against 89% of Castle Defender Premium's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Ninja Kitty ships an update every 2 months, Castle Defender Premium every 11 days. The most recent releases landed on November 1, 2026 and November 3, 2026 respectively.
