# Ninja Kitty vs Castle Defender Premium

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.

Ninja Kitty is free to download; Castle Defender Premium costs $0.99 up front. Ninja Kitty sells 7 one-off in-app purchases and Castle Defender Premium sells 10 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

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.

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.
