ReceptionRating · Positive reviews · Number of ratings

Bounce Defense holds the better App Store score, 4.4 against 3.8. That said, the two scores are not equally well evidenced: Bounce Defense has 1.7K ratings behind it against 12, so its average is the more settled of the two. Written reviews complicate that: 81% of Space War TD's written reviews are positive against 17% of Bounce Defense's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Space War TD ships an update every 3 weeks, Bounce Defense weekly. The most recent releases landed on October 21, 2026 and October 28, 2026 respectively.
