Verdict
The clearest difference is rating: Jupiter Attack at 4.5 against Space War GS's 3.3. Jupiter Attack also leads on monetization model (free vs paid) and chart position (#13 vs unranked). Space War GS's advantage is update cadence (every 2 weeks vs every 2 months) and review sentiment (54% vs 40%). On price, ads, in-app purchases and device support there is nothing between them.

Space War GS costs $1.99 and Jupiter Attack $1.99 up front. Neither carries in-app purchases, so what you see is what you pay.
Jupiter Attack holds the better App Store score, 4.5 against 3.3. That said, the two scores are not equally well evidenced: Jupiter Attack has 383 ratings behind it against 52, so its average is the more settled of the two. Written reviews complicate that: 54% of Space War GS's written reviews are positive against 40% of Jupiter Attack's, so the app with the better star average is not the one people write more warmly about.
Space War GS ships an update every 2 weeks, Jupiter Attack every 2 months. The most recent releases landed on October 13, 2026 and October 11, 2026 respectively.
