# Space Frontier vs Interplanetary III

The clearest difference is price: Space Frontier at Free against Interplanetary III's $0.99. Space Frontier also leads on ratings volume (14K vs 23) and review sentiment (47% vs 33%). Interplanetary III's advantage is ads (none vs shown) and update cadence (every 2 weeks vs every 2 months). On in-app purchases and device support there is nothing between them.

Space Frontier is free to download; Interplanetary III costs $0.99 up front. Space Frontier sells 1 one-off in-app purchase and Interplanetary III sells 4 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Interplanetary III holds the better App Store score, 4.5 against 4.3. That said, the two scores are not equally well evidenced: Space Frontier has 14K ratings behind it against 23, so its average is the more settled of the two. Written reviews complicate that: 47% of Space Frontier's written reviews are positive against 33% of Interplanetary III's, so the app with the better star average is not the one people write more warmly about.

Space Frontier ships an update every 2 months, Interplanetary III every 2 weeks. The most recent releases landed on September 14, 2026 and September 16, 2026 respectively.
