Verdict

The call

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.

ReceptionRating · Positive reviews · Number of ratings

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.

UpkeepUpdate frequency

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.
