# Juno vs Spaceflight Simulator

The clearest difference is price: Spaceflight Simulator at Free against Juno's $6.99. Spaceflight Simulator also leads on rating (4.8 vs 4.4) and ratings volume (98K vs 1.2K). Juno's advantage is in-app purchases (none vs 11). On review sentiment, ads, device support and iOS requirement there is nothing between them.

Spaceflight Simulator is free to download; Juno costs $6.99 up front. Spaceflight Simulator sells 10 one-off in-app purchases. Juno asks for nothing beyond the download.

Spaceflight Simulator holds the better App Store score, 4.8 against 4.4. That said, the two scores are not equally well evidenced: Spaceflight Simulator has 98K ratings behind it against 1.2K, so its average is the more settled of the two. Written reviews point the same way: 78% of Juno's written reviews are positive against 85% of Spaceflight Simulator's.

Juno ships an update monthly, Spaceflight Simulator every 9 days. The most recent releases landed on October 29, 2026 and October 30, 2026 respectively.
