# Spaceflight Simulator vs Juno

The clearest difference is rating: Spaceflight Simulator at 4.8 against Juno's 3.8. Spaceflight Simulator also leads on ads (none vs shown) and ratings volume (98K vs 325). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Spaceflight Simulator sells 10 one-off in-app purchases and Juno sells 4 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Spaceflight Simulator holds the better App Store score, 4.8 against 3.8. That said, the two scores are not equally well evidenced: Spaceflight Simulator has 98K ratings behind it against 325, so its average is the more settled of the two. Written reviews point the same way: 85% of Spaceflight Simulator's written reviews are positive against 62% of Juno's.

Spaceflight Simulator ships an update every 9 days, Juno monthly. The most recent releases landed on October 29, 2026 and October 27, 2026 respectively.
