Verdict

The call

The clearest difference is in-app purchases: Pocket Galaxy at none against Spaceflight Simulator's 11. Pocket Galaxy also leads on iOS requirement (11.0 vs 15.0). Spaceflight Simulator's advantage is ads (none vs shown) and update cadence (every 9 days vs every 6 months). On price, review sentiment, monetization model and device support there is nothing between them.

Both are free to download. Spaceflight Simulator sells 10 one-off in-app purchases. Pocket Galaxy asks for nothing beyond the download.

ReceptionRating · Positive reviews · Number of ratings

Spaceflight Simulator holds the better App Store score, 4.8 against 4.6. Both are backed by a comparable volume of ratings — 25K and 97K respectively. Written reviews complicate that: 92% of Pocket Galaxy's written reviews are positive against 86% of Spaceflight Simulator's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Pocket Galaxy ships an update every 6 months, Spaceflight Simulator every 9 days. Both last shipped on September 25, 2026.
