Verdict

The call

The clearest difference is price: GalacticAR at Free against Star Walk 2 Pro's $2.99. GalacticAR also leads on review sentiment (88% vs 72%) and device support (6 vs 3). Star Walk 2 Pro's advantage is ratings volume (67K vs 116) and rating (4.7 vs 4.5). On update cadence, ads, in-app purchases and monetization model there is nothing between them.

GalacticAR is free to download; Star Walk 2 Pro costs $2.99 up front. Star Walk 2 Pro sells 8 one-off in-app purchases and GalacticAR sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

Star Walk 2 Pro holds the better App Store score, 4.7 against 4.5. That said, the two scores are not equally well evidenced: Star Walk 2 Pro has 67K ratings behind it against 116, so its average is the more settled of the two. Written reviews complicate that: 72% of Star Walk 2 Pro's written reviews are positive against 88% of GalacticAR's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Star Walk 2 Pro ships an update every 2 months, GalacticAR every 4 weeks. The most recent releases landed on September 24, 2026 and September 19, 2026 respectively.
