Verdict

The call

The clearest difference is price: NASA at Free against SkyView®'s $2.99. NASA also leads on update cadence (every 2 weeks vs every 4 months) and rating (4.8 vs 4.6). SkyView®'s advantage is chart position (#2 vs unranked). On review sentiment, ads, in-app purchases and monetization model there is nothing between them.

Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS

CostPrice · In-app purchases · Ads · Monetization

NASA is free to download; SkyView® costs $2.99 up front. Neither carries in-app purchases, so what you see is what you pay.

ReceptionRating · Positive reviews · Number of ratings

NASA holds the better App Store score, 4.8 against 4.6. That said, the two scores are not equally well evidenced: NASA has 64K ratings behind it against 7.7K, so its average is the more settled of the two. Written reviews complicate that: 70% of NASA's written reviews are positive against 77% of SkyView®'s, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

NASA ships an update every 2 weeks, SkyView® every 4 months. Both last shipped on October 2, 2026.
