NASA's Earth Now is an application that visualizes recent global climate data from Earth Science satellites, including surface air temperature, carbon dioxide, carbon monoxide, ozone, and water vapor as well as gravity and sea level variations. Data sets are visually described using "false color" maps. Color-coded legends are provided to indicate relative strength or weakness of an environmental condition. The resulting 3D model of the Earth may be rotated by a single finger stroke, and may also be zoomed in or out by pinching 2 fingers. It was developed by the Earth Science Communications and Visualization Technology Applications and Development Teams at NASA's Jet Propulsion Laboratory, with support from NASA Headquarters.

Verdict
The clearest difference is price: Earth at Free against NEOScope's $0.99. Earth also leads on ratings volume (42 vs 1) and device support (3 vs 1). NEOScope's advantage is rating (5.0 vs 4.6) and review sentiment (100% vs 74%). On update cadence, ads and in-app purchases 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
Earth is free to download; NEOScope costs $0.99 up front. Neither carries in-app purchases, so what you see is what you pay.
NEOScope holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Earth has 42 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 74% of Earth's written reviews are positive against 100% of NEOScope's.
Earth ships an update every 4 months, NEOScope every 7 months. The most recent releases landed on October 20, 2026 and October 24, 2026 respectively.
