Turn the phone to look around; tilt the lid back to look higher. • Open it like a book — a star atlas: the map on one page, the story of what you're looking at on the other. • Lay it flat — the whole sky on one star wheel. • Tonight, Explore, Passes and Tools use both halves of the screen.

Switch the drawings off anytime. • Eclipse & Sky Event Calendar — Solar and lunar eclipses, meteor showers, planet conjunctions and oppositions, full moons, equinoxes and solstices, all calculated for your exact location with the best time to look. Get an alert before each one. • Milky Way & Deep-Sky Photos — A real Milky Way across your sky, plus telescope photos of 30 galaxies, nebulae and star clusters — Andromeda, the Orion Nebula, the Pleiades — shown exactly where they are. • Home & Lock Screen Widgets — Tonight's Moon phase and the next sky event, at a glance. • More Accurate AR — The sky stays lined up when you tilt your phone, and you can align it to the Sun or Moon in seconds.

Verdict
The clearest difference is review sentiment: Sky Map at 100% against Sky Map's 0%. Sky Map also leads on rating (4.5 vs 1.0) and update cadence (fortnightly vs every 5 weeks). On price, 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
Both are free to download. Sky Map sells 3 in-app purchases, starting at $7.99 per month and Sky Map sells 2 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.
Sky Map holds the better App Store score, 4.5 against 1.0. That said, the two scores are not equally well evidenced: Sky Map has 6 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 0% of Sky Map's written reviews are positive against 100% of Sky Map's.
Sky Map ships an update every 5 weeks, Sky Map fortnightly. The most recent releases landed on November 9, 2026 and November 5, 2026 respectively.
