# Starry Map vs 星空ナビ

The clearest difference is ads: 星空ナビ at none against Starry Map's shown. 星空ナビ also leads on rating (4.7 vs 4.5). Starry Map's advantage is review sentiment (62% vs 29%) and ratings volume (246 vs 3). On price, in-app purchases, device support and iOS requirement there is nothing between them.

Both are free to download. Starry Map sells 5 in-app purchases, starting at $0.99 per month and 星空ナビ sells 2 in-app purchases, starting at $1.49 per month. Whichever you choose, the download price is not the number that matters.

星空ナビ holds the better App Store score, 4.7 against 4.5. That said, the two scores are not equally well evidenced: Starry Map has 246 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 62% of Starry Map's written reviews are positive against 29% of 星空ナビ's, so the app with the better star average is not the one people write more warmly about.

Starry Map ships an update every 2 weeks, 星空ナビ every 6 weeks. The most recent releases landed on October 17, 2026 and October 2, 2026 respectively.
