# Star Chart vs Star Map Tracker

The clearest difference is review sentiment: Star Chart at 85% against Star Map Tracker's 29%. Star Chart also leads on update cadence (fortnightly vs every 5 months) and ratings volume (25K vs 1). Star Map Tracker's advantage is rating (5.0 vs 4.6). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Star Chart sells 7 one-off in-app purchases and Star Map Tracker sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Star Map Tracker holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Star Chart has 25K ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 85% of Star Chart's written reviews are positive against 29% of Star Map Tracker's, so the app with the better star average is not the one people write more warmly about.

Star Chart ships an update fortnightly, Star Map Tracker every 5 months. The most recent releases landed on October 29, 2026 and October 24, 2026 respectively.
