# 1Chart vs Luna Display

The clearest difference is price: Luna Display at Free against 1Chart's $15.99. Luna Display also leads on rating (4.8 vs 4.3) and ratings volume (4K vs 38). 1Chart's advantage is review sentiment (89% vs 76%). On update cadence, ads, in-app purchases and monetization model there is nothing between them.

Luna Display is free to download; 1Chart costs $15.99 up front. Neither carries in-app purchases, so what you see is what you pay.

Luna Display holds the better App Store score, 4.8 against 4.3. That said, the two scores are not equally well evidenced: Luna Display has 4K ratings behind it against 38, so its average is the more settled of the two. Written reviews complicate that: 89% of 1Chart's written reviews are positive against 76% of Luna Display's, so the app with the better star average is not the one people write more warmly about.

1Chart ships an update every 3 months, Luna Display every 2 months. The most recent releases landed on November 1, 2026 and November 11, 2026 respectively.
