# iDisplay vs Luna Display

The clearest difference is review sentiment: Luna Display at 76% against iDisplay's 20%. Luna Display also leads on rating (4.8 vs 1.9) and ratings volume (4K vs 105). iDisplay's advantage is device support (3 vs 1) and iOS requirement (8.0 vs 13). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Luna Display holds the better App Store score, 4.8 against 1.9. That said, the two scores are not equally well evidenced: Luna Display has 4K ratings behind it against 105, so its average is the more settled of the two. Written reviews point the same way: 20% of iDisplay's written reviews are positive against 76% of Luna Display's.

iDisplay ships an update every 6 weeks, Luna Display every 2 months. Both last shipped on October 24, 2026.
