# Duet Display vs ASUS GlideX

The clearest difference is review sentiment: ASUS GlideX at 92% against Duet Display's 46%. ASUS GlideX also leads on ads (none vs shown) and rating (4.8 vs 4.4). Duet Display's advantage is ratings volume (49K vs 2.3K) and iOS requirement (12.0 vs 14.0). On price, update cadence, in-app purchases and device support there is nothing between them.

Both are free to download. Duet Display sells 6 in-app purchases, starting at $3.99 per month and ASUS GlideX sells 3 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.

ASUS GlideX holds the better App Store score, 4.8 against 4.4. That said, the two scores are not equally well evidenced: Duet Display has 49K ratings behind it against 2.3K, so its average is the more settled of the two. Written reviews point the same way: 46% of Duet Display's written reviews are positive against 92% of ASUS GlideX's.

Duet Display ships an update every 3 weeks, ASUS GlideX every 6 weeks. Both last shipped on September 24, 2026.
