# Duet Air vs Display Share

The clearest difference is rating: Display Share at 5.0 against Duet Air's 4.3. Display Share also leads on in-app purchases (none vs 2) and ads (none vs shown). Duet Air's advantage is ratings volume (1.9K vs 2) and iOS requirement (12.0 vs 14.0). On price, update cadence and device support there is nothing between them.

Both are free to download. Duet Air sells 2 in-app purchases, starting at $49.99 per year. Display Share asks for nothing beyond the download.

Display Share holds the better App Store score, 5.0 against 4.3. That said, the two scores are not equally well evidenced: Duet Air has 1.9K ratings behind it against 2, so its average is the more settled of the two.

Duet Air ships an update every 3 weeks, Display Share every 5 weeks. Both last shipped on October 27, 2026.
