# LetsView vs Duet Air

The clearest difference is rating: Duet Air at 4.3 against LetsView's 2.6. Duet Air also leads on update cadence (every 3 weeks vs every 6 months) and ratings volume (1.9K vs 25). LetsView's advantage is in-app purchases (none vs 2) and ads (none vs shown). On price 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. LetsView asks for nothing beyond the download.

Duet Air holds the better App Store score, 4.3 against 2.6. That said, the two scores are not equally well evidenced: Duet Air has 1.9K ratings behind it against 25, so its average is the more settled of the two. Written reviews complicate that: 33% of LetsView's written reviews are positive against 24% of Duet Air's, so the app with the better star average is not the one people write more warmly about.

LetsView ships an update every 6 months, Duet Air every 3 weeks. The most recent releases landed on October 24, 2026 and October 27, 2026 respectively.
