# Droid Light vs Duet Display

The clearest difference is review sentiment: Droid Light at 90% against Duet Display's 46%. Duet Display's advantage is rating (4.4 vs 3.5) and ratings volume (49K vs 11). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Droid Light sells 1 one-off in-app purchase and Duet Display sells 6 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.

Duet Display holds the better App Store score, 4.4 against 3.5. That said, the two scores are not equally well evidenced: Duet Display has 49K ratings behind it against 11, so its average is the more settled of the two. Written reviews complicate that: 90% of Droid Light's written reviews are positive against 46% of Duet Display's, so the app with the better star average is not the one people write more warmly about.

Droid Light ships an update every 2 months, Duet Display every 3 weeks. The most recent releases landed on September 19, 2026 and September 25, 2026 respectively.
