Verdict

The call

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.

CostPrice · In-app purchases · Ads · Monetization

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.

ReceptionRating · Positive reviews · Number of ratings

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.

UpkeepUpdate frequency

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.
