Verdict

The call

The clearest difference is review sentiment: Continuity Digital Signage at 100% against Duet Display's 46%. Continuity Digital Signage also leads on ads (none vs shown). Duet Display's advantage is rating (4.4 vs 3.5) and ratings volume (49K vs 2). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. Duet Display sells 6 in-app purchases, starting at $3.99 per month and Continuity Digital Signage sells 3 in-app purchases, starting at $8.99 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 2, so its average is the more settled of the two. Written reviews complicate that: 46% of Duet Display's written reviews are positive against 100% of Continuity Digital Signage's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Duet Display ships an update every 3 weeks, Continuity Digital Signage every 6 weeks. The most recent releases landed on September 26, 2026 and June 7, 2026 respectively.
