# Duet Display vs WO Mic

The clearest difference is rating: Duet Display at 4.4 against WO Mic's 2.3. Duet Display also leads on update cadence (every 3 weeks vs every 7 months) and ratings volume (49K vs 224). WO Mic's advantage is ads (none vs shown). On price, review sentiment, 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 WO Mic sells 2 in-app purchases, starting at $0.99 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 2.3. That said, the two scores are not equally well evidenced: Duet Display has 49K ratings behind it against 224, so its average is the more settled of the two. Written reviews point the same way: 45% of Duet Display's written reviews are positive against 38% of WO Mic's.

Duet Display ships an update every 3 weeks, WO Mic every 7 months. The most recent releases landed on October 21, 2026 and October 19, 2026 respectively.
