# Duet Air vs WhenWas

The clearest difference is review sentiment: WhenWas at 100% against Duet Air's 24%. WhenWas also leads on rating (5.0 vs 4.3) and monetization model (freemium vs subscription). Duet Air's advantage is ratings volume (1.9K vs 4) and iOS requirement (12.0 vs 18.0). On price, update cadence, in-app purchases 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 and WhenWas sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

WhenWas holds the better App Store score, 5.0 against 4.3. That said, the two scores are not equally well evidenced: Duet Air has 1.9K ratings behind it against 4, so its average is the more settled of the two. Written reviews point the same way: 24% of Duet Air's written reviews are positive against 100% of WhenWas's.

Duet Air ships an update every 3 weeks, WhenWas every 2 weeks. The most recent releases landed on September 22, 2026 and September 8, 2026 respectively.
