# Argus vs Duffy

The clearest difference is ads: Duffy at none against Argus's shown. Argus's advantage is update cadence (monthly vs every 5 months) and ratings volume (36K vs 757). On price, review sentiment, in-app purchases and monetization model there is nothing between them.

Both are free to download. Argus sells 10 in-app purchases, starting at $4.99 per month and Duffy sells 4 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Argus holds the better App Store score, 4.9 against 4.7. That said, the two scores are not equally well evidenced: Argus has 36K ratings behind it against 757, so its average is the more settled of the two. Written reviews complicate that: 82% of Argus's written reviews are positive against 84% of Duffy's, so the app with the better star average is not the one people write more warmly about.

Argus ships an update monthly, Duffy every 5 months. The most recent releases landed on September 24, 2026 and September 23, 2026 respectively.
