# Superhuman Mail vs Duckbill

The clearest difference is in-app purchases: Duckbill at none against Superhuman Mail's 1. Duckbill also leads on review sentiment (74% vs 41%) and iOS requirement (15.1 vs 26.0). Superhuman Mail's advantage is rating (4.6 vs 4.2) and ratings volume (3.7K vs 69). On price, update cadence, ads and device support there is nothing between them.

Both are free to download. Superhuman Mail sells 1 in-app purchase, starting at $29.99 per month. Duckbill asks for nothing beyond the download.

Superhuman Mail holds the better App Store score, 4.6 against 4.2. That said, the two scores are not equally well evidenced: Superhuman Mail has 3.7K ratings behind it against 69, so its average is the more settled of the two. Written reviews complicate that: 41% of Superhuman Mail's written reviews are positive against 74% of Duckbill's, so the app with the better star average is not the one people write more warmly about.

Both ship on a similar rhythm, roughly weekly. The most recent releases landed on September 25, 2026 and September 14, 2026 respectively.
