Verdict

The call

The clearest difference is price: Superhuman Mail at Free against 15 Minutes's $3.99. Superhuman Mail also leads on ratings volume (3.8K vs 8) and rating (4.6 vs 4.4). 15 Minutes's advantage is review sentiment (67% vs 41%) and chart position (#196 vs unranked). On update cadence, ads, in-app purchases and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Superhuman Mail holds the better App Store score, 4.6 against 4.4. That said, the two scores are not equally well evidenced: Superhuman Mail has 3.8K ratings behind it against 8, so its average is the more settled of the two. Written reviews complicate that: 41% of Superhuman Mail's written reviews are positive against 67% of 15 Minutes's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Superhuman Mail ships an update weekly, 15 Minutes every 2 weeks. The most recent releases landed on November 6, 2026 and November 5, 2026 respectively.
