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 3.7K 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 8 days. The most recent releases landed on September 29, 2026 and September 18, 2026 respectively.
