ReceptionRating · Positive reviews · Number of ratings

Sequoia Mobile holds the better App Store score, 4.9 against 4.3. That said, the two scores are not equally well evidenced: Sequoia Mobile has 22K ratings behind it against 71, so its average is the more settled of the two. Written reviews complicate that: 39% of Sequoia Mobile's written reviews are positive against 74% of Rhombus Key's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Sequoia Mobile ships an update fortnightly, Rhombus Key every 3 weeks. The most recent releases landed on September 23, 2026 and August 23, 2026 respectively.
