Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
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.
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.
