# Brex vs Rhombus Key

The clearest difference is rating: Brex at 4.8 against Rhombus Key's 4.3. Brex also leads on ratings volume (8.8K vs 71) and update cadence (weekly vs every 3 weeks). Rhombus Key's advantage is review sentiment (74% vs 46%). On price, ads, in-app purchases and monetization model there is nothing between them.

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

Brex holds the better App Store score, 4.8 against 4.3. That said, the two scores are not equally well evidenced: Brex has 8.8K ratings behind it against 71, so its average is the more settled of the two. Written reviews complicate that: 46% of Brex'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.

Brex ships an update weekly, Rhombus Key every 3 weeks. The most recent releases landed on September 25, 2026 and September 24, 2026 respectively.
