# Mainfreight vs Rhombus Key

The clearest difference is rating: Mainfreight at 5.0 against Rhombus Key's 4.3. Rhombus Key's advantage is update cadence (every 3 weeks vs every 3 months) and review sentiment (74% vs 54%). 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.

Mainfreight holds the better App Store score, 5.0 against 4.3. That said, the two scores are not equally well evidenced: Rhombus Key has 71 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 54% of Mainfreight'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.

Mainfreight ships an update every 3 months, Rhombus Key every 3 weeks. The most recent releases landed on October 7, 2026 and October 20, 2026 respectively.
