# CX vs TwoTenDegrees

The clearest difference is price: TwoTenDegrees at Free against CX's $19.99. TwoTenDegrees also leads on rating (5.0 vs 3.7) and update cadence (every 9 days vs every 8 months). CX's advantage is review sentiment (36% vs 0%) and ratings volume (11 vs 1). On ads, in-app purchases, device support and iOS requirement there is nothing between them.

TwoTenDegrees is free to download; CX costs $19.99 up front. Neither carries in-app purchases, so what you see is what you pay.

TwoTenDegrees holds the better App Store score, 5.0 against 3.7. That said, the two scores are not equally well evidenced: CX has 11 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 36% of CX's written reviews are positive against 0% of TwoTenDegrees's, so the app with the better star average is not the one people write more warmly about.

CX ships an update every 8 months, TwoTenDegrees every 9 days. The most recent releases landed on September 25, 2026 and September 9, 2026 respectively.
