# E vs CX

The clearest difference is review sentiment: E at 90% against CX's 36%. E also leads on rating (4.7 vs 3.7) and update cadence (every 2 months vs every 8 months). CX's advantage is price ($19.99 vs $24.95) and chart position (#148 vs unranked). On ads, in-app purchases, monetization model and device support there is nothing between them.

E costs $24.95 and CX $19.99 up front. Neither carries in-app purchases, so what you see is what you pay.

E holds the better App Store score, 4.7 against 3.7. That said, the two scores are not equally well evidenced: E has 57 ratings behind it against 11, so its average is the more settled of the two. Written reviews point the same way: 90% of E's written reviews are positive against 36% of CX's.

E ships an update every 2 months, CX every 8 months. The most recent releases landed on October 12, 2026 and October 13, 2026 respectively.
