# 쿠펀치 vs e

The clearest difference is ratings volume: e at 37 against 쿠펀치's 2. e also leads on iOS requirement (13.0 vs 15.0). 쿠펀치's advantage is update cadence (every 2 weeks vs monthly). On price, rating, review sentiment and ads there is nothing between them.

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

On the App Store both sit at effectively the same score — 1.0 for 쿠펀치 against 1.1 for e. That said, the two scores are not equally well evidenced: e has 37 ratings behind it against 2, so its average is the more settled of the two. Written reviews are what separate them: 5% of 쿠펀치's written reviews are positive against 11% of e's.

쿠펀치 ships an update every 2 weeks, e monthly. Both last shipped on October 15, 2026.
