# CJ ONE vs Emergency Ready App

The clearest difference is rating: CJ ONE at 3.5 against Emergency Ready App's 2.5. CJ ONE also leads on ratings volume (37 vs 2). Emergency Ready App's advantage is ads (none vs shown) and review sentiment (100% vs 71%). On price, in-app purchases, device support and iOS requirement there is nothing between them.

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

CJ ONE holds the better App Store score, 3.5 against 2.5. That said, the two scores are not equally well evidenced: CJ ONE has 37 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 71% of CJ ONE's written reviews are positive against 100% of Emergency Ready App's, so the app with the better star average is not the one people write more warmly about.

CJ ONE ships an update monthly, Emergency Ready App every 2 weeks. The most recent releases landed on October 17, 2026 and October 16, 2026 respectively.
