Verdict
The clearest difference is rating: CHACOCO at 2.1 against Coupon Navigator's 1.0. CHACOCO also leads on ads (none vs shown) and ratings volume (227 vs 1). Coupon Navigator's advantage is review sentiment (45% vs 12%) and update cadence (every 2 weeks vs every 2 months). On price, in-app purchases and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
CHACOCO holds the better App Store score, 2.1 against 1.0. That said, the two scores are not equally well evidenced: CHACOCO has 227 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 45% of Coupon Navigator's written reviews are positive against 12% of CHACOCO's, so the app with the better star average is not the one people write more warmly about.
Coupon Navigator ships an update every 2 weeks, CHACOCO every 2 months. The most recent releases landed on October 10, 2026 and October 12, 2026 respectively.
