Verdict
The clearest difference is rating: HK Express at 4.4 against KKFly's 3.7. HK Express also leads on in-app purchases (none vs 4) and ads (none vs shown). KKFly's advantage is review sentiment (26% vs 18%) and iOS requirement (11.0 vs 15.6). On price, update cadence 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. KKFly sells 4 in-app purchases, starting at $9.99 per month. HK Express asks for nothing beyond the download.
HK Express holds the better App Store score, 4.4 against 3.7. That said, the two scores are not equally well evidenced: HK Express has 1.8K ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 18% of HK Express's written reviews are positive against 26% of KKFly's, so the app with the better star average is not the one people write more warmly about.
HK Express ships an update every 3 weeks, KKFly fortnightly. The most recent releases landed on October 17, 2026 and October 14, 2026 respectively.
