Verdict

The call

The clearest difference is rating: HK_Sky Line at 5.0 against ARFlowArts's 3.8. HK_Sky Line also leads on in-app purchases (none vs 10) and iOS requirement (5.1.1 vs 16.4). ARFlowArts's advantage is update cadence (every 3 days vs every 3 months) and ratings volume (50 vs 1). On price, ads and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

HK_Sky Line holds the better App Store score, 5.0 against 3.8. That said, the two scores are not equally well evidenced: ARFlowArts has 50 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 20% of HK_Sky Line's written reviews are positive against 38% of ARFlowArts's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

HK_Sky Line ships an update every 3 months, ARFlowArts every 3 days. The most recent releases landed on November 2, 2026 and November 11, 2026 respectively.
