Verdict
The clearest difference is ads: KAI Studio at none against Heartcore's shown. KAI Studio also leads on ratings volume (29 vs 4) and update cadence (every 3 weeks vs every 6 weeks). Heartcore's advantage is device support (3 vs 1) and iOS requirement (14.0 vs 16.0). On price, rating, review sentiment and in-app purchases there is nothing between them.

On the App Store both sit at effectively the same score — 5.0 for Heartcore against 5.0 for KAI Studio.
