Verdict
The clearest difference is rating: HUA at 5.0 against Harena's 3.0. HUA also leads on ads (none vs shown) and monetization model (free vs ad-supported). On price, in-app purchases, device support and iOS requirement 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.
HUA holds the better App Store score, 5.0 against 3.0. That said, the two scores are not equally well evidenced: HUA has 6 ratings behind it against 1, so its average is the more settled of the two.
