Verdict

The call

The clearest difference is in-app purchases: Harbour Guide at none against ARK's 10. Harbour Guide also leads on review sentiment (33% vs 0%). ARK's advantage is update cadence (every 2 weeks vs every 6 months). On price, ads, monetization model and device support there is nothing between them.
