Verdict

The call

The clearest difference is update cadence: Kontainer at every 10 days against Harbour's every 6 weeks. Kontainer also leads on review sentiment (100% vs 88%) and iOS requirement (15.0 vs 18.0). Harbour's advantage is price ($2.99 vs $6.99) and chart position (#55 vs unranked). On ads, in-app purchases, monetization model and device support there is nothing between them.
