Verdict

The call

The clearest difference is price: CrewView at Free against TideMeasure's $19.99. CrewView also leads on iOS requirement (12.0 vs 17.0). TideMeasure's advantage is update cadence (every 2 months vs every 4 months) and chart position (#197 vs unranked). On review sentiment, ads, in-app purchases and device support there is nothing between them.
