Verdict

The call

The clearest difference is review sentiment: Shore TideChart at 92% against PredictCurrent's 57%. Shore TideChart also leads on update cadence (every 9 days vs monthly) and rating (4.7 vs 4.5). PredictCurrent's advantage is ads (none vs shown) and ratings volume (255 vs 13). On price, in-app purchases, monetization model and device support there is nothing between them.
