Very useful app but...
I use it on a constant basis as a live reference but always combined with proper written tidal documents.
Great tool but I noticed some slight difference in water level & important time differences between actual CCG ( Canadian) tides publications and prediction in TP that ranges from a few minutes to +/- 35 minutes in some locations for the past 3 years.
Still using it as a quick reference once I know the daily variations.
