I like this app. Functionally, it works as advertised and performs consistantly; the integration of space (geography), time, and data (tidal flow) is presented clearly and in a efficent manner; the satellite integration works smoothly. I do not know their algorythm for calculating "any place tide levels", but it seems consistant with key point data from public tidal tables.Lastly, they have way above average application documentation and support.. As a geographer,I think its simple and elegant. As a fisherman, its a dandy tool. Nice job!! ***I highly RECOMMEND this app***
