Store description excerpt
Tide tables for 3,000+ US NOAA stations, moon phases, solunar fishing-activity forecasts, sun rise/set — bundled completely offline, beautiful at the beach or 50 miles off the coast with no signal. A tap on any day shows the full tidal curve, the lunar disc, the sun arc, the wind / swell / temperature for that hour. A widget on your home screen shows tonight's tide, tomorrow's first light, and Friday's moon phase at a glance. No ads. No "Pro fishing AI" upsell. No location uploaded to a server. The data is the data — public NOAA tide stations and a 1,200-year-tested astronomy algorithm.
