What’s included

Everything the app does, with nothing behind a purchase.

Tide predictions for all US stations — primary stations and subordinate stations alike.
Any station, any date — look ahead to a trip or back at a day you fished.
Tide graph — the day’s curve with highs and lows marked.
Tidal current predictions — current graphs mark slack, max flood and max ebb with their times, and a Now line shows where you are in the cycle.
Sunrise, sunset, moonrise and moonset — alongside the tide for the same day.
Moon phase — the current phase and moon age, the phases coming up, and a month-at-a-glance calendar.
Reference and subordinate stations labelled — so you know which kind you’re reading.
Favorite stations — the water you use most, first.
Distance from your location — so the nearest station is obvious.
Station map — find a station visually instead of by name.
On-device predictions — the maths runs on your phone, so tides work without a signal.
