Everything you plan a session around.
Tide, solunar, and alerts in one clean view, with the offline reliability the coast demands.
Open to the answer: tide now, next turn, and the bite.
Tide curve and times, on device
Open the app to today's tide curve, the next high or low, and the height at any moment. Touch and hold the curve to read the height at any time. Computed from NOAA harmonic data on your iPhone, so it works with no signal.
Solunar, sun, and moon
Major and minor feeding windows with a daily bite rating, plus sunrise and sunset, moonrise and moonset, moon phase, twilight, and the golden hour.
Best fishing days
A two-week outlook that ranks each day by its tidal range and the solunar bite, so you can pick the best day to be on the water.
Air pressure trend
Reads your iPhone's barometer for local air pressure and its trend, a signal anglers plan around. Fully on device, no network.
Smart alerts
A heads up before low tide, slack water, or an ideal bite window, plus custom tide-height alarms for a boat-launch minimum or a causeway maximum. Scheduled on your device.
Currents and slack windows
Flood, ebb, and the slack water the app is named for. See when the water goes quiet at your station, the window that anglers, divers, and paddlers plan around.
Live tide on your lock screen
Track the next turn as a live countdown on your lock screen and in the Dynamic Island. As a turn gets close, the app offers to track it for you.
A log that learns your water
Every session you log stamps the tide and the bite at that moment, with an optional photo. After a few sessions, your pattern appears: how often you do well on a rising tide, or during a strong bite. Private, on your device.
Widgets, StandBy, and Apple Watch
The current tide and bite on your home screen, lock screen, nightstand StandBy, and wrist. Flip between saved spots right on the widget, and the Smart Stack surfaces it as a turn approaches.
Siri and iPhone search
Ask Siri for the tide, the next turn, or today's bite, or log a session by voice. Every US station and every saved spot shows up in iPhone search.
Private and offline
Your spots and settings live on your device and sync through your own iCloud. No account, no ads, no tracking.
In your language, your units
English, Spanish, and Brazilian Portuguese, with feet or meters chosen per spot.
