On-device NOAA harmonic prediction. Unlimited future dates, every station, and it works with zero signal — because zero signal is exactly where you'll be standing.
The tide comes in whether or not you have a bar of signal. Ebb runs the whole prediction on-device, so the app that plans your trip is the app that works when you get there.
Tide predictions computed on your phone from NOAA harmonic data — no signal required, unlimited future dates.
Solunar majors & minors overlaid on the tide curve, starred when they stack with dawn, dusk, or a tide swing.
Next high/low on your home screen; a countdown through the bite window on your lock screen.
"Major window in 45 min" — the nudge that lands before you'd have thought to check.
Every one of these apps paywalls the same bundle — widgets, unlimited dates, alerts, offline. The features are table stakes. The only line that really changes is the price.

No trash talk — these are good apps. Ebb just doesn't think a tide chart and a fishing calendar should bill you every April.
The moon is free. The tide is free.Why Ebb costs $9.99, once
Your tide app shouldn't be $30 a year.
