Stop checking three screens before you head out. RipCat brings tide predictions, buoy observations, marine advisories, active hurricane tracks, and customizable Ocean Alerts into one fast, Apple-native app.
A SERIOUSLY USEFUL FREE APP
Start free with one favorite station and one complete custom Ocean Alert recipe. Tide predictions, station search, the map, buoy observations, marine advisories, and hurricane tracking are available without a subscription.
HURRICANE TRACKING
Follow active Atlantic, Eastern Pacific, and Central Pacific systems from official NOAA/NHC/CPHC guidance, including Eastern Pacific storms off Mexico.
• Turn Hurricanes on or off; RipCat remembers your choice
• See observed and forecast tracks, the center-track uncertainty cone, and category-coded fixes
• Compare wind, pressure, movement, and official 34-, 50-, and 64-knot wind fields
• Play or replay the progression, frame the full track, open Details, or use the accessible Storms list
CUSTOMIZABLE OCEAN ALERTS
Tell RipCat what your ocean window looks like. When an on-device check finds a match, RipCat sends a local notification.
• One complete custom alert is free; Pro unlocks up to eight
• Combine multiple conditions and up to three tide or buoy sources
• Choose tide, wave, swell, wind, or water-temperature criteria when the source reports them
• Press and hold for Ocean Aperture: trigger, threshold, direction, height, period, recent trend, wind, and water temperature
• Alert recipes, history, and notifications stay on device. iOS controls background timing
TIDES AT A GLANCE
• Official NOAA CO-OPS predictions for stations around the U.S. coast
• Scrubbable 48-hour curve with exact heights, high and low times, and rising or falling state

DATA SOURCES
NOAA CO-OPS tides, NOAA/NHC/CPHC hurricane guidance, National Weather Service marine forecasts, NDBC observations, and compatible CDIP data. Tide, buoy, and marine station coverage is United States only; NHC hurricane basins can include systems off Mexico. Informational only; not navigation or emergency advice. The cone is not storm size; hazardous effects can occur outside it.

Easy to navigate with accurate information. Displays tide locations that other apps have not been able to provide.
Easy to read and sweet visuals

I found this app really easy to read and look at the tides for the day or the days ahead, also love the visuals and graphics!

One of the latest and last great tide apps of this century, before AI comes for us all, and extinguishes apps altogether. I plan to cling to RipCat’s supreme tidal storytelling until the final mark is upon us.
NIGHT VISION
RipCat 1.7 adds an optional app-wide white-text treatment designed for nighttime use with red Color Tint. Go to Settings > Night Vision > Red-Light Display and choose Automatic, Always On, or Off. Automatic responds when iOS reports Color Filters or Grayscale; because iOS does not reveal which filter or tint is selected, it may also respond to filters used for color-vision or other accessibility needs. Always On gives you deliberate control for red-light use, while Off preserves RipCat’s normal appearance. People use accessibility display settings in different ways. If Red-Light Display affects your experience, please contact RipCat Support, message @ripcatapp on Instagram or via email, dev@ripcat.dev so we can understand and address it. We’re continuing to work with Apple to find the best long-term approach for everyone.
A MAP THAT GETS OUT OF YOUR WAY
Buoys now shift between full condition cards, compact readings, and count-bearing constellations as you zoom. The map keeps targets readable without inventing averaged ocean conditions. Pinch gestures can begin directly over buoy, marine-zone, hurricane, or forecast markers instead of being swallowed by the annotation.
The Small Craft Advisory timeline has a higher-contrast, full-size play control. Marine warnings remain distinguishable by symbols, borders, and luminance when color is reduced.
FULL STORM HISTORY
Hurricane progression now includes the complete official observed track before the current advisory, followed by the forecast. Select historical fixes, compare earlier intensity with current conditions, and replay the entire observed-plus-forecast path. Relative labels such as 2 Days Ago stay paired with the official valid time in Details and VoiceOver context.
MORE RELIABLE MAP ENTRY
This release also fixes the hard termination that could occur when opening Maps on a physical device. Map startup, annotation density, and location ownership are now bounded so the camera and annotation set cannot drive each other into a render loop.
RipCat continues to fetch public NOAA, NWS, NDBC, NHC/CPHC, and compatible CDIP data directly on device. Observations and forecasts are informational only; not navigation or emergency advice.
