“When I found myself at night and in unfamiliar waters, I had one friend checking the water depth with a pole and another looking for a boat nav app. Luckily we found OceanPulse. We were able to navigate home and I've been a user ever since.”
“Depth and soundings are accurate, works well off the coast. It's the best water nav app I found.”
“OceanPulse is dead simple to use and has free chart data and offline downloads. Finally a modern boat navigation app!”
“I use it every day fishing in the Long Island Sound, usually around Block Island or Newport. Great for tides, winds, weather. I mark all my favorite fishing spots and use the live location sharing when my buddies are out on the water. Great app. 5 stars!”
Tides & currents
Know the water before you get there
Slack, flood, and ebb for more than 3,000 stations across the US — computed on your device, so predictions are always there when the signal isn't.
- 3,000+ stations
- Every NOAA tide and current station, mapped around you.
- The day at a glance
- Rising, falling, slack — scan every nearby station in one list.
- Plan the window
- Full curves for any day — years ahead, no connection needed.
Tracks
Every trip becomes a story
Tap record and drive the boat. OceanPulse quietly logs your course, then turns it into a keeper — stats, a speed graph, and a trip card made for sharing.
- Your logbook, on autopilot
- Every recorded trip lands in your logbook with its course drawn on the chart — named, dated, and easy to find.
- Stats the moment you dock
- Distance, duration, top speed, and a full speed graph — computed automatically the moment you save.
- Made to be shared
- One tap turns any trip into a ready-to-post image — your route, your numbers, your bragging rights.
Offline charts
No signal? No problem.
The best chart plotter is the one that still works past the breakwater. Take your charts with you and navigate like nothing changed.
- Unlimited, and free
- Download as many chart regions as you like. Offline support matters too much to charge for.
- No surprises
- See the download size before you commit, and manage every region from one place.
- Offline-first switch
- Flip one toggle and OceanPulse runs entirely from your device — perfect for slow marina Wi-Fi and none at all.

Questions
Frequently asked questions
What chart coverage is included?
OceanPulse provides chart coverage for the US, the Great Lakes, and US Territories, using official NOAA data at no extra cost. We'll expand more globally in the future, and we promise to keep chart data at as low a cost as possible.
Does it work offline or in low bandwidth conditions?
OceanPulse is designed for low bandwidth conditions. Charts, weather data, and GRIB files are stored on your device until expiry, and only the minimal amount of data is sent over the wire. A data connection is required for the auto routing feature.
What weather models are included?
Weather features are delivered across leading models including ECMWF, GFS, and UKMO, so you can compare predictions side by side. We expect to selectively grow the providers over time.
How often is the weather data refreshed?
All weather predictions are updated on an aggressive rolling basis. As soon as our data providers publish new data, it's available in OceanPulse within 15 minutes or less.
What devices are supported?
OceanPulse is available on iOS and iPadOS, with macOS support on the way. We expect to launch a web version by the end of 2026.
