“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.”

“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!”

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?

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.
