About
Apps built for life on the water.
Mariner App LLC builds practical, privacy-respecting mobile software for boaters, crews and anyone who spends time beyond reliable coverage.
Our products
Two apps, two independent products, one small team behind both.
How we work
Privacy is the default
No advertising networks, no data resale, no behavioural profiles. Where end-to-end encryption is possible, it is on by default and we hold no keys.
Honest about limits
Our apps tell you what they cannot do. Mariner Mesh is not a distress system. Vessel IQ estimates are not a survey. We would rather be trusted than oversold.
Built by people who use them
Every feature starts with a real problem on a real boat or trail — not a roadmap slide. If something is not working, we want to hear about it.
