DiveSight: Scuba Forecasts - Visibility and Marine Life Forecasts for Divers

Hi Product Hunt community! I'm the founder of DiveSight. I'm a lifelong diver with 33 years of experience and a PhD statistician, and this started as a fish abundance forecasting tool for one of my academic research projects. It became the tool I always wanted for dive planning, built to answer a question no existing tool really could: not what a dive site's conditions were, but what they're likely to be when I'm in the water. Planning a dive trip used to mean stitching together a list of potential dive sites, a separate source for sea conditions, another for tides, another for weather, and scattered forum threads with diver reports on conditions and marine life. None of it connected, and almost all of it was retrospective. DiveSight does three things: Forecasts conditions. It predicts underwater visibility, marine life abundance, and diver-relevant oceanography at dive sites worldwide, combining near-real-time satellite data, established ocean models, and our own machine learning. It's a forecast, so treat it like one, but it's a real signal for deciding whether a site is worth the trip that week. Works anywhere on Earth. The forecast isn't limited to a fixed list or limited diver reports. You can pull up one of our 28,000+ cataloged sites or drop a pin on any coordinates, including a custom spot no one has logged before, and get an outlook for it. To my knowledge, a worldwide, on-demand visibility and marine life forecast hasn't existed before. Maps marine life to places. Over 6,000 species mapped to those sites, so you can plan around what you actually want to see, plus depth, hazards, and a personal dive log. A few other things it does: - A seasonal calendar of bucket-list marine events, so you can time a trip around things like aggregations, migrations, and spawning. - Marine life logging that connects to global citizen-science records, so your sightings can contribute meaningfully to the global biodiversity record. - Recent sightings for the full database of sites, pulled from diver logs and public databases. It's free on iOS (a one-week Pro trial is free, no card required). Two things I'd love feedback on: if you dive and have any coming up, navigate to the site in the app and tell me how the forecast holds up. That's the most useful signal I can get. Even if you don't dive, a couple of things are worth a look on their own: the marine life catalog of 6,000+ species you can search and explore, and how the app turns complex ocean data into something readable at a glance. I'd love feedback on whether that simplicity comes through. Happy to answer anything in the comments.
