Know what you'll see before you dive — the first app to forecast both marine life abundance and underwater visibility, at dive sites worldwide. Updated daily. Pick the right site, the right day, and the right season before you ever get wet. WHY DIVESIGHT Weather apps help tell you if you can dive. DiveSight also tells you how good it's likely to be — how much marine life you're likely to encounter and how far you'll see, days in advance, anywhere in the world. It's the difference between hoping and making decisions based on the best ocean intelligence available. THE FORECASTS - Marine Life Index (0–100) of abundance for every site, updated daily — see which days will be better than usual, up to a week ahead. - Underwater visibility — including the tens of thousands of sites no crowdsourced app has reports for. DiveSight predicts visibility worldwide from satellite data and fisheries oceanography. Plan your dive with confidence. – 10 years of monthly climatology per site: water temperature, visibility, currents, weather, wind, and more — so you can pick the actual best month to go, year over year. – Depth-resolved conditions: temperatures at the surface, 10m/30ft, and 30m/90ft, plus currents, waves, tides, sun, and moon.

Zoom into Raja Ampat, Cozumel, the Red Sea, Komodo, the Maldives, the Galápagos, or the hidden sites between them. – By creature — search 6,000+ marine species and see exactly where and when you can dive with them: hammerheads, mantas, mola mola, whale sharks, mandarinfish, thresher sharks, nudibranchs, and thousands more. Every species linked to the sites, seasons, and regions where it appears. – Around you — tap once to see every dive site within range, sorted by today's conditions, marine life, or distance. Perfect for layovers, road trips, and your local shore dive. – By season — a calendar of bucket-list events with predicted timing windows: the sardine run, manta cleaning stations, hammerhead schools, whale shark aggregations, mobula ray gatherings, and spawning events.

Verdict
The clearest difference is ads: DiveSight at none against Surf Captain's shown. DiveSight also leads on review sentiment (100% vs 80%). Surf Captain's advantage is ratings volume (1.3K vs 31) and chart position (#169 vs unranked). On price, rating, update cadence and in-app purchases there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Surf Captain sells 3 in-app purchases, starting at $9.99 per year and DiveSight sells 3 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.
On the App Store both sit at effectively the same score — 4.9 for Surf Captain against 5.0 for DiveSight. That said, the two scores are not equally well evidenced: Surf Captain has 1.3K ratings behind it against 31, so its average is the more settled of the two. Written reviews are what separate them: 80% of Surf Captain's written reviews are positive against 100% of DiveSight's.
Both ship on a similar rhythm, roughly weekly. The most recent releases landed on November 11, 2026 and November 5, 2026 respectively.
