Skindive

Everything to check before you enter the sea at night, in one place. Built for freedivers, spearfishers and seaside foragers. Marine data (tides, high seas advisories, water temperature, coastal CCTV) currently covers Korean waters. ■ Is it a day worth going out? We check for you A 7-day tide table as a traffic light: when low tide comes and how far it drops, waves and wind, and whether big waves days ago stirred up the bottom and ruined visibility. A good tide is wasted if the water is murky, so water clarity comes first: muddy runoff after rain, days of onshore chop, long swell from a distant typhoon, all the things a wave height alone misses. Tap anywhere on the map to open the forecast and tide for that spot. ■ See the sea with your own eyes · Wave, wind and water-temperature layers on a satellite map (scrub the forecast time) · Measured water temperature from National Institute of Fisheries Science stations · Live coastal CCTV: grid-average forecasts can miss the real swell on your beach · Nautical depth charts and a distance ruler · Aquaculture farms and no-entry zones (tap to see why) ■ Never go in alone: find a buddy Find people to go with and plan by direct message. Nearby groups leaving today, region filters, automatic suggestions. Same posts as iPhone users. Your spots stay yours. Listings show only a rough location; the exact entry point goes only to people the poster approved, and only before departure. The app is not hiding it: the server never sends it. Manner reviews from people who actually went together, plus block and report. ■ Exit check-in: set the time you will be out If the time passes with no response, your buddies are notified automatically. Out safely? One tap clears it. Text your emergency contact with one tap, too. ■ Alerts only when they matter · Night foraging: only on mornings when tonight looks good. Choose the time and reference region · High seas advisories: when a new advisory is issued for the sea areas you picked, by the Korea Meteorological Administration's official zone names, so no alerts for offshore waters you would never visit · Used gear: name what you want and get notified of new listings on Korean second-hand marketplaces (Bungaejangter, Danggeun Market, Naver) ■ Dive log Tap Start before you go in and your route and time are recorded; the phone can stay in your bag. Log your catch when out: species, length and weight make it a verified catch. It builds into stats by species, month and tide, plus achievement badges. Overlay the day's record on a photo and share it as one card. ■ Closed seasons and safety The 18 species you cannot take today, closed seasons starting soon, a pre-entry checklist, and one-tap calls to the Korea Coast Guard (122) and emergency services (119). ■ Log the visibility you saw and the forecast gets sharper Some days there is no rain or swell, yet plankton clouds the water and no forecast model catches it. Log what you saw underwater (good, fair, poor, terrible) and the forecast for that area is corrected for a few days. Big waves or heavy rain reset it automatically. Visibility logs stay on this device only, with coordinates blurred to a 1 km grid. ■ Your spots stay yours Saved spots, routes, catch logs and photos live only on this device and are never sent to a server. That is also why catch photos are not uploaded: the spot is in the background. Turn on app lock (fingerprint, face or screen lock) and nobody who picks up your phone can open them. Switching phones? Export and import your spots as a GPX file. --- Safety notice Night and solo entries are dangerous. Never go in alone. The tide, wave and visibility ratings here are for reference only; the final decision to enter the water, and responsibility for it, rest with you. Closed seasons and minimum sizes change yearly and vary by region; the list here is for reference. Check official sources before you go in.
