No ads, no sign-up. Offline, you still see the last forecast loaded for cities and points you've already opened. See whether it's worth getting in the water today. Spearo (spearo.app) covers spearfishing and freediving in 2,600+ coastal cities across 60+ countries. The forecast comes from our own ML model, which weighs dozens of factors, including swell, wind, tides, rain and water temperature. Most of us check three or four apps before a dive: wind in one, swell in another, tides in a third. Then we drive to the beach and find murky water anyway. Spearo checks swell height and period, wind, visibility and tides to give you a daily verdict before you leave home. Green: there's a window to dive today, and you can see which hours. Yellow: borderline. There's less time to dive and less room for error. Red: there's a good reason to wait, and Spearo shows the next good day. Water visibility forecast Spearo predicts visibility on your coast in meters. Our own ML model works it out from dozens of factors, including swell, wind, tides, rain and water temperature, so a stirred-up sea won't surprise you at the entry point. Murky water doesn't always mean there are no fish, and whether you go in is up to you. Seafloor map & no-take zones A satellite map of your coast with depth contours, plus seafloor detail where we have it, so you can read the bottom before you get in. Marine reserves and no-take zones in 25 countries are marked on the map. They're shown for information only, so always check the current local rules. Tides, swell & wind An hourly marine forecast: wave height, swell period, wind speed and gusts, water temperature, visibility and an hourly tide chart. It runs up to 7 days ahead. The first days are free and the full week comes with Pro. Spearfishing spots 8,000+ mapped spots along the coast (reefs, wrecks and ledges), each with its own forecast. Some spot forecasts require Pro or Ultra. My points Save your own points anywhere on the map: 3 free, 5 with Pro, 10 with Ultra. A reef, a drop-off, a mark you keep to yourself. Spearo builds a full 7-day forecast for those exact coordinates. Dive log After a dive, note what the water was really like: first how well the forecast matched, then visibility in meters, waves and fish activity. Over time you'll see how your spot behaves. Home Screen and Lock Screen widgets Put the week strip and the verdict on your Home Screen, and see today's answer on your Lock Screen. Home Screen widgets can follow your city or any saved point. Alerts A short morning digest for your city or your points, and a heads-up when today's verdict is green at a point you follow. Alerts for one location are free; follow more with Pro. You can manage the morning digest and dive alerts in Settings. Fish & safety Local fish species, minimum sizes where available, and official sea warnings where they're issued. Who it's for Spearfishing · freediving · apnea · snorkeling · open-water swimming · kayak & SUP · rock and shore fishing. For anyone who wants to know what the sea is doing before getting in. Coverage 60+ countries, 2,600+ coastal cities: Portugal, Spain, Italy, Greece, Croatia, France, Turkey, USA, Mexico, Brazil, Chile, Peru, Argentina, Australia, New Zealand, South Africa, the Philippines and more. Spearo is available in 9 languages. Some features require a Spearo Pro subscription. Subscriptions renew automatically through the App Store unless canceled. You can manage them in your Apple Account settings. The yearly Pro plan comes with a 7-day free trial; other plans have no trial. If you start it, cancel in your Apple Account settings at least 24 hours before it ends and you won't be charged. Forecast limits A forecast is a guide and it can be wrong. Check conditions on site, respect local rules and seasons, and never dive alone. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
