Should I go now? Let the tide answer.
TideCast is a tide and sea-weather app for anglers and fishers. Tide data is bundled on the device, so tide levels, tide phases and sunrise/sunset keep working even with no signal on remote rocks or at sea.
■ Tide at a Glance
A go/no-go signal, current tide level, flood or ebb state, and a countdown to the next high/low tide — right on the home sheet.
■ Tide Timeline
Tide curves for today, tomorrow and the day after, shaded by day and night. Scrub with your finger to read the level at any moment.
■ Offline Tide Engine
Official high/low tide tables for 79 Korean stations are bundled in the app. Forecasts work fully offline, with harmonic calculation as a fallback where no table exists.
■ Local Tide Numbering
Supports Korea's traditional 7-mul (West Sea) and 8-mul (South Sea) tide-day systems.
■ Sea Weather on the Map
Wind, waves, temperature, rain and clouds as map overlays, plus typhoon tracks, point forecasts and measured water temperature.
■ Fishery Zones
Village fishery, aquaculture and set-net zones on the map, with an alert when you enter a village fishery area.
■ Tide Alarms
Get a heads-up before low tide for departure timing, and a rising-tide warning to avoid getting stranded on the flats. Optionally receive a morning summary of the day's tides on your chosen tide days, with a night-quiet option.
■ Foraging Mode
One tap schedules a full alert set around low tide (30 min before → low tide → water rising → check your exit). Alarms fire even when the app is closed.
■ 14-Day Tides & Home Widget
Scan two weeks of tide days, high/low times, tidal range and sun times at a glance, and check today's tide from a home-screen widget without opening the app.
■ Share Card
Generate a one-image card with today's tide curve and high/low times to share with your fishing crew.
■ Catch Diary
A fishing log that auto-stamps the day's tide and conditions, helping you find your own bite pattern.
■ Sun & Moon
Sunrise/sunset times and moon phases for planning your trips.
