TideDeck: Tide Times & Charts

About

Tide times for anywhere on Earth, worked out right on your device. No signal, no account, no ads. TideDeck gives you the day's highs and lows, a live water-height curve you can scrub minute by minute, and a year-ahead planner, all computed offline. Along US coasts it draws on 1,302 NOAA stations. Everywhere else, it models tides from a global ocean model, so you're covered on any shoreline in the world. SEE THE TIDE, MINUTE BY MINUTE - Current water height and whether the tide is rising or falling - Next high and low water, each with a live countdown - An interactive curve you scrub by hand, with haptics that tick at every high and low - Today's high and low times and heights in a clean table - Day and night shading, a live now marker, and HIGH/LOW labels ANYWHERE, OFFLINE - Modelled tides for your exact spot, anywhere in the world - Exact predictions at 1,302 measured US stations, clearly badged - No signal needed, it is all computed on your device - Search by name, state or ID, find the nearest, save favourites PLAN AROUND THE WATER - Browse the days either side, then jump straight back to now - Best days ahead surface the lowest and highest water for a swim, a launch, or a rockpool - Week and month charts show the swing from springs to neaps - A tidal character card reads the type and spring range of your spot at a glance SUN AND MOON - Sunrise, sunset, moon phase, illumination and day length - An interactive scene showing how the Sun and Moon align to shape springs and neaps BEAUTIFUL AND LEGIBLE - A premium interface, contrast-checked in light and dark - Five themes, plus a high-legibility reading mode designed with dyslexic readers in mind - Heights in metres, feet, or a mix TIDEDECK PRO (one-time purchase, no subscription) - Full-year forecast horizon with an offline year scrubber - Safe-window planner: set the water depth you need, for your draft, a sandbar, or a swim, and it finds the windows, always erring on the side of less water - All five themes One purchase, yours forever. Stations, today's tides, the live curve and the Sun & Moon scene stay free. HONEST BY DESIGN TideDeck predicts the astronomical tide using harmonic synthesis, the same method behind official tide tables. It does not model weather: wind and pressure push real water above or below any prediction, so every height carries a confidence band. Measured US stations are typically within a few centimetres; modelled tides elsewhere are clearly badged and coarser near complex coasts and harbours. For planning, not for navigation. Always cross-check official sources on the water. EULA: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
