Gyre is a fun, map-based app for seeing what's going on near or on the water — tide predictions for coastlines worldwide, global ocean currents animated right on the map, and a reading for any spot of open water you tap. The map is the centerpiece — and it's alive. Wind streams across the surface, waves roll through at the real local period and direction, currents flow worldwide, and the Tides layer colors the whole ocean by the state of the tide. WHAT YOU CAN DO • Tap to read — turn on Wind, Waves, Currents, or Tides, then tap open water. A dot and a small callout read that layer at the spot you tapped. With Tides on, it shows the tide there: the prediction from the nearest tide station, or, out in open water, a model estimate (an estimate, not a measurement). • Tides layer — the ocean colored by the state of the tide, with tide station markers on the same colors. • Tides — the water level right now, not just the next high and low. Computed on your device from published harmonic constituents, so you can jump to any day, past or future. Charts, high/low times, and a 7-day forecast for thousands of stations, from Puget Sound to Tokyo Bay, the English Channel, and New Zealand. • Currents — worldwide ocean currents animated on the map, modeled by the E.U. Copernicus Marine Service. Speed and direction predictions at NOAA current stations (US), computed the same way as tides. • Weather — current conditions, hourly forecast, marine-zone forecasts, and marine-warning alerts with optional notifications. • Wind & waves — animated overlays you can actually enjoy watching. • Buoys — live offshore observations from NOAA buoys, right on the map. • Astronomy — sun and moon rise/set, phase, and altitude charts. • Search — jump to a station, a buoy, a beach, a surf break, or a harbor. • Widgets — the next tide on your home screen, per-widget station choice. WHERE THE DATA COMES FROM • Tides: thousands of harmonic stations worldwide, each with its own local time and its own chart datum. • Tide estimates away from stations, and the Tides layer: the FES2022b ocean tide model (LEGOS, NOVELTIS, CLS; funded by CNES; distributed by AVISO+), adjusted to nearby tide gauges. • Currents: worldwide surface currents from the E.U. Copernicus Marine Service; NOAA current stations (US). • Buoys and marine-zone forecasts and warnings: United States (NOAA). • Weather, wind, and waves: worldwide. BUILT TO BE PLEASANT • No signal needed for station tides — predictions are computed on your device, not fetched. (Map tiles, weather, buoys, the map overlays, and the tide at a tapped spot still need a connection.) • Light, Dark, and System appearance. • Your units, everywhere: distance, wind, temperature, tide height, pressure, and time format. • Accessible: VoiceOver, Dynamic Type, and reduced motion. • Private by design: no accounts, no ads, no tracking, and anonymous usage stats you can switch off. Gyre is for information and enjoyment only — it is NOT a navigation tool and no substitute for professional marine navigation. It's for the joy of watching the water. ## Key features - Interactive map with animated wind and waves - Offline tide predictions and 7-day forecasts - Real-time current speed and direction - Marine weather forecasts and alerts - Live NOAA buoy observations - Sun and moon rise/set times and phases - Home screen widgets for tide information ## Is Gyre safe?

Gyral Tides is a map-based application designed to display real-time information about tides, currents, weather, wind, and waves. It provides detailed tide predictions and forecasts, making it useful for observing marine conditions. ### Does Gyral Tides work offline? Tide predictions are computed on your device and do not require a signal, allowing for offline use. However, map tiles and weather information still require an internet connection. ### What kind of weather information does Gyral Tides provide? Gyral Tides offers current weather conditions, hourly forecasts, marine-zone forecasts, and marine-warning alerts with optional notifications. This helps users stay informed about weather relevant to water activities. ### How accurate are the tide predictions in Gyral Tides? Tide predictions are computed on your device using NOAA harmonic constituents, allowing you to jump to any day, past or future. The app provides charts, high/low times, and a 7-day forecast for thousands of stations. ### Is Gyral Tides suitable for marine navigation? No, Gyral Tides is intended for information and enjoyment only. It is not a navigation tool and should not be substituted for professional marine navigation. ### What devices support Gyral Tides? Gyral Tides is available for iPhone and iPad devices. It supports features like VoiceOver and Dynamic Type for accessibility. ### How often is Gyral Tides updated? The latest version of Gyral Tides is 1.1, which was released on August 21, 2026. Updates typically address improvements and new features for the application. ### Does Gyral Tides have ads? No, Gyral Tides is designed with privacy in mind and does not contain advertisements. It also does not require accounts or tracking, and anonymous usage stats can be switched off. ## Version history (last 4 releases) ### 1.3 — 2026-10-20 Gyral Tides is now Gyre. Tap anywhere on the water to read it. With Wind, Waves, or Currents on, a tap shows that layer's reading at the spot. With Tides on, it shows the tide there, from the nearest station or a model estimate. The new Tides layer colors the whole ocean by the state of the tide, and tide station markers use the same colors. Wind, waves, and currents now sit on a soft color field, currents fade smoothly into sheltered water, and the map refreshes its forecast when you come back to the app. ### 1.2 — 2026-09-17 Ocean currents go global. Modeled surface currents from the E.U. Copernicus Marine Service now animate across the map worldwide, not just in US waters. Wind and wave animations have been retuned for a smoother, more realistic look. The map legend is now a simple tile grid, and Voice Control can now select search results and open every section. ### 1.1 — 2026-08-21 Tides go worldwide. Predictions now cover thousands of stations beyond the US — Japan, New Zealand, the UK, Norway, Iberia and more — still computed on your device, still working with no signal. Every station shows its own local time and its own chart datum. The map controls have a new look on iOS 26. ### 1.0 — 2026-08-17 No release notes. ## Apps similar to Gyre | App | Rating | Price | Category | | --- | --- | --- | --- | | [Slackwater: Tides & Weather](https://appshunter.io/ios/app/slackwater-tides-and-weather/id6785986784) | 5.0 (1) | Free | Weather | | [SAMUDRA](https://appshunter.io/ios/app/samudra/id6450824919) | — | Free | Weather | | [Air Quality Index](https://appshunter.io/ios/app/air-quality-index/id1296674639) | 4.5 (20) | Free | Weather | | [WeatherSentry](https://appshunter.io/ios/app/weathersentry/id1458549306) | 3.3 (38) | Free | Weather | | [EPA AIRNow](https://appshunter.io/ios/app/epa-airnow/id467653238) | 3.2 (579) | Free | Weather | ## Related topics [tides and currents](https://appshunter.io/ios/topics/tides-and-currents) --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
