Tide Charts for iOS
About Tide Charts
New: Brand new UI, tide alerts, satellite radar view, updated station map, updated Apple Watch app, updated tidal forecasts, and more!
Finally a beautiful and simple way to view tides on your mobile device! In addition to worldwide tidal estimates at tide stations, you can see the lunar data, weather forecast, and current radar making your next outdoor adventure as easy to plan as possible.
By default, the application will pick the closest tide station to you, but picking a different tide or weather station is as easy as viewing a map of your current location. You can also setup and quickly switch between many stored favorite stations if you need to.
No internet access while outdoors? No problem. This app has been designed to give you tidal and lunar predictions without internet access!
Tides at a glance
• A clear chart of the whole day, with the current height marked and daylight hours shaded (lunar rise and set is the small gray bar on the bottom)
• The times and heights of every high and low tide
• Swipe left or right to move through the days, or pick a date on the calendar
• Swipe down to see sunrise, sunset, moonrise, moonset and the phase of the moon
• Subscribe for tide alerts that notify you before a chosen high or low tide
• Home Screen widgets with today’s tides and the next tide
Worldwide Tidal Stations
• Nearly 8,000 stations, from the coasts of the United States and Canada to Europe, Japan, Korea, Taiwan, Southeast Asia, Australia, New Zealand, South America and the Pacific islands
• Find the nearest station with one tap, search by name, or browse the map, with satellite imagery when you want it
• Keep your favorites one tap away
Adjustable Height to Match Your Local Tide Table
• Heights use the datum your local charts and tables use: MLLW in the United States, chart datum in Canada, Japan and Korea, LAT in Europe and Australia, MLWS in Peru and Ecuador (or you can choose your own from Mean Sea Level, MLLW, MLW, MLWS or LAT)
Weather and Radar
• Weather forecast is included for the station’s location, with wind, temp, precipitation, and the day’s high and low
• Animated rain radar with a scrubber, so you can see what is coming
Apple Watch
• A full-screen tide chart on Apple Watch: turn the Digital Crown to step through highs, lows, sunrise, sunset and moon times, or drag to scrub through the next 30 days
• Complications for every watch face, from a tide gauge to a chart of the next 24 hours, in the color you choose
• Your favorite and nearby stations, with the current height and the next tide
Tides is free with ads, however we do offer a one-time purchase to remove them if you would rather a clean distraction free experience.
Download Tide Charts for iOS for free — the latest version (3.2.1) is now available for installation on your iPhone or iPad.
What's New in the Latest Version 3.2.1
• The status bar, with the clock, signal and battery, is back at the top of every screen
• The calendar builds its months in the background, so it opens at once and stays smooth while you scroll
• The tide chart’s scale now follows the station’s tides through the seasons
• Faster and more stable, with a fix for a crash during background refresh
Apple Watch
• “Tides Classic” brings back the original complications in every slot: the H/L dial with the next tide around the bezel, the next tide’s level and time in the corner and one-line slots, and the three-line station view
• The standard complications show the next tide’s height again, not just its time
• The current level now matches the app right after the complication refreshes
Tide data
• Portugal: heights are now above the Zero Hidrográfico, matching the Instituto Hidrográfico tables (they were about 0.25 m low)
• All 19 Portuguese main ports now follow the official Instituto Hidrográfico predictions, and Setúbal (Tróia) is a new station
