## What is Absolute Tides?

Displays officially licenced UKHO tidal data on an annual basis without ever needing to go online.

The tidal data is contained in our annual data plugins and must be purchased using in-app purchases.

Once you have purchased the data, this app will allow you to view UKHO standard port tides up to a year in advance.

The app will also calculate secondary port tides using its own built in offsets. (The 'UK data 2016' IAP contains data for 38 primary ports and over 500 secondary ports, see our website for more details on coverage)

The main view is an 'At a glance' table view of each month's tides and tidal ranges.

Selecting an entry will display an easy to use daily chart view showing the tide height for any time of day and a tidal stream view showing tidal direction and speed at hourly intervals.

The Weather section downloads and displays the current Met Office Inshore Forecast.

Absolute Tides also makes anchoring easy by calculating the maximum and minimum tides beween the current time and any selected future date/time.

Note: This application will NOT work without at least one of our tidal data in-app purchases being installed. Please check that the tide data you want is available before downloading this app.

The small print:
For leisure use only.
Heights of tides can vary from those predicted depending on the prevailing weather conditions.
All data is given in good faith and is believed to be correct but we accept no responsibility for any consequential loss or damage arising from use of this application.
Secondary port data calculated using offsets will be less accurate than the UKHO standard port data.
This app is neither affiliated to nor endorsed by the Met Office.

### 5/5 — Wouldn't be without it, excellent app.

*2026-08-15, version 1.7.8*

This is one app i use all the time. And,with other corrobrative sources of info, rely on heavily. Both pre-trip planning and especially when at sea. Even more specifically, on the French side of the Channel & Channel islands, where tides are more dominant. You can very quickly determine in real-time the options for approaching a coast, and make the best choice. It can save hours of warming up the Planet,punching a foul tide. Would not be without it. Just wish there was a version that covered the full French Brittany & Atlantic coasts, or more, using the French SHOM charts. There is not.

### 5/5 — Perfect for me

*2026-05-28, version 1.7.8*

Our boat lives in the inner basin at Falmouth Marina, accessible for about 7hrs each tide. This App graphically shows me + or - 15 mins when I can leave or return to my berth. Invaluable. As a bonus it shows tides and weather. Of all the Apps on my phone, this is the most useful. Can’t think how it could be improved.

### 5/5 — No hassle app

*2026-01-22, version 1.7.5*

It just works - easy to use and value for money!

### 3/5 — Updated useless.

*2026-01-04, version 1.7.5*

Got to the end of 2025 then stopped. Did not move into 2026. No updates into new year…nothing. Where I was movement in car depends on tides. Remote no signal, so could not download new. Really inconvenient and annoying.

### 5/5 — Accurate - 1 improvement please!

*2025-10-28, version 1.7.5*

I have checked this app randomly against information from tide tables for a Solent standard port and it was spot on for height and times. Checked some secondary ports against  easytide.admiralty.co.uk and heights were pretty much bang on, and timings if different were by a few minutes. This was a lot better than a couple of other apps some friends had.  SUGGESTION: standard ports stand out in the A-Z ports list (they are capitalised) but once selected to show tide times there should be an indication whether we are looking at a Standard or a Secondary port. (The capitalisation is lost and I have not spotted another indicator)

### 5/5 — That’s what it says on the 10th

*2025-09-28, version 1.7.5*

This is a good app. I know some people are reluctant to pay, but why would you not pay for something that is gonna make life easier?

### 4/5 — Easy and quick to use, no frills

*2025-09-15, version 1.7.5*

Used for 2 years and good overall. Quick to see tide times and heights and tidal height at a particular time. Use of offsets is confusing, not well explained. Inshore weather forecast doesn't always download the latest info

### 5/5 — Really easy to use at sea

*2025-08-05, version 1.7.5*

So racing around the Normandy/CI coast we had the most sophisticated marine navigation equipment at hand. Often this amazing little app being so easy to use in real time is the one we headed for.

### 5/5 — Essential, particularly if single-handed.

*2025-07-05, version 1.7.5*

Outright my favourite tidal stream atlas app for these waters. Whether pre-passage planning, en-rte with an itinetary, or to tell you where you got it wrong if, for instance, you have given yourself the 'tourist special' in Guernsey on Springs. Not only saves time, if you get it right first time. But also gives quick look-ahead, if you are about to get it wrong in 3hrs time. Allowing a change to a more successful plan. Absolutely essential in my opinion. I buy a subscription every year, without hesitation.

### 1/5 — Newcastle Ports mixed up

*2025-05-22, version 1.7.5*

I used this app to plan a beach walk at Newcastle Co Down NI, (listed as a sub port of Belfast). We were almost cut of by the tides as the data was actually for Newcastle upon Tyne. 
I reported this serious and dangerous error to the developers but didn’t get a reply and the data is still wrong 6 months later.
