Utter crap

May 22, 2019 | Version 1.22-upd6

I Love it! Its a shame that the worldtides website (where the data is sourced) charge but that is no detraction from the app developer. Only thing I would like is a graphic representation of where in the tide cycle we are currently.

Hi, glad you like it! For the graphic representation, have you tried “Tidal Graph”?

March 7, 2019 | Version 1.22-upd6

Doesnt work on my Fenix 5X. After initial GPS signal look up i get Network Error - 104! garbage. Will request funds refund from my bank institution if this is not resolved.

Will not work with my fenix 5s. Get a not compatible button error, it won't even let me change settings without getting the error.

Looks awfull. Hard to install. Worldwide registration only covers 100 lookups then payment is needed. These data are not that important to me

Costs 3,99 €/year for 1000 credits and 1 credit per prediction. Looks good, but haven‘t tested it.

Hi Martin, just to be clear, I wrote the Garmin app but I don't own the tidal data at The app is free and I don't earn any money with it. When I released the app the data at was also free. Since then the owner and license model changed. As far as I can see from the site now ( you get one month of 100 free credits to make API calls. After that, credits cost $1.99 per 1000 credits and subscriptions start at $0.99/mo. Bulk pricing is also available for $0.10 per 1000 credits.

I would have given it Great if I had the option of removing the meters, because it is too much information cramped in on the fenix 5 screen

Your app is good, but as other pointer out, without the ability to change the Datum, it is more for a FYI than a really useful tool. It seems you use the standard MSL, while in my country, we use the LAT, so any option to let us select it (in the settings of the apps) would be really welcome. Thanks

This widget works on my FR645 when the graph widget doesn't, but the information is clear and useful. Thanks!

April 16, 2018 | Version 1.22-upd5

Need to be able to select datum or the numbers are meaningless sadly.

Most useful widget I have. Love it. Just lately been getting a network error - 2 when trying to sync. Any ideas?

Would be nice to be able to select Chart Datum and a specific port. Tide flows are based on major ports - not the closest port.

Data seems to differ from my local tide charts plus no way to switch to Uk Chart Datum, which means the info shown is pretty much useless with local charts!

December 12, 2017 | Version 1.22-upd1

Decent app. Correctly detects and obtains my local tidal information as confirmed with worldtides webiste. Unfortunately however, I cannot view the values correctly on my Fenix 5 due to overlapping text. Can the font size be reduced or amended to eliminate this issue?

Anyways for the edges not to be cutoff? Other than that, I love it!

December 2, 2017 | Version 1.22-upd1

Good widget but it could be better if you could improve design. Design is poor. Fenix 5x

November 13, 2017 | Version 1.22-upd

Can we please get an option to change the datum in the settings?

Good would go to great if you could set datum to LAT for Australian use as the figures it gives are really not of any use. Otherwise concept and data in the app would be great.

October 9, 2017 | Version 1.22-upd

Looks good on paper but useless as it shows "network error 104". No bluetooth connexion activated as I only conect my watch with a wire to my laptop. Any other suggestion to fix the bug?

Roar Håkonsen

I receive "Invalid Tides API key!". Do I need to do some additional steps?

Good would go to great if you could set datum to LAT for Australian use.

September 18, 2017 | Version 1.22-upd

Works well. Review would go from good to great if it had an option to set the datum. I understand this is possible from Worldtide. In Australia we don't use the MSL datum, so the numbers the app returns are meaningless. I also note that it doesnt quite fit on the screen of my Fenix 5s but that is only minor.

Awesome app. Worked great in Turks nd Caiscos but when I am in Chicago, cannot find data (since there is no tidal data within 100km) the Api returns {"status":400,"error":"No location found"} Would it be possible to have a 'default location' setting in the app where I could manually enter gps alternate gps location for that case so I could see a tide table even if I'm not in that location , for example I could put my default as 'Turks and Caicos' or my next vacation spot :)

Does not work on fenix 5s: “des returned error 40“

Sorry, no statistics available yet.
