October 14, 2019 | Version 2.6.0

Love the functionality but the data is totally off. I entered Lat & Lon from Google Maps several times for a location far away. Widget updated but data has not changed and is completely incorrect vs tidal charts. I'm sure I have something incorrect. Would be great if it worked. fenix 5X PLUS

October 13, 2019 | Version 2.6.0

Practical and very readable app. Very good reactivity of the developper to the questions asked. The most beautiful dial of this type of app. I recommend

October 13, 2019 | Version 2.6.0

Nice idea. But you can't see from which station the data comes. There's apparently no station within 5 kilometres range. Service comes up with data from more than 100 kilometres away without warning.

October 4, 2019 | Version 2.5.0

The perfect complement for TidalFace. TidalFlow + TidalFace = Best combo ever.

Works perfect. Great job!!!

Glad it works for you! Thanks for the review!

Really nice and clean presentation which also works with widget glances. So well done it feels like it should be stock. Best would be to get tides from Garmin's internal calculation without phone...

Thanks for your kind review and rating, much appreciated. Unfortunately third party developers don't get access to most of Garmin's internal data. Garmin's tides is one of the restricted types of data.

September 15, 2019 | Version 2.3.0

Fabulous. Very well put together widget that gives clear - and accurate - data. The glanceable widget on a Fenix 6x is really informative and looks great too!

Thank you for the kind review! This is the first review regarding the F6’s new glance feature and I am thrilled that it is well received by users!

1/ not always coherent with datas from local authorities (Arcachon, France).... I wonder why 2/ Not available on Oregon 7x ?

Developer Reply
September 16, 2019, HermoT

I'm not planning on making it available for non-wearable devices. Sorry. As for the consistency of data, this is not the responsibility of this app. It uses a third party web service. You should contact the owner and consult him.

September 6, 2019 | Version 1.3.0

The best widget!!! (waiting for serie 6x) :-)

Quasi perfect but I need the values for the real time not only for low and hight tide

Please contact me through the proper channels. Your request makes no sense. The current time is displayed and the red line indicates the point in time on the timeline.

Good simple app. Seems to work well. I'm not getting sunrise and sets on a garmin 245 music as the graphic shows. Should I be setting something differently?

I was using a different widget that charged me $3.99 a year for information that usually wasn't correct when compared to online sources. I decided to compare the two widgets and I found the former was off again and this widget was spot on for the same location. Bonus is this widget is free. I'll definitely be donating to the dev. Great job!
