Great tide app

Stephanie Krieger

I live in western NC with a second home in Cape Hatteras. With hurricane Irene scheduled to hit around my Cape home about 10pm or so, I was anxious to know when high tide would be coming. None of the other tide apps out there could do what this does. I was able to set the tide watch dial to precisely the time I wanted at 10 pm this coming Sat. night (3 days). The watch indicated exactly what the tides would be at. Anxiety gone. Also, watch seems to have all the secondary areas which I travel to. But its real nice to be able to plan my fishing trips and know exactly what the tides are at a particular hour at anytime in the future. Watch dial is very intuitive once you understand it. I have several other tide apps. Save yourself time and money. This is the best one out there. Nice job.

Simple and Sophisticated -Great App

DJB Miami

Really great app for anyone with a nautical interest - fishing, diving, boating - all of which interest me. Also good for "lunar-ticks" i.e. anyone interested in the phases of the moon and moon rise/set and sun rise/set. I like the simplicity of this app, even though it is quite sophisticated. The GPS of this app accesses government data bases to quickly tell you the current state of ocean tides at your desired port, or, for that matter, virtually any port anywhere in the world. I haven't seen anything else quite like this. It's also a great clock, in an easy to use and easy to see wristwatch format, which I prefer. Finally, this app is easy to set and maneuver to a variety of desired visual forms. I think it's pretty reasonable for what you get. Enjoy it!!!



I am a swimming pool contractor in south Florida. When we excavate at the beach area we always have to deal with the water coming up. Since I got this app. I already saved big money by preparing my crew to do the steel work and order the concrete trucks just before the low tide. By the time the high tide came we were done, the concrete was set and I did not have to waste money for pumps and my crew sitting and waiting for the low tide. This application is simple to use and is accurate because it shows so many locations. In the past we always had to wait for hours because the tide locations that were available were so far from our actual location.
Great tool for contractors. 5 stars hands down.
