Great app

I purchased the pro version which allows you to set a count down timer for the start of a race. When I race I-20’s we use a 5 minute starting sequence. When I race windsurfers we sometimes use a 3 minute sequence. You can choose any length you like. It then starts tracking you while the time is counting down for the start while tapping you on the wrist when the start is getting close. It drops a pin on the map when you start the starting sequence and then drops a pin on the map when the flag go up “the actual start of the race” then drops a pin when you finish, which you have to press the stop buy when you finish. It lays the tracks down on a map with color indicating your speed. FYI, it shows the map stuff on my iPhone when I get back from sailing. This was all tracked with the Apple Watch 3. I can also easily send all the info to my iPad using airdrop. For me, it’s a great app for racing sail boats and windsurfing. Really easy to use. I Highly recommend it. I don’t usually leave reviews, but I felt I had to because I like this app so much. Can’t wait to try it out this winter when I go Iceboating and achieve speeds near 70 mph.

Essential for Sailers

Wow!! Do I like it and then some!! I sail on the Charles River and started to track my sailing late 2017 and found an app that did it pretty well. I record about 28 trips and then I found Waterspeed. I am instantly impressed as I ONLY need my Series 3 Apple Watch to record my sails. Previously I had to take my phone and watch to record trips. With Waterspeed I can see my trips played back with a visualization of my HR - Speed - Time - Heading. So cool! Waterspeed also uses colors to indicate your speed on a map (green, yellow, orange, red). I have 4 sails with Waterspeed and each time I’m more eager to look at the results and see where I had speed on the sail and how I performed. Awesome!! The data that is gathered is complete. Each sail tracks duration, distance, wind speed, avg speed, top speed, best speed 10 sec, best speed 20 sec, best speed 500m, best speed 1km, best speed 1nm, HR min, HR max, HR avg, calories, heading, and location. Also, I did purchase the Pro membership. BTW there is start timer too. Wow!

Great app for the sailor

I really like the pro version. It’s worth every penny. I sent in a request to add a feature that enables you to select a location other than your current location to monitor for weather / wind forecasts, and I got favorable feedback. I used it today and it is the best deal I have found. I haven’t raced with it yet, but it really helps you see how changes you make affect your speed and performance. It really keeps me in tune with the current conditions and performance.
I am able to change the location where I want to monitor the wind and weather forecast, but I still don’t know how to change the default location, from my current location to a desired location. At any rate, Waterspeed is the ultimate app for the sailor! The pro upgrade is definitely worth it.
