Windsurfing on Maui is exciting and beautiful. As a former Tornado catamaran racer, I'm excited about fine tuning gear to get the very best performance. The Waterspeed app is useful in so many ways. I used the free version for a while, but found it became a regular part of my routine, so opted to buy in and get even more useful info. It tracks my start and stop times (I run it from my Apple Watch), and shows a track of my session with the point of highest speed pinned on it exactly down to the second. This allows me to see things like average speed, peak 2 second speed, highest sustained 10 second speed, etc. A new feature allows you to turn on genes. By touching your path on the map, you can see entry and exit speeds and directions, and use it to improve your techniques. Change fin, change downhaul or outhaul settings, mast position, boom height etc and see real time differences. Also summarizes your session and keeps an ongoing diary.Max (the developer) is very responsive to questions and suggestions, too. As a former small boat racer,,5)3,stopwatch start function would be useful, too. He has set it up to cover a myriad of different sports--pretty much anything you could do in the water, including foil sports, canoeing, kayaking and even swimming. A really terrific app if you're any kind of a water athlete. And I can't emphasize enough how much Max understands the challenges of using an app in a constantly changing, wet environment and how responsive and in top of things that he is.If you're a water person, this app is a must have!

I am fairly active individual and have tried many apps over time to track my Sailing, kayaking, boating, paddleboarding. I am not one to pay subscriptions but this is so reasonably and has most items from other apps I am looking for when I am on the water. We moved 4 yrs again to a lake area and my other gps app, although it works is no longer supported and I hate the interface. I realized my apply watch workout app is sadly lacking anything really useful. I admit were a few small things but the support on this app has been great and all my issues resolved. This works with Apple health and my Apple Watch. I love the interactive map and all the charts and data. I have used it mostly for paddle boarding and once for sailing. Kayak season is coming so I will give it try shortly. I like the Stroke data, now that decimalPlace is fixed. I will be trying the live tracking next time I go without my husband. I have tried another popular app but it is much more expensive and less features. I have. Few things in my wish list like Total strokes for the workout in addition to the splits. I also think for boating and sailing. Waypoints would be nice and automatic pause when stopped for a period of time. Too difficult to fiddle with watch while paddling to remember to start and stop. I give it an A overall.

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.

This is a fantastic app to keep track of your performance when doing water-based sports, regardless if it is sailing, windsurfing, kitesurfing or paddle sports like kayaking, rowing or SUP’ing. I use it mostly for kayaking and surf skiing. The app on the Apple Watch can be used stand-alone to track speed, heartrate, distance etc. The app then syncs to the iPhone app automatically when in reach again. This means that I do not have to take my phone on the water. On my iPhone and iPad I have access to the exact GPS route on a map, speed and other statistics I collected while paddling. The PRO version is also well worth it, it gives you access to detailed weather, wind and tide forecasts and provides seamless syncing with Strava (your route and stats get uploaded to Strava with the correct activity classification automatically). It works very well; the support is outstanding, with frequent app updates and feature additions.This is a must app for anyone serious about water-based sports!
