Went out today for my first swim with Open Water Swim App and it worked really well! Stats like pace and distance seem much more accurate than other apps I’ve tried and it was good fun to be able to share a beautiful visualization with friends and family. It was also eye-opening to see how much I swam off-course. Will definitely return to the post-swim stats and maps to gauge progress. Overall, really pleased and recommend highly.
Accurate open water swim track, nice display

The swim track is the most accurate I’ve found for lake swimming. There are occasional glitches related to poor gps reception on my Apple Watch beyond the ability of the algorithm to correct (such as when smoke from Quebec fires was distorting gps signals), but it’s usually quite accurate. I had a question and the app provider responded almost instantly.
Best open water swim App!!!

I’m an avid open water swimmer in Montana and this is by far the most helpful app that I have ever used. Love the temperature data as we usually start swimming around 47F in the spring and our lake only warms up to 74F by August so I am always curious what the water temp is while I am swimming. Only big suggestion would be a way to upload to Strava, then the app would be perfection!!!

The apple watch has a built-in open-water workout but I think it's totally worth the cost. I'm really enjoying it and set it up so it starts from my action button. I highly recommend it if you love open-water swimming 🙌🏊♂️🤙
