I use it for surfing and the main issues are that it does not accurately record each wave and it often confuses an attempt to catch a wave with a wave caught. Frequently it does not capture anything at all and what it does capture rarely transfers to the phone.This app feels like it is trying to do too much for too many sports. Some concerted effort on making sure that the basics work, like recording the data in the first place, and reliably transferring this to the phone, would go a long way to turning this app around. I keep it on my watch in the hope that the next update will address these; but as of August 2018 it hasn’t been updated for eight months. Hoping the developer comes back this at some point as it’s such a brilliant and useful idea. If it worked properly it would be an app worth paying for.

I have been using this app for about 2.5 years on my Apple Watch 3 w/ cellular for tracking Kitesurf sessions. I love it when it works but the app has many bugs and glitches that are incredibly frustrating. I have successfully tracked over 200 sessions on the watch however I have had the app fail probably another 50 times or more. What seems to happen is a few things - either the session gets recorded and when you end the session and the watch “processes latest session” the data gets lost or when I start a session it somehow ends during my time on the water. I always make sure to water lock the screen so it doesn’t accidentally end from the water. Even then - I get back to the beach and the watch is still water locked and just showing my regular watch face. All the data is lost. It’s terribly frustrating. I wish they would fix the bugs bc it would be a really amazing app if so.

Some information seems to work (speed, time, distance) sometimes it doesn’t (3 hour session I paddled 265,000m? I doubt it) and never once has it transferred to my phone. Even after the latest update that “fixed” that issue it still has yet to sync (and those sessions are lost, no tracking other than a short overview in activity). Upside it does time track waves so easy to check Surfline camera at that time then getting a rough guess. Doesn’t really track waves under 3’ though. I want to like this more, like a lot more. Group of coworkers have the app and want to get more metrics, specifically area surfed but at this point, open water swim may just be the answer. Would revise review if the app was fixed.

I like the app. It allows me to track sessions ona map and get a sense of top speed (average speed doesn’t seem to be accurate). It pairs with the phone after a session (need to be near phone when you stop the app). It sometimes takes awhile to sync and show up - not sure of lag, but a lot of data? Highly recommend to get a sense of speed, distance traveled and then pairs with Apple Watch to see heart rate and calories burned during a session- it logs it as a workout. That works well.I know it can be improved, but it’s a great start. It also lets you track others on a leaderboard and jumps too. That seems pretty incredible too - time of jump, Gs location etc. thanks to the developer
