I am currently using the SURFR app and previously the woo 2 for a short while before it died. In my experience the woo2 was a bit random, it would report the highest jump from a part of the session when it certainly didn't feel the highest. With the SURFR app it tells me the jump height right after the jump and it feels quite consistent and usually when it felt higher it reports higher. On my latest sessions all my highest jumps have been the same within about half a meter with the surfr. I haven't used the woo 3. Has anyone else tried both?
According to this review the Woo3 was 1-2 meters higher on 70 % of the jumps.
I have a Woo 3 and I also use the Surfr App with the Wetsuit mode. The results are close in my case, but I do not jump very high.
The Woo community is more active and offers more interaction. However, the Surfr App is free and offer nice features. I will continue to use both, as long as my Woo works.
With the SURFR app it tells me the jump height right after the jump and it feels quite consistent and usually when it felt higher it reports higher.
With WOO 3 you can get a watch and see the jump height and a lot of other information right away. Or you can use an old Android phone and install my Woo Screen app (https://play.google.com/store/apps/deta ... reen&hl=en) - it can speak up WOO 3 jump height without using the watch.
Surfr have struggled a lot to get going. I really hope they do, but they made one mount which I guess kind of worked. Then they made an upgrade which they later figured out didn't. Then the "fix" for the second mount has been delayed and I guess delayed.
Not surprising for a "start up". Especially since Surfr seemed to be some friends or something just making an app for a phone then it just went from there.
Personally I am "loyal" to Surfr because I like that they pushed development. To me Woo got stale - and only started reacting to Surfr when they saw some competition coming (obviously I cannot know that to be true, but from the outside it looked like it).
I love the simplicity of surfr. Just put in in a drybag around your neck and start jumping. They've tested both and it's not less accurate. Only you can't see the height realtime, which I actually prefer to stay "in the kiteboarding moment". No need at all for the board mount. Also their vision on data is quite cool, they just launched a lot of spot insights based on user data. Like rating, prevailing wind direction and speed.
