* And more!

Keep track of what your buddies are doing and where they're surfing. You'll be able to check out their stats as well and compare with yourself.

Constantly crashing, data fails to save


I had high hopes this new surf activity tracker would be everything it claims. It's not. Well the GPS side works ok but the supporting app is complete garbage. From the moment I installed it it kept crashing. I entered simple profile information...crash. I updated my low res profile pic...crash. There are some apparent neat features of this app to visualise data collected by Trace sensors, but the app is unbearable to use. Hope they fix the bugs soon or I'll be moving the the Rip Curl GPS watch that is more expensive but has less bugs and more convenient to use.

My friends surf like what!?

I love Trace. I use it mostly for two sports, sup surf and sup race, and being that I'm a professional stand up paddler, receiving the data for each gives me some really cool insight to what I'm doing out there. From the turning radius on sup surf to the paddle strokes per minute on sup race, it gives me info that I didn't have or know of before. I can also compare with other surfers or racers that I admire (which is cool) and I think one of my most favorite parts of it... I can compete with friends. After a session, even if my friends are halfway around the world we can compete for longest ride, quickest speed, etc. All we have to do is upload the files and bam. If my score gets beaten I'm always sure to hear it from the friend who did and get heckled by the others. It makes sessions that much more fun. Great product. Thanks Trace!

I've had Trace for a few months now. It's a very cool concept, but I will say that the design is in its early stages. I ran into several issues in the past with my data being incorrect or just not loading at all. It took some time to communicate with the support staff and get it worked out. Overall, the idea for the product is great and the device itself is small and compact. The new updates are fixing some of the bugs and it is worth having overall. This will definitely be a 5 star device and app with a little more refining and I believe that the trace team will accomplish that very soon.
