Ratings and Reviews
Swimming doesn't work
App is promising. While running and cycling work fine, logging a swimming workout fails. It says "Please allow Zx to 'Write Workout Data' in Health and try again.
By the way your support website is just a placeholder site. Might want to update that.
In addition to the above bug, to be useful during swimming, the alerts would have to be different patterns for above and below zone, and they'd have to be constant. For example, short quick vibrations if below zone and long slow vibrates if above zone. The same kind of constant and differentiated alerts would be useful in other situations (e.g. watch under your sleeve or glove) but especially in swimming when it's not practical to look at the watch face during a lap.
Developer Response ,
Hello headquire! Thanks for trying Zx. We are now aware of the pool swimming issue and are working on a fix for it. The issue is that we aren't setting a pool lap length for the workout so it can't be started. Hopefully we can get a fix for that soon.
Also! We're going to be developing an app dedicated solely to swimming and we appreciate your ideas. If you like to message us with any features or idea you'd find useful in a swimming app, we'd love to hear it! You can reach us at support@oversphere.net.
Best,

PS thanks for letting us know about the website, it should now correctly again be redirecting to our Facebook page. :)

4 stars. Would give 5 stars if the colored bars in the workout graph also displayed the target heart rate zones like the Polar Beat app. does.

Rip off
I was looking for something to exactly what this app should do, if it worked! But the studio (self-created) workouts don’t work! They don’t sync with your phone and when you open it on your watch it just spins.. waiting for you to start the workout (that does not appear) on your watch. Biggest waste of $15. I tried to contact support but my email was bounced back and the link from the App Store leads to a page that says coming soon. I’m going to try to request a refund because this is so pointless. A shame because I would have gladly paid the $15 for something that worked as expected.

Hi BlondieTess, I’m very sorry to hear your experience with Zx; definitely not want we want our users to experience!
Emailing support@oversphere.net should create a support ticket in our system for us to help you further. If that doesn’t work, please contact us on Messenger at https://m.me/oversphere
Hopefully we can get you up and running!
Best,
Jeff
