Reviews of Zx

Great workout companion!

Really helpful for taking a look at hr data

Fantastic app!

I was looking for an interval timer for my own HIIT training that could also pair with my coros armband to show my heart rate.

Paying $14 for this app seemed like a no-brainer when the cheapest watch I could find to show my heart rate was $180. Now I get to see my interval timer and heart rate in the one place. It works perfectly with my coros armband and make sure I stay in the zone during night intensity intervals (while not pushing too hard above my range). Thanks for making such an intuitive and affordable app with great functionality.

Custom and community workouts not showing on my watch

I’m not able to use the custom and community workouts after paying for this app because they don’t show up on my watch. 😕

Response from developer

Update: Hi Sentha, we have just released a fix for the issue; apologies it took longer than expected. Please be sure to update to version 1.6. If you have any further issues, please reach out to support@oversphere.net Original response: Hi Sentha, we just responded to your support request. We are looking into the issue with workouts not syncing quickly to the Watch. They should eventually transfer over, it’s just taking longer than it originally did. Best, Jeff OverSphere Support
