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. 😕

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

Good simple interface-some iwatch sync issues

Love the clear interface on the app. Can’t seem
to sync studio and community workouts to my iwatch however.

Hello Bents76! Thanks for using Zx! We are aware of sync issues users are having and it not being as fast as it used to be. It may take awhile but workouts should eventually sync to your Watch. We are working on that and hopefully we can get a fix out soon. If you have any other issues or feature requests, please don't hesitate to reach out to support@oversphere.net. Best, Jillian OverSphere Support

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.

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

Eh

I got this app thinking it would give me realtime workout info on what zone I am in and for how many minutes. It’s just like all the other apps. you can only see what zone you are in at that exact moment. It’s not realtime info (the kind you can use to guide your workout

Hey Biltzzz, thanks for trying Zx! If you wouldn’t mind reaching out to support@oversphere.net we can get this logged as a feature request and get it into the app the upcoming release. Best, Jillian OverSphere Support

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 OverSphere Support

Support did not respond

I contacted support about the zone categories double the amount of time I worked out in each zone. I sent a screen shot showing that I worked out 6 minutes in the intensity zone according to my custom heart rate and it recorded over 12 minutes. I requested help and the answer was “crickets”…I’ve been totally ghosted.
I would have rated the app a 4 star, otherwise.

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.

Hi wingnut, thanks for the review! If you could reach out to support@oversphere.net with more details about your feature request, we may be able to get it into a future update. Best, Jillian OverSphere Support

A good heart

A great app to help with working out within specific heart rate zones, I really like the create custom workout facility, as well as the heart rate routines provided.

It was a bit fiddly figuring out why it wouldn’t connect with my Apple Watch, but issue resolved when I turned off the Bluetooth within the app settings.
Thanks for a very useful app 👍

Watch complication of Z Score please

Watch complication of Z Score please

The Zx score on the watch doesn’t match with the fitness level. For example, if I change to level 1, the iPhone app seems to be always at level 3. Please fix, thank you.

Problème

Je viens de me rendre compte. Que ma montre n’est pas compatible avec votre programme. J’ai un garmin. Il y a un autre façon de se connecter?

The app does nothing special that the normal Apple Watch workout app does not do. It’s designed poorly, there are few glitches. Do not bother buying.

Zx allows you to monitor your heart rate zones during workouts and how long you've been in each zone. It also offers guided heart rate training sessions created by professional trainers. Paired with the Zx iPhone app you can create your own training sessions, monitor your progress with heart fitness trends, customize your heart rate zones, see detailed stats for each of your workouts, and download training sessions created by other users. We hope this helps you see the value Zx offers over the Workouts app. If you have any concerns, please don't hesitate to reach out to support@oversphere.net and someone will help you with any issues you may have.

Resting Heart Rate has improved

Been using this app now for a couple months and my resting heart rate has gone down by quite a bit. My doctor was impressed!!!

Awesome app!

I’ve been waiting for something like this. The ability to make my own workouts is something missing from other zone trainer apps I’ve used. The watch interface is slick and gives me everything I need. Plus the ability to download other users creations is great when I need inspiration. Support is great with fast communication when I had a question. Definitely looking forward to seeing how the app evolves!
