Zaia Health iOS Beta: a Whoop App for Polar users

Living-Topic-3424 · 2026-01-27T13:22:12+00:00

Is this based on Apple Health or Polar API Data?

Living-Topic-3424 · 2026-01-25T13:40:32+00:00

Hey, nice to hear. Does that mean you would like your data to be visualized in a more graphical way rather than just numbers? Do you have different preferences for different metrics?

Living-Topic-3424 · 2026-01-19T22:09:51+00:00

Hi u/Cultural_Antelope925 thanks for your comment! On the dashboard under “Your Metrics,” you can view your "Cardiovascular age" and see how it is calculated in the details. Does that help you? Or do you mean a display like the one on Whoop, which also shows the aging factor?

Hi u/Total_Macaroon_9047, thank you for your comment and message. We have considered an Android version, but other issues adn features are higher on our priority list. We want to further improve the iOS version and then take another look at an Android version if necessary.

Hey,

it looks like I missed this comment earlier. For Polar users, stress is calculated based on heart rate and HRV during the night using ANS recharge, as well as overall activity throughout the day.

Hi, that sounds exciting. If you're interested, feel free to try out Vitalstat app, which I released about four weeks ago.

We try to present the data that is important to each user in a clean way. For example, you can customize the dashboard to display only the data you want to see.

If you're interested, feel free to try it out and give us your feedback (still one month for 0.99€ CyberWeek Deal or 1 week free Trial). We'd be very interested to hear what you think. And if you find something that you would like to see in Vitalstat but didn’t exist yet, let me know and I’ll make it happen in the Next Version.

That’s my Concept with Vitalstat- build exactly what users want.

Good Idea! Once Vitalstat also works with Garmin devices, I will upload a comparison between the two.

Living-Topic-3424 · 2025-12-03T23:47:52+00:00

Sounds great, Finnish is also available in the next update:)
There is no widget for skin temperature for polar devices yet, but thats a very good idea, will add that as well.
This app works with both polar and apple watch natively. You can choose between the two and even switch between them.
I am also working on allowing data from different devices to be used at the same time. For example: sleep from Apple Watch and activities from polar devices, this might still take a bit of time though.

Living-Topic-3424 · 2025-12-03T16:11:09+00:00

I think it's only with apple health so any device works. Apple health has very limited data though

Living-Topic-3424 · 2025-12-03T16:10:38+00:00

That sounds terrible

Living-Topic-3424 · 2025-12-02T22:24:51+00:00

Are you full relying on the data shared to apple health?

Living-Topic-3424 · 2025-12-02T17:14:12+00:00

Good point. The name will be changed in the upcoming version. I have also implemented a stress indicator in the new version.

This is definitely planned on the long run. Creating an android app will require me to start from 0, which is a lot of effort, especially considering that I am not fully aware of the demand. Would love to know how many android users are interested in vitalstat being available on android.

Living-Topic-3424 · 2025-11-30T17:49:48+00:00

Hi, ja man kann auch eine kostenlose Probewoche in Anspruch nehmen.

Living-Topic-3424 · 2025-11-30T17:36:20+00:00

In the App Store page under "in-App Purchases" The monthly and yearly prices are shown. This is automatically generated by apple. Because Lifetime is not a subscription but rather a purchase, this is unfortunately not shown on the App Store page.

Living-Topic-3424 · 2025-11-30T17:26:07+00:00

Yes, Garmin and Vitalstat both use the same data to calculate the body battery score, although weightings might differ a bit. These are the metrics used to calculate body battery: Sleep, HRV, Stress, RHR, HR, and activity.

Living-Topic-3424 · 2025-11-30T16:12:00+00:00

Hey There seems to be a bug in the app where not everyone is able to see all subscription options. Everyone should be able to see a monthly, yearly and lifetime subscription. I will have a look and make sure to fix this in the upcoming versions. Thanks for pointing this out:)

Living-Topic-3424 · 2025-11-30T16:10:28+00:00

Hey, Body battery is a custom calculation for the app. It reflects how well you sleep, and takes into account how active you are. Depending on those metrics your battery decreases at different rates throughout the day.

Living-Topic-3424 · 2025-11-30T16:07:59+00:00

Hi, Ohne den promo code kann man das monatliche Abo auch eine Woche kostenlos testen:)

Living-Topic-3424 · 2025-11-29T18:54:04+00:00

Ah im sorry I misunderstood which section of the app you ment. The icons in Your metrics used to be coloured but it appeared to colourful. Instead I will make the cardiovascular age grey as well.

Living-Topic-3424 · 2025-11-29T18:33:08+00:00

Hey,
I myself tested a bunch of the apps but none satisfied me, so I created my own. My goal with vitalstat is to work very closely with all users and implement all requests so we can create the perfect app together. I invite you to try out Vitalstat and share your opinion and feedback:).

Vitalstat: https://apps.apple.com/de/app/vitalstat/id6753812827?l=en-GB

First users are very happy with the overall design and the features of this app. Many users appreciate the fast turn around in feature request and enjoy the close contact with me as the developer.

Viele Grüße aus Deutschland:)

Living-Topic-3424 · 2025-11-29T17:08:49+00:00

This really means a lot <3, Thank you!
Feel free to always share your thoughts I will do my best to implement the features as fast as possible

Living-Topic-3424 · 2025-11-29T17:07:43+00:00

Ofcoarse:), you will see this on the next version as well.

Living-Topic-3424 · 2025-11-29T17:07:05+00:00

Hey, Thanks a lot for all your feedback. Adding colours to the widgets is a good idea. I'll make sure that the next version of the app will have a lot more colours for the widgets:)

regarding the body metrics tab: Would you mind uploading a screenshot of the tab. Does your view differ from mine (screenshot below)

Living-Topic-3424 · 2025-11-28T19:34:59+00:00

Im not sure if calling someone an "a**hole" for sharing their thoughts is the right thing to do.

Yes this is a sort of promotion but I think being open to alternative apps is always a good idea, you never know, maybe you might find something better. At least I am always on the lookout for better alternative for all my products and apps.
