How to fix Qardio Heart Health app connection issues on iPhone?

Curious to know why the iPhone 8 should work, I just tried it on my old iPhone 7+ and got the usual "The Qardio service cannot be reached message"

Further comment on the Xr working with Qardio: I disconnected wifi and the phone still allowed access to the app. It's like how are the aliens feeding off the mothership...kinda.

Hmmm, yet you say you no longer have celluar service for this old phone either?

Wish I could help, but I don't have an iPad to test the Quardio app on. Good luck sir.

Could you detail how you did the pairing? That would be very helpful.

Thank you, your work around worked with my apple watch and I will attempt to connectthe Apple health link as it seems it is an option for record.

Have not been able to make the connection to Apple Health, but the watch is keeping a history by date with all cuff readings.

if anyone can figure out a way to make the Health link please post it.

This is the way to have access to the Qardio Cuff, it's a work-around for now and the best process to date. I'm surprised Apple didn't buy Qardio.

What is the way? I don’t see any information nor links to support your claim??

Unable to contact them at all

Thank you a thousand times! This works for me in August 2025, awesome sleuthing!

That’s awesome, well done, is there anyway you can send a TestFlight invitation? I’m in NZ so the app isn’t available for me, I’d love to test it out though

Any plans for submission to the Canadian App Store?

I have been using my watch to take readings, but could not make the transfer to Health. This solves that problem.

Thank you!!
