Doesn’t work, don’t waste your money

This app doesn’t work.

Doesn’t work

Doesn’t work, says connected to watch but does nothing.

IPhone 17 Pro Max - Does not work

My watch goes back and forth between telling me to allow the app in Health and not. Confirmed all settings on both watch and phone are correct, all items “Allowed” access to each other. Power cycled both Watch and Phone after installing app. Force quit and re-opened both Phone App and Watch App several times. The Cardiogram app is able to pull all static health data from Health App but it is not reading anything at all on my wrist via the Watch App. The App widget is running ion my watch saying it is recording but it will not allow for Pause or Stop so I HAVE to force quit it to get it to stop, and still no recorded datas every displays or shows up as being actually recorded. Save you .99 for now. “Developer” is making money from the people that are not aware that the app with the name that they are looking for is no longer available in the app store and are instead finding this one.

Altered Review

It does work, but I don’t know how accurate, because I have a pacemaker and it seems to fluctuate.

Response from developer

You need to install and run the companion Apple Watch app. Go to the Watch app on your iPhone, scroll down to available apps, find Cardiogram, and click install. Then run the app.

Doesn’t work
