## Most critical reviews (9 lowest-rated)

### 1/5 — Doesn’t work, don’t waste your money

*2026-06-04*

This app doesn’t work.

### 1/5 — Ne fonctionne pas correctement sur Apple Watch 7

*2026-05-19*

Malgré l’installation, l’application ne fonctionne pas correctement sur mon Apple Watch Series 7

### 1/5 — Doesn’t work

*2026-05-07*

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

### 1/5 — IPhone 17 Pro Max - Does not work

*2026-04-13*

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.

### 1/5 — App changed name and now got more problems

*2026-03-30*

somehow there are problems with receiving data from the watch. it always shows 0 but it does its meassures which can be seen in heartratemonitor app. please fix it

### 1/5 — Doesn’t work

*2026-03-21*

It’s a blank page with a picture of a heart.  No way to sync with Apple Watch   Don’t waste your time with this app

### 1/5 — No AirPods support

*2026-03-04*

You might think adding AirPods pro 3 heart monitoring was mandatory for an app like this, but apparently it is not.

**Developer response:** For now, AirPods do not provide any health data unfortunately.

### 1/5 — No app

*2026-03-04*

I downloaded what I thought would be an app. There is none. The page is almost blank with a picture of a heart. It does nothing and no way to contact the developer.

**Developer response:** 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.

### 3/5 — Altered Review

*2026-03-30*

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

**Developer response:** 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.
