### 1/5 — Not useful

*2025-01-25*

Don’t waste your time with this. It’s not user friendly and there are very few examples of anything. And the “quiz” is impossible to use

**Developer response:** Hi, this is Sarah from ECG Mastery's Customer Support team. I'm glad you reached out to us through this review. Small app download errors can sometimes cause an issue like this. In many cases, clearing the app from the device and reinstalling it can resolve this issue.

### 5/5 — Wow

*2024-08-19*

Simple format, easy to understand, nice graphics. A lot better than the black and white book I got in tele class!

We are continuously working on adding more features to improve your experience.

### 1/5 — Complete waste of money

*2024-07-31*

Always good if there’s a free trial available so that you can see for yourself. 
This is THE worst app. I am shocked that anyone would actually pay money for it. Actually I don’t believe anyone does and if they do? They definitely do not use it. Because there’s nothing to use!!! It’s shocking how lame.

### 1/5 — Just note cards

*2023-11-09*

There’s no actual lessons. Only about 20 note cards .. that you could easily just google on your own. To pay $12 a month for 20 note cards is kinda outrageous … I wanted actual lessons as I already have notes from my education.

### 1/5 — Terrible

*2022-12-26*

Worst ekg app ever and wayy to expensive. Doesn’t do anything that it describes

### 1/5 — Mostly useless

*2022-01-22*

Mostly useless unless you are looking for basic information. It requires a paywall to access anything beyond the basics

### 1/5 — Took 33$

*2021-02-28*

Signed up for 3 day trial was instantly charged 33 dollars.

**Developer response:** If you have not, please reach out to us at nursing@hltcorp.com We never want this to happen!

### 1/5 — Expensive, and huge invasion of privacy

*2020-07-03*

First the cost. This app offers a three day free trial, then it is 12.99 per month after that. If the app is good, I’m ok with paying that much money. 

But I’m not ok with the privacy policy, which is outrageous.  The privacy policy says that this app may collect my contact info, my contacts/address book contents, and my photos and social media accounts. Seriously???   Stop and think about that. Why would I give this company my address book? Why would I give them my personal photos or social media account details? What the heck???

And it gets worse. They plan to get information about me from other sources, and combine that with their profile of me. This so that they can share my details with marketers. They may also share my information with friends who are associated with my social media account.

So that is the real price of using this app. It’s not just the 12.99 charge each month - it is that the user has to give up privacy, and also give up the privacy of friends who are in the user’s address book. SHEESH.

That is crazy, so I am deleting this app.

### 4/5 — Great but expensive

*2019-09-09*

I like it a lot - it’s like a reference book on my phone. Problem is it’s also quite a bit more expensive than a reference book because you have to keep paying for it monthly. If it were one flat fee I’d say it was worth it but being charged constantly for the same resource is not worth it. I’d recommend a book instead.

**Developer response:** This is great feedback - will pass this on to the team here.We are glad you find the content and convenience useful.

### 1/5 — You actually have to pay for it

*2019-08-28*

You sign up, go to start, and everything is locked. You have to pay for it.

**Developer response:** We appreciate your feedback. We do offer enough free content to evaluate the content, and we do need to charge for the service in order to support the talented staff of nurses, editors, and writers who create the content. We'd love to hear from you how we can make it more appealing! Drop us a line at Support@hltcorp.com.
