Would you mind reaching out to us directly at support@hltcorp.com? We typically respond very quickly. ### 1/5 — Automatically charges you after 3 days! *2018-12-07* Rip off! **Developer response:** Hey there, we are extremely sorry about your frustrations and would absolutely love to help. Reach out to us at nursing@hltcorp.com we would love to speak with you! :) ### 2/5 — No practice questions? *2018-07-06* I downloaded this and it advertises *145 practice questions with explanations* and I cannot seem to access them through the app. Oh well. **Developer response:** We would love to help resolve this for you, reach out to us at nursing@hltcorp.com :) ### 1/5 — Terrible. Don't waste your time or money *2017-11-12* Twenty bucks for a brief description of each arrhythmia with no way to quiz yourself. What am I paying for? **Developer response:** Thank you for the feedback, we appreciate it! We would love to discuss this with you further. Would you mind reaching out to us directly at support@hltcorp.com? We typically respond very quickly. ### 1/5 — That's it? *2017-08-13* Thank Christ they give you a trial for the premium membership. The app is completely lackluster. It gives good explanations on some typical EKGs but with very few examples. It overlooks others such as Brugada syndrome. Absolutely the biggest problem with the app is the lack of quizzes. There are no options to test yourself on random 12 lead EKGs and at $20, you'd expect thousands of examples. Needs a hell of a lot of work or needs to be completely free. ### 1/5 — Too expensive for $20 *2017-08-09* Well, I am expecting an organized well presented ECG with corresponding interpretation and treatment. It looks like a lectured type in a MS Word style. It's not worth of your $20. Unfortunately, I just purchased it after seeing a well presented layout with causes, s/sx for each for free. I want a refund. **Developer response:** Thanks for your honest feedback! We would love to discuss this further with you. You can contact us directly at feedback@hltcorp.com. We look forward to hearing from you! ### 1/5 — Don't purchase this app *2016-08-28, version 3.18.5* I was under the impression this app would help/teach me read ekg strips. It does not explain it. This app is too basic. I hope I get my $20 back. ### 1/5 — Nothing special *2016-08-25, version 3.18.5* Just the basics with different types of ecg's. I was hoping for something much more for 20$ (on sale). Very disappointed and am going to try to get my money back. ## Most critical reviews (10 lowest-rated) ### 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. If that doesn't work, please let us help you resolve this problem. Get in touch with us at support@hltcorp.com or 319-237-7162 whenever it is convenient for you. We would love to hear from you! ### 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. **Developer response:** Hi, this is Sarah from ECG EKG Interpretation Mastery's Customer Support team. Thank you for leaving this review and for your honesty. I'm sorry you haven't enjoyed the app. We are continuously working on adding more features to improve your experience. If you have suggestions, please get in touch with us at support@hltcorp.com or 319-237-7162 whenever convenient.  We would love to hear from you! ### 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. ### 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. ### 1/5 — Terrible app. Money sucker *2019-08-08* All the info can be EASILY found online for free and you will be better off as the app is very vague, nothing in depth. $9.99/month what a joke. **Developer response:** Thank you for the feedback, we appreciate it! We would love to discuss this with you further. Would you mind reaching out to us directly at support@hltcorp.com? We typically respond very quickly. ### 1/5 — You’ll end up paying *2019-07-25* Not free. It’s one of “agree to pay if you fail to cancel in 3 days” gimmicks. No time for that. **Developer response:** Sorry for the confusion. Unfortunately, that is the only way Apple presents us to offer free content and then have subscriptions available for the larger product. Please contact us if you're having any issues: Support@hltcorp.com ## Most praised reviews (10 highest-rated) ### 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! **Developer response:** Hi, this is Sarah from ECG EKG Interpretation Mastery's Customer Support team. Thank you for your feedback. We are continuously working on adding more features to improve your experience.

We're thrilled to hear you are enjoying the app :) If there's anything we can do to enhance your experience, please do not hesitate to let us know! Thanks again! ### 5/5 — Need improvements *2018-05-30, version 5.11.1* No daily task clearly No daily questions ### 5/5 — ECG/EKG MASTER *2017-06-02, version 4.3.2* Just enjoying and keeping up my skills in exploring understanding deeper 😜 ### 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. ### 4/5 — for iphone x *2018-04-02, version 5.8.8* the screen is not yet compatible with iphoneX ### 4/5 — Great App *2016-09-23* Just took an EKG class online & this app is basically everything I got out of the class. Previous reviews stated it didn't teach u, but everything is there you'll need 2 know. Just gotta read it... ### 3/5 — Can't use *2017-04-26* Can't even use the app without giving your email address or using Facebook. That's a shame. **Developer response:** Hello! Thanks so much for your review. We apologize for any inconvenience. The purpose of the "Log In" function is actually to allow you to sync your progress across multiple devices. We would love to talk more about this with you in detail! Please reach out to us at feedback@hltcorp.com. Thanks! ### 2/5 — Emt *2019-03-05* Great except having to upgrade so soon. **Developer response:** Thank you for the feedback; we appreciate it! We would love to discuss this with you further. Would you mind reaching out to us directly at support@hltcorp.com? We typically respond very quickly. ### 2/5 — Hmm *2018-12-13* Where are the questions? **Developer response:** Thanks for taking the time to tell us about your experience! The app store description and screenshots explain that this is an app to assist with EKG interpretation, not a question and answer experience.
