### 1/5 — Got charged for renewal

*2021-11-03*

Never signed up for renewal and got charged for it. Shady in-app purchase tactics.

### 1/5 — Unable to unlock purchased app

*2020-11-14*

I have purchased the 1yr subscription but only the free trial opens. Very very frustrating

**Developer response:** Sorry to see you’re having trouble with this app! Please reach out to our Customer Success Team at support@hltcorp.com or 319-246-5271 for immediate assistance.

### 1/5 — Very Dishonest and Frustrating App company

*2020-01-31*

I had purchased full amount of several HLT apps, just because I like to learn from different sources, Just seeing Usmle step 1 app ( paid full amount price) just not opening, crushing and I am gonna go after my rights, My lawyer friend already created a case toward it. 
If You cannot promise Your word, why taken my money away in a trade of total frustrations? 
Another apps of the company started subscription based charges, so my account is not opening in my own paid apps of this company.... What the heck I have to deal with this crappy apps of HLT?

### 5/5 — Great App

*2018-05-26*

In depth amount of questions from each subject to be covered on step1, in depth detailed explanation on why a certain question was right or wrong, great study tool

### 5/5 — Great Question Feedback

*2018-04-29*

I really like the detailed feedback given for each question.

### 3/5 — Too Easy - False Sense of Mastery

*2017-08-25*

Gives you false sense of material mastery. The answer are often the most popular disease. I'm an undergrad and am hitting 50% pass by picking the answer (out of 4 choices) that "sounds" like the related diseases based on the name or picking the disease I know is related. 

The last question I under answered  (physiology/ nervous system section) that prompted me to write this review: 

Q: Which is part of somatic system?
A: answer choices included skeletal, glands, smooth muscle (things like that)

It'd be different if that section had hundreds of questions with an occasional high school level question like this, but it only has 40 for the whole subcategory. That's not good use of study time....

Social sciences example:
Drunk patient comes into ER. Do you expect sedation, dilated pupils, bradycardia, or tachypnea?

Obviously sedation. If you throw in a "sure answer" everyone's gonna pick it and the person studying never gets to solidify knowledge and realize what he doesn't know. I imagine an actual USMLE question would gives choices like tachypnea, tachycardia, bradycardia, or dilated pupils. 

THAT would make you actually have to think between the choices and test what you really know and alert you to deficiencies of you got it wrong on the app! 

Of course there are harder questions, too, from my undergrad perspective . But it makes me wonder if those would be considered easy also by an actual med student...

It does cover a good breadth of material though and gives nice explanations. Very convenient to use while waiting in line, on the us, etc.

**Developer response:** Hi there! Thank you for your honest review, we really appreciate it! I will make sure our Medical Subject Matter Experts see this. If you want to reach out to us with any other feedback, we would love to hear from you! You can reach us at feedback@hltcorp.com

### 5/5 — Easy access to practice!

*2017-07-15*

A friend told me about this app and I'm so glad he did! I'm using the USMLE First Aid book too, but that thing is a brick to carry around. This way I have practice readily available. When I'm waking up and wanna stay in the blankets a bit longer, at long traffic lights, in line, wherever! I feel like I can always learn something.
The explanations are to the point and clarifying. They've even got the ability to improve a question with a quick email link that puts the question and everything in there for you. I haven't had to use it yet, but awesome feature!
I also really like being able to rate my answers "don't know", "somewhat know", or "know". And then be able to review the question in each category separately or all together. Helps me really hone in on the things I need to be reminded of.
Pricy, but no worse than any other worthwhile study tool for boards.

### 1/5 — Low quality questions

*2017-04-29, version 4.2.4*

Poor quality with incorrect info.

### 5/5 — Great app

*2017-04-18, version 4.2.4*

Awesome.. this is one of the best USMLE step 1 Q bank that I've ever seen before.. 100% recommended

### 5/5 — Awesome !!

*2017-03-10, version 3.24.2*

Its too good .... beautifully explained answers 👌 concept clearing app 👍
