### 1/5 — Terrible

*2026-05-15*

Explanations are extremely poor. Answers are frequently wrong. When they finally do give an explanation half the time if it’s actually decent it’s almost a page long. The app interface is garbage. The questions stems are terrible as well.

### 2/5 — Decent questions, god awful interface

*2025-05-31*

Lots of questions covering a wide variety of physics topics essential for the core exam. However, some of the answers and explanations are straight up wrong. 
Worst of all however is the absolutely terrible buggy interface of this app. Every time I scroll down on a longer question the options to hit submit and go to the next question disappears and I have to exit out, reload the question set and hit submit. Every single time.

The creator’s last update indicates he’s been too busy to fix the incorrect topics. For how many people us pay for this app to study for the exam, it is his obligation to hire someone to fix it or find the time.

### 3/5 — Not great, but the best we’ve got

*2025-05-30, version 4.3*

The more you use the app, the more you realize it’s riddled with errors, which really degrades your confidence. Several of the questions (out of 500+ total) have no way for you to actually get the answer right. You’ll pick the correct answer, it will be scored as wrong, but the explanation will say that you got it right — and checking with outside trusted references confirms this. Also some of the answer explanations are vague as to which answer was the correct one, the app doesn’t clearly tell you.Formatting in the answer explanations could also be much better, especially when it comes to math formulas. Lots of room for improvement for the developers, if they’re interested in making it better.

### 2/5 — Wrong answers

*2025-05-25*

A lot of wrong answers and typos.

### 3/5 — Needs simple improvement

*2025-05-19*

I know you guys may not be tech savvy but a couple things would make the app more useful: 1. Highlight the right answer. Sometime the explanation may not be straightforward and doesn’t explicitly say what is the right answer ( especially when the wrong choice is chosen). Remember, this app is directed towards radiology residents trying to pass the boards not physicists. 2. The explanation window that pops up covers questions choices. We need to review and contrast choices against each other after knowing the right answer, and this is not possible when that window covers them. Also, it becomes no longer possible to open the image in the question after answering the question. Thanks!

### 1/5 — Glitchy

*2025-05-12*

So glitchy nearly impossible to use wouldn’t buy

### 3/5 — Overall good but infrequent small mistakes

*2024-05-26*

Overall good and very helpful for a resident studying for the Core exam, but there are a few errors that distract from the learning process and means that I can't immediately trust the answers explanations. Some of the errors are simple (wrong answer choice is considered correct, typos that result in no actual correct answer present), but present enough that it is distracting. 

Also, the answer explanation box obscures the answer choices so it becomes hard to see why you may have chosen an incorrect answer and if you were to go back to a previous question in a block, you can't pull up the explanation again.

### 2/5 — Error riddled

*2024-05-23*

Overall a decent app but the amount of mistakes make a confusing topic even harder at times.

### 1/5 — Content good. iPad app bad

*2024-05-18*

Very very bad app design for the iPad. Shame because the content is good. If you are going to buy this, use on your phone. I hope you have a big phone.

### 3/5 — Okayish app

*2024-05-14*

Need correction to few answers. Two correct options has been given in some of the questions & the explanations for some the answers have mistakes.
