Many correct answers are marked as wrong, which is frustrating. And there is no way to report such errors.

I own all of your apps and also i pay for the in app pucharse, but i have another divices but i cant have my progress of other divices. please can you make something like add Croos-divice synchronization? we all pay for your content, please help us

The update deleted all of my progress as well. Additionally the new GUI is atrocious and not nearly as user friendly. Please revert to the old GUI.

App updated itself and deleted all my PURCHASED questions as well as analytics. Awaiting gwhiz resolution. Terrible interruption of otherwise smooth test prep.

If your device is synced with the same iTunes account as the original purchase - follow the same steps to buy the upgrade. Once you confirm, you'll get a popup that you already own it and you won't be charged again.

I already bought the questions for my iPad. I shouldn't have to buy them again for my iPhone.

I recently had the misfortune of having my ipad fail and was forced to buy a new one. Lo and behold, my purchase of the other 900 questions - along with my $45 investment - disappeared along with my previous ipad. Thanks for nothing.

It works for practicing the questions but there are some glitches like others have mentioned. There isn't any way to only answer the only questions that you haven't seen yet. So, you'll finish a set it will say you haven't completed 3 or 4 but then when you try to go back, there is no way of just going through those. (Either that or it doesn't count them/have them to answer.) Also, I have come across questions where the response set or the explanation has been swapped between questions. I was able to download to other devices, but it looks like it will make you pay for it. I held my breath and hit ok and then it popped up with a message that said I had already purchased it and downloaded it without charging. That said, it doesn't communicate between the two which question you have already completed so I have ended up just using my phone.

Excellent product. And to all those saying it won't transfer over, you guys try again. Once purchased it will transfer to ipad or iphone. Questions are 2 steps and in some cases 3 steps even. A good balance to further your knowledge for sure, since its disecting First Aid USMLE book. I would recommend it.

No lab value option; only two free questions per section. Questions are far below the level of UWorld. Might as well do the free version, but don't have high expectations and don't buy the full version.
