About this app

Prepry is the ultrasound registry review built so you want to study every day. 100,000+ sonography students have used Prepry to prepare for their ARDMS®, CCI®, and ARRT® registry exams, with a 99.0% reported pass rate among full-access students.

Practice ultrasound physics for the SPI exam, then move on to your specialty: abdomen, OB/GYN, vascular, echo, breast, pediatric, and more. Take timed mock exams, see exactly where you are weak, and drill those areas until your readiness score says you are ready. Missed questions come back on a spaced repetition schedule until you master them. Earn your RDMS®, RVT®, RDCS®, RCS®, or RVS® credential.

Content created by RDMS®, RVT®, and RDCS® educators. Built by an RVT who taught vascular ultrasound.

NEW: ULTRASOUND PROTOCOLS
Ultrasound scanning protocol videos, like the Carotid Artery Doppler exam, plus step by step checklists by body region and normal measurement ranges.

NEW: CHALLENGE MODE
Questions appear without the answer choices, so you recall the answer instead of recognizing it. Not sure? Eliminate the options one at a time, just like on exam day.

NEW: CLINICAL
Track clinicals. Clock in and out, see weekly hours, log each exam in seconds, and follow your skills progress, with protocols and measurement references one tap away.

I have been struggling with abdomen for ultrasound and was starting to feel helpless. Prepry, seems soo much better than the other study guides I have seen. I am a visual learner so prepry was something I wanted to give a try. I enjoy that they have videos, which other study guides lack. This app also has question of the day, quick 10 questions, on top of exams. It is easy to navigate and also can send me reminders /notifications to study. On top of that customer service is quick to respond!

The free 30 questions were more like 10-15 of the same question asked again. If this represents what their full version is like, I believe my preparation for the registry would be severely limited. Not only are the questions redundant, recycled, the explanations are NOT explanations, so you aren't told why something is correct or why other answers would be incorrect. The context is entirely missing from the experience. The user interface is simple and easy to understand.

Thanks for your feedback. Repetition of questions is due to our spaced repetition algorithm, intended for optimal learning. Sorry to hear you found some explanations insufficient. Simpler questions have less in-depth explanations. We value your input and will work on improvements.

I used it to study for my spi. Questions were vastly differently worded. I'm using it now to study for my RVT and questions about box steering seem incorrect. Explanations for answers are vague. I have emailed them with no response yet to my suggestions for edit. Overall it is a relatively decent study source for knowledge but know that the questions on board exams will be much harder and if you have questions explanations may be vague or incorrect
