As soon as I click on the the main bundle option the app shuts down. I would be very happy to receive some help with this issue. **Developer response:** We are sorry to hear that you've been experiencing issues with our app. Could you please uninstall QEVLAR Radiology and then install it again? If the error persists, please contact us directly at contact@imaios.com and let us know which bundle is involved. IMAIOS SAS ### 1/5 — Do not use for nuclear medicine *2022-01-09* Used QEVLAR for ABR general exam prep and thought it was fine. Purchased both NM banks for subspecialty NM exam and was disappointed. Majority of questions have poor phrasing making it hard to identify the teaching point, out of date answers or are “read my mind” questions with multiple valid answers and no explanation for why the author thought one answer was best. Not convinced questions were proofread. Explanations are sparse and do not cover why distractor choices are wrong. **Developer response:** Thanks for your feedback! We appreciate your suggestions and will keep them in mind for the future update. If you have further questions please contact us at contact@imaios.com. ### 1/5 — Terrible *2021-11-27* Asks for login without the option to subscribe. Does not come with any of the said bundles except a small 25 questions demo. Just ridiculous. Dont waste your time. **Developer response:** Sorry to hear that you are experiencing issues with our app. In fact, you need to create an IMAIOS account on the web and subscribe there. Please visit https://www.imaios.com/en/QEVLAR-app-for-Core-Exam-prep to find out about our bundles and subscribe. QEVLAR app is a companion to use those bundles on your mobile.

IMAIOS SAS ### 1/5 — App doesn’t support google account *2021-03-11, version 2.1.0* I register using my google account on the web version. But unfortunately the app does not support that 🤷🏽‍♂️ i contact customer surface and they said that i have to click on “forgot your password” but this button is not working as well. **Developer response:** Dear Mhmsalem, we are sorry to hear you can't login properly. As we said if the "forgot password" is not working on the app, you might want to try directly the Forgot password button on our website. We are still investigating the issue on the app. Best regards, The IMAIOS Team ### 1/5 — App keeps shutting down *2021-02-03* App keeps shutting down **Developer response:** We are sorry to hear that you are experiencing issues with our app. Could you please send an email to contact@imaios.com, so that we'll try to help you the best we can. Marina ### 1/5 — This app is broken *2021-01-06* Can’t do quizzes on exam mode. Shows answer each time. **Developer response:** We discovered this bug appears only when using the "exam" preset, please use the "Show answers after each question" button directly and it should work as expected while we fix the issue. The IMAIOS Team ### 1/5 — Over priced for what you get *2020-11-28* Pricing is way too high for this severely limited app. UI is terrible, constant errors and crashes all the time. Web interface isn’t any better. Very much a half baked solution. Most questions are ok though. **Developer response:** Dear JFloyd25, We are really upset that you are dissatisfied with the app. Dont hesitate to contact us at contact@imaios.com to tell us more about your issues and we will help you the best we can. Michael, IMAIOS team ### 1/5 — Sync *2018-05-19* So it seems like people have been complaining for 2 years about the app not synching and still nothing's been done...that's frustrating ### 2/5 — Sync does not work *2016-11-26* Cannot go between platforms, synchronization does nothing - extremely inconvenient. ### 2/5 — Doesn't sync *2016-04-25* Studying for the radiology core exam and very disappointed with the app. While the interface is decent, it never successfully syncs to the main server. Therefore if you switch between using the app and web based browser, there will be a discrepancy in which questions you have already completed since the two systems are not able to communicate with each other. If this issue can be fixed, the app would be much better. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
