No Content – USMLE Step 1 Smartcards and tests Review

I tried the app both on Iphone 7 and Ipad and it does not allow you to sign up, no content is showing except for the tutorial. No ability to contact the developer as well. I wish they see this comment and fix the issues with the app and their website.
