With MDCalc apps on my phone, there's no reason I'd use any other source (doesn't matter if it's yours or another) because MDCalc is credible and reliable (why take a chance on a calculation error on other sites). Furthermore, what a clerk is "expected to know" varies wildly by hospital, preceptor, and your own goals and having gone through clerkships/SubI myself, there are many things missing.
I think graphics look nice, and while there are other resources that already exist, guides on how to survive clerkships are a valuable resource for students. I just don't think there's any point in redoing all these calculators (note: anything "actually" medical).
