What's New in Step Gunner

2.4

October 30, 2026

Your readiness, turned into a plan. - Today's plan: the Readiness tab opens on what to study today, built from your weakest systems and what Step 2 tests most. The first drill is free every day. - Drill 10: one tap drills 10 cards in a weak system, missed cards first, from Readiness, Home, Profile and the topic breakdown. - Calculator search: type HEART score, CURB-65, anion gap or any of 31 bedside calculators into search and it opens in its ED pathway, ready to run. - An honest number: no projected score until you've answered 50 questions or logged an NBME, a failing NBME no longer reads as passing, practice tests stop counting after 8 weeks, and the range says how sure it is. - After your exam: Readiness shows your real Step 2 score, or asks how it went. Took it early? Set the day, and your score is matched to it. - Pro in one step: sign in with Apple right inside the purchase. - A calmer background behind every screen. - Fixed: Profile and the daily reminder now count CK Gold, and Practice again after a CK Gold topic drill serves CK Gold.

Response from developer

Amazing!! Thank you for sharing your experience with the NBS section. NBS was one of the areas I struggled with most, and I built this hoping to make it a little easier for the next generation of medical students. I’m so glad you found it helpful. I really appreciate the feedback!!

Good for extra

I always run into a problem where I use all my UWorld early and finish my anki cards in my free time. This is super nice for when I am standing around on rotations with no responsibilities, but can’t access my computer to study.

Nice!!

Fantastic

Is there a way to review everything in one place?

Response from developer

Just improved the rapid review section to review everything at once and submitted it to the App Store. You should see that button pop up on the Home Screen once it gets approved.

Best app ever!!

Best app ever!! Makes me learn the next steps in management of so many high yield presentations in such an efficient manner! So grateful to find an app that is free, easy to use and also use to ensure a laid back learning experience! I am so so grateful to the med student who created this app!

Thank you!! I’m glad you’re enjoying it.

Need more cards please

Content is really good as of now and however you may wish, it feels illegal to have all this without any paywall. I would have happily paid for this. Can you please add more cards related to NBMEs and CMS. It will be really helpful for us. Also I don’t mind paying for that if you desire to add it as a premium feature. But need more content real soon as exam is near.
