What's New in Step Gunner

2.1.1

August 24, 2026

Your projection now shows its track record. Under the readiness gauge you can see how the last ten students who sat Step 2 actually landed against the range the model gave them, miss by miss, including the ones we got wrong. Scores come from students in the app and from r/step2 score reports the model never trained on. It updates every week as more scores come in. A prediction you cannot check is just a guess; this one you can. Also in this update: - Every five-option CK Gold question now explains why each wrong answer is wrong, not just four of them. Nearly a thousand cards updated from a single report - Dozens of card repairs straight from your reports: clearer age ranges, corrected keys, cleaner stems. Reports pay XP, keep them coming - Notifications about your readiness now open straight to the gauge - Groundwork for a faster first look at where you stand after your first round

Loved the NBS part

The next best step has been my weakest area and I love how they have such a short questions and the answers include the whole algorithm of treatment . Love it

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.

Response from developer

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!

Response from developer

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.

Response from developer

I appreciate the feedback! Working on adding more content. Most likely within 7 days.
