What's New in Step Gunner

1.9.8

August 8, 2026

Study by Rotation is here. Pick the clerkship you are on and study every deck it touches in one cross-deck round, or drill a single deck. Nine rotations, Internal Medicine through Psychiatry, each with a live card breakdown and your mastery at a glance. Star your current rotation and it pins to the top and to your Home screen, so your deck is always one tap away. Review my misses is sharper too. Grind your weakest cards with the ones you just missed first, or drill a single Leitner box at a time. Plus a cleaner rotation view, faster review, and polish throughout.

User reviews

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.

Solid Step 2 studying addon

It has been extremely helpful for getting into the framing and focus of step 2 studying. High yield concepts. Have gotten me multiple questions on practice tests. Helpful for those who are not keen on the burden on Anki, but do like spaced repetition as well. Overall pretty great. I definitely recommend

Response from developer

Lowering the anki burden was exactly what I had hoped for. Thank you for validating that.
