A fresh look, and today first. - Today first: your round, your readiness range and your test date in one card at the top of Home. - A new question screen: cleaner cards, the topic shown after you answer, and the why right under your answer. - New moments in a round: bonus XP when you get a question most students miss, and a nod when you fix one you missed before. - Leagues reimagined: see the XP to pass the student above you and to reach the next tier. - Share: send a friend a hard question you got right, or your invite link, from the new top bar. - PRO: Pro members get a gold tag that shines when you open the app. Not on Pro yet? Tap PRO to see what's included. - Refreshed everywhere: Results, Readiness, Profile, Settings, Search, Visual Dx and LFX, in dark and Dawn. - Fixes and polish.

User reviews

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.
