- Concept checks: short questions on a single concept, mostly in psychiatry, with a few in internal medicine. On paid plans they come up in Practice and Focus, never as the Case of the Day. - Some multiple-choice questions now ask you to choose several options, such as three of eight. Multiple choice is on paid plans. - On paid plans, Practice now leans toward the topics and kinds of question where you are weaker or have not been tested yet. When there is a second question on a concept you missed, Practice may ask it on a later day. - New knowledge map topics: seven in psychiatry, such as neuroscience and genetics, and one in internal medicine for ethics, safety and clinical epidemiology. Each appears once it has questions. - After a concept check, the feedback can show whether most residents get it right or miss it. - On the plans screen, you can now switch from monthly to annual billing, or subscribe during a free month from your program. - When you upgrade, start annual billing, or go from a free month or free trial to paid, your monthly count of graded answers resets to 0. - Fixed the password field's placeholder, which had its letters spread far apart.

Feedback headings now match your score: "What went wrong" when a lot was missed, "What you missed" for the gaps, and "To go further" when you got it all. Reinforce cards show the fix first, and the comparison curve marks the score of the answer on that card. Clearer topic names on the knowledge map, and lab values no longer wrap away from their units.

Your progress now holds up better when you sign out and back in, reinstall, or use a second device, and your streak stays intact. Opening the app offline no longer signs you out. If a grade can't run, you see why, and an answer you were typing isn't lost if the app closes. Grading is faster. The plans screen shows the plan you're on, shares link to Titrate on the App Store, and a lot of wording is plainer.
