Behind-the-scenes cleanup and reliability fixes, including a fix so classmates' score breakdowns load correctly when you tap their name. Optic-chiasm removal (eye path ends at the optic nerve) The new Ocular light-path trace.

Compete and compare with your class: • See how the class did on every question - quizzes and exams will start showing the percentage of classmates who got it right. • Tap anyone on the leaderboard (or the strip atop the IDs page) to see their score breakdown and how long they've been studying. • The leaderboard now shows how everyone's points have moved since your last visit, flags classmates who just joined as NEW, and can give you a heads-up when someone passes you. Better trace practice: • Write-in traces now check your answer automatically - type the step and hit return, just like the quizzes and fill-ins. • New Traces section in Stats & Ranking: see what you've mastered, your step-by-step coverage, and which traces to work on next. • The Traces list shows each trace's length up front and a check on the ones you've mastered. • Fairer mastery - recall every step of a trace in one run and it counts. Smarter, fairer studying: • Smart mode covers more material with less repetition and picks up when you clearly know something (even by how fast you answer). • Traces and fill-ins earn partial credit for what you get right, with a mastery score tuned to the real 219-point practical. • Fill-ins accept Greek letters spelled out (e.g. "alpha-amylase"). • An always-visible search bar, plus fixes and polish. Curated traces • Ensured the app's traces are in compliance with Columbia University policy.

• New: leaderboard notifications when a classmate passes you (on by default, optional in Settings). • Recalibrated the mastery scoring: the flashcards scoring system was a bit inflated, so the scoring system was standardized for everyone and now focuses more on answer accuracy, correct answer streaks, and time intervals between correct answers rather than simple repetition volume. • Quiz Smart mode (focuses your weak/almost-mastered IDs) + Sweep mode for quick overviews; Flashcards "Review All" quick-flip; bite-sized Fill-in Smart Review. • Fixed the IDs search bar/header disappearing, plus trace, MCAT, and layout fixes.

Game Center class leaderboards and achievements are now fixed/live. Plus a couple of study fixes across the fill-ins, traces, and histology exam.

• Class leaderboard & achievements: a friendly Game Center leaderboard (top 10 shown right on the home screen), plus achievements for mastering IDs, traces, and fill-ins. • Mastery Score: one score weighted like the real practical (physical IDs > traces > fill-ins), with bonus points for quizzing and acing full-length exams. Find it under Stats & Ranking. • Smart Review for fill-ins: your weak and overdue questions come first, and each one graduates from multiple choice to write-in as you master it. • Built-in search: now on the home screen, and it searches inside structure notes (function, histology, connections, common confusions) and fill-in questions, not just names. • More and better traces: lipid digestion, GI waste, O₂ mother→fetus, and nitrogen→urine, plus bite-size "Building Blocks" chunks — all in the exact flow-chart format the practical is graded on. • More Real Exam stations from real dissection photos (pinned A–E), new reference diagrams, and more MCAT-tagged fill-ins. • Mac/iPad keyboard shortcuts and smoother navigation throughout.

• Offline mode — download every photo and histology slide to study with no internet. • iCloud sync — your stats, flashcard progress, and decks stay in step across your iPhone, iPad, and Mac. • Traces practice — a new card-based mode with step-by-step images and multiple-choice or write-in recall. • Real Exam, rebuilt — swipeable ID cards, an overhauled set of histology stations, and an "I got it right" self-check. • Quiz difficulty levels — Hard mode serves trickier look-alike options. • Fill-in-the-Blank study mode — multiple-choice or write-in, filterable by topic, with MCAT-relevant tags. • Complete photo coverage — every structure in the atlas now has a real dissection or histology image.

Photo library complete 100%: every structure in the app now has a dissection or histology photo, across all 25 categories!! Also in this update: • Expanded histology detail from the lab handout, including the liver lobule, hepatocytes, and the testis (spermatogenesis) slide • Write-Answer and Real Exam now accept the core name, so "uterus" is correct for the adult maternal uterus • Real Exam stations no longer repeat the same ID, and the intact-kidney station now shows the renal artery and vein

• Flashcards with spaced repetition and custom decks • Stats tab to track your progress • Circulatory System organized into browsable sections for faster navigation • Many more real dissection & histology photos. The majority of structures now have images (~65%) • Expanded content from the lab handout, plus fixes and polish

Launch screen added, iOS 18 compatibility, search results now navigate within results when swiping, swipe hint for new users, structure counter while browsing (e.g. 3/47), category size counts on the IDs page, swipe up/down to dismiss fullscreen images, and minor content fixes.

Real Exam Mode: simulate the actual lab practical with timed stations, gross anatomy IDs, and 37 curated histology scenarios tied to the exact BIOL2501 slide set. Swipe through structures: browse every anatomy structure with a left/right swipe, even across categories — seamlessly. Diagrams view: reference arterial, venous, and digestive system diagrams. Improved answer matching: slash-separated terms (e.g. "Light Source/Illuminator") now accept either component individually. Performance and navigation improvements throughout.
