PlasticOS

PlasticOS brings procedure reference, guided practice and daily review into one study app for plastic surgery trainees. FIND THE REFERENCE YOU NEED Consult searches the bundled procedure atlas and returns matching passages with citations. Use it to revisit anatomy, preparation, procedure steps and reported outcomes while studying. Results come from the reference library; they are not advice for an individual patient. STUDY, PRACTISE, REVIEW Explore a curriculum organised from PGY-1 to PGY-6. Follow guided simulations, work through case studies and revisit questions with spaced repetition. Review sessions save your progress on this device, so you can return to your learning routine. CORE CONTENT OFFLINE Study the included reference material without an account or an internet connection. Purchases, restoration and updates need connectivity. Paid access may also require periodic App Store verification. Learning progress is stored on this device and does not sync between devices. The interface is available in English, Turkish and Spanish. Reference content is primarily in English. CHOOSE THE ACCESS YOU NEED Free: foundational topics, basic simulations and spaced repetition review, with no time limit. Resident: Resident-level curriculum topics, core procedure simulations and deeper study resources. Fellow: the full curriculum and all simulations, including advanced procedures, plus decision algorithms and layered anatomy for study. Lifetime: all Fellow features through a one-time purchase. Prices and any available trial are shown before purchase. Trial eligibility is determined by the App Store. EDUCATIONAL USE PlasticOS is a study aid for surgical trainees, not a clinical decision tool. Do not use it to guide care for a real patient. Refer to the cited sources, current clinical guidance and qualified supervision. SUBSCRIPTIONS Resident and Fellow are available as monthly or yearly auto-renewable subscriptions. Payment is charged to your Apple Account at purchase confirmation. Subscriptions renew automatically unless cancelled at least 24 hours before the current period ends.

Verdict
The clearest difference is in-app purchases: OpNotes at none against PlasticOS's 5. PlasticOS's advantage is update cadence (weekly vs every 2 months). On price, ads, device support and iOS requirement there is nothing between them.
