PlasticOS is the plastic surgery residency curriculum as an atlas you can search, a question bank that shows what you really know, and a voice that reads it to you. LISTEN All 146 board-level topics can be read aloud by your iPhone's own voice: hours of review for the commute or the call room. A caption follows the sentence; change the speed, skip, and pick up where you stopped, even with the screen locked. 86 procedures, the way a senior takes you through them: the anatomy to know before you scrub, assessment, every operative step with its pearls and hazards, donor site care, monitoring and outcomes, each with its primary reference. CONSULT Ask a clinical question and Consult searches the atlas and the topics as you type: "venous congestion in a free flap", "when is a DIEP contraindicated". It returns matching passages, each with its citation. It writes nothing itself and declines questions about a specific patient. You can also ask in Turkish or Spanish: the medical terms are matched to the English atlas on your device, and the screen shows the English query it searched. Measured before every release on more than a hundred clinical questions in each of the three languages. THE CURRICULUM: 146 TOPICS, ALL AT BOARD LEVEL PGY-1 to PGY-6: wound healing and grafts, local flaps, craniofacial and cleft, hand and nerve, breast, trunk and lower extremity, burns, microsurgery and aesthetic surgery. Every topic is written at board level, from skin grafts and burn resuscitation to cleft surgery, cranial vault remodeling, flexor tendons, wrist arthroscopy, DIEP flaps, lymphedema surgery and melanoma. Each has key numbers, classifications, algorithms, flashcards and references with PubMed IDs. QUESTION BANK: 2207 QUESTIONS Single-best-answer questions, mostly clinical vignettes, with the reasoning for every option, shuffled on each attempt. A mock exam is timed and weighted by exam section, with a review of every answer. Review and flashcards are scheduled with FSRS, a modern spaced-repetition algorithm. Explain it back: write a topic from memory, then check it against its key points. Progress shows mastery by exam section and what is due. TOOLS Figures drawn by the app, step by step, that can also play with narration: Z-plasty and local flaps, graft and burn depth, tendon zones. Teaching calculators that show their formula and source: Z-plasty gain, burn TBSA (Lund-Browder) and fluids, local anaesthetic maximum dose, Caprini. OFFLINE AND PRIVATE Everything ships inside the app, including the voice. No account, no analytics, no server of ours. Your progress stays on your device and does not sync between devices. PLANS Free: PGY-1 fundamentals, three core procedure walkthroughs, spaced repetition, emergency protocols and decision pathways, permanently. Resident: resident-level topics and the core procedure walkthroughs. Fellow: everything in Resident plus fellow-level topics and every walkthrough, including advanced microsurgery. Lifetime: a one-time purchase of everything in Fellow, including future updates. Resident and Fellow include a 7-day free trial. Residency programmes can license seats by invoice. WHAT THIS IS NOT A study aid for surgical trainees, not a clinical decision tool. The calculators are for teaching; nothing in the app should guide the care of a real patient. Built by a plastic surgeon. SUBSCRIPTION AND LEGAL Resident and Fellow are auto-renewable subscriptions, monthly (1 month) or yearly (1 year), each with a 7-day free trial. Lifetime is a one-time purchase, not a subscription. Payment is charged to your Apple Account at confirmation of purchase. A subscription renews automatically unless auto-renew is turned off at least 24 hours before the end of the current period. Manage or cancel it in your Apple Account settings.

About

OpData

Features
Read full description

OpData-Drive is a logbook for doctors who operate or perform procedures. After each case you fill in a short form on your phone. The app keeps all your cases in one place, counts them for you and can write them to a spreadsheet in your own Google Drive. HOW IT WORKS 1. Sign in with Apple or Google, then choose your specialty and title. 2. After a case, tap New Operation and fill in the form: patient initials, age, sex, diagnosis, procedure and the details your specialty needs. 3. Your home screen, calendar and statistics update at once. Your logbook is ready whenever you need it for training records, a CV or an academic application. FORMS FOR 19 SPECIALTIES Neurosurgery, General Surgery, Orthopedics and Traumatology, Cardiovascular Surgery, Thoracic Surgery, Pediatric Surgery, Plastic Surgery, Urology, Ophthalmology, Obstetrics and Gynecology, Oral and Maxillofacial Surgery, Otorhinolaryngology, Emergency Medicine, Interventional Radiology, Anesthesiology, Internal Medicine, Cardiology, Dentistry and Pediatrics. Each form speaks the language of its specialty: target structure, classification, procedure type, implant and graft options change with your specialty. You can hide the fields you do not use. WORKS WITHOUT INTERNET Enter cases in the operating room without a signal. They sync in the background when you are back online. YOUR NUMBERS AT A GLANCE (PREMIUM) Today, this week, this month and this year; a calendar of every case; your most frequent diagnoses and procedures. Ask the ODD Statistics Assistant a question in plain words, such as "How many cases did I log this month?" YOUR OWN GOOGLE SHEET (PREMIUM) Link your Google account and every case is written to a spreadsheet in your own Google Drive. The sheet belongs to you: download it, share it or analyze it any time. TEAM (PREMIUM) Add the colleagues who scrubbed in as team members of the case. The record also appears in their logbook. PRIVACY AND SECURITY No patient names are collected. Only initials can be entered, and the field enforces this. Records on your device are encrypted with SQLCipher and every transfer to the server uses TLS. No ads, no analytics, no tracking. FREE AND PREMIUM Logging cases is free, and the free logbook shows your last 7 days. Premium adds statistics, the assistant, your Google Sheet, team sharing and your full history. Monthly and annual subscriptions are available. A 7-day free trial starts when you link your Google account. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the period; manage or cancel them in your App Store account settings. IMPORTANT OpData-Drive is not a medical device and does not diagnose, treat, cure or prevent any medical condition. It is a logbook that lets healthcare professionals keep their own case records. You are responsible for following your institution's privacy rules and the applicable regulations when you enter patient data.
