CBG Ed is a structured education platform for minimally invasive gynecologic surgery (MIGS), built for OB/GYN residents, fellows, and practicing gynecologic surgeons who want a single, organized place to study the field. The app follows a two-year curriculum modeled on fellowship-level training. Each module gathers the key readings, questions, and review material for a topic, so you can work through the specialty systematically instead of assembling resources on your own. WHAT'S INSIDE - Curriculum: modules covering the core areas of minimally invasive gynecologic surgery, from preoperative evaluation through advanced laparoscopic and hysteroscopic procedures. - Reading library: curated articles drawn from the peer-reviewed literature and major society guidance, organized by topic. - Question bank: more than 600 board-style questions written at fellowship / ABOG Focused Practice Designation level, each with a detailed explanation and references. - Flashcards: spaced-repetition cards for durable recall of high-yield material. - Videos: selected surgical and didactic videos linked to the curriculum. STUDY TOOLS - Track progress across modules, questions, and flashcards. - Take notes, highlight passages, and bookmark anything for later review. - See your question performance to identify where to focus next. PRACTICAL NOTES - Free to use. - You can explore the entire app without an account. Sign in with Apple, Google, or email only if you'd like your notes and progress saved and synced across devices. - Designed for iPhone. CBG Ed is an educational reference for clinicians and trainees. It is not a substitute for clinical judgment, institutional protocols, or formal medical training, and it does not provide patient-specific medical advice.

Verdict
The clearest difference is rating: CBG Ed at 5.0 against ACR Guidance's 3.1. CBG Ed also leads on update cadence (daily vs every 2 months). ACR Guidance's advantage is ratings volume (12 vs 2) and device support (3 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.
