This app is extremely helpful to medical students who are on their ObGyn clinical rotations and/or studying for shelf exams. Before starting my ObGyn clerkship, I reviewed FHR tracings using this app and felt incredibly prepared to look at real tracings in the clinic and on Labor and Delivery. A year later, before starting my Sub-internship ObGyn rotation, I again used this app to refresh my memory. Within 10 minutes of looking through the app, I could again recall the most high-yield info that students need to know. It’s very easy to use and provides a quick, interactive review of reading FHR tracings.
