【From the Developer】
I started this app to build an ECG question bank with as many questions as possible. Creating 1,100+ questions was demanding, but each was made for people who want to learn—and love—ECGs. Explanations emphasize a reproducible interpretation process.
The app continues to evolve into a platform for learning, exam prep, skill assessment, and competition. I hope it supports your learning and clinical practice.
