Review momentum
71/100
faster than 81% of Medical apps
Review momentum (0-100) blends how fast the app collects ratings compared with other apps in its category (60%), whether that pace is speeding up (25%) and what recent raters give it (15%; recent stars well below lifetime pull it down). Ratings counts are read daily. A jump usually means a launch, a feature, ads or a new review prompt.
About ECG Trainer: Monitor & 12-Lead
Make learning ECGs more enjoyable—and easier to continue.
This is a new kind of ECG learning app that lets you build your skills through game-like practice.
Monitor ECG Mode includes a wide range of important waveforms commonly encountered in clinical practice, including normal sinus rhythm, PACs, PVCs, atrial fibrillation, AV block, ST elevation, and life-threatening arrhythmias such as VF and VT.
By watching monitor waveforms move in real time, you can intuitively learn their key features and understand how to tell them apart.
In 12-Lead ECG Mode, you can also learn to identify abnormal findings quickly and enjoyably through game-like exercises.
Go beyond simple memorization and build knowledge while having fun.
Naturally improve your ability to recognize waveforms, make faster decisions, and develop practical skills that can be used in clinical settings.
Key Features
・Learn Through Play
Study ECGs without getting bored through quizzes and challenges.
The experience is designed to make you want to keep going, rather than making learning feel like a chore.
・A Sense of Achievement Through High Scores
Earn points based on the number of correct answers and how quickly you respond.
The more often you challenge yourself, the more clearly you can see your progress.
・Global Leaderboards
Compete for high scores with users from around the world.
Enjoy learning, stay motivated, and make it easier to continue practicing.
・A Wide Range of ECG Waveforms
Learn everything from basic normal waveforms to clinically important arrhythmias and abnormal findings.
The app is useful both for those who find monitor ECGs difficult and for those who already have some ECG knowledge.
・Useful for Both Study and Clinical Practice
Ideal for nurses, doctors in training, medical students, and anyone studying emergency medicine or cardiology.
It is also useful for short study sessions, repeated practice, and exam preparation.
Whether you find ECGs difficult or already enjoy studying them, this app is for you.
Turn “difficult” into “understandable,”
and turn “understandable” into “enjoyable.”
