## What is ECG Trainer?

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.”

### 4/5 — いい勉強になります。

*2026-07-03*

心電図の復習に役に立っています。

### 5/5 — 最高！！！！

*2026-06-18*

僕は将来「フライトドクター」を目指しています。
その中で1番得意になりたいのが、「心電図波形」です。
アプリで色々調べてみたけれど...
1番楽しくて分かりやすく出来るのはこのアプリです！！
波形の種類も他アプリに比べると豊富で、課金をするだけでもっともっと分かりやすくなりました！！！！

**Developer response:** レビュー、高評価頂きありがとうございます！とても励みになります。今後も楽しく学んで頂けるようアップデートを行なって参りますので引き続きよろしくお願い致します。

### 2/5 — App Erased my Progress and No Longer Works at All

*2026-06-04*

I paid for the full version of the app so I could train for my new position as a monitor tech with no ads. I had progressed and unlocked all challenge difficulty levels, and I made my own custom tests as well. Now the app erased all my progress and crashes every time I try to start a challenge. It was a good app when it worked, but now my money is wasted.

**Developer response:** We are truly sorry for the inconvenience and frustration this caused, especially after you paid for the full version of the app.

The issue where Challenge Mode could crash or fail to start has now been fixed, and the app should be working normally again.

Regarding the lost progress: in the previous version, if the app was deleted and then reinstalled, locally saved data such as scores, unlocked challenge levels, and custom tests could be removed from the device. We sincerely apologize that we did not have enough protection in place for that situation.

In the next update, we will add a backup feature so that, even if the app is deleted and reinstalled, scores, unlocked levels, and custom tests can be restored as much as possible.

We take your feedback very seriously and will continue improving the app so it can be a more reliable tool for learning and training. We are very sorry again for the trouble this caused.

### 1/5 — ERROR

*2026-06-02*

It keeps giving me 5/6, but does not give me all 6 questions. And it does not give me an option to report this error. So I have to do it here.

**Developer response:** Thank you for reporting this, and I’m sorry for the inconvenience. I found the issue where the quiz could stop at 5/6 instead of showing all 6 questions, and I’m fixing it now. I’ll also review the in-app error reporting flow so problems like this can be reported more easily in the future. Thank you for taking the time to let me know here.

### 5/5 — cool app

*2026-01-11*

great app but too many ads and no option to get rid of them

**Developer response:** Thank you for your review.
We have now implemented a feature that allows users to completely turn off ads. We are also continuing to expand the app with more features to make learning ECGs enjoyable, and we update it regularly. We would be very happy if you gave it another try.

### 5/5 — アプデ求む

*2025-02-08*

正解が出ないので自分で調べたくなる。制限時間が短いのが惜しい。連続正解で大幅時間延長などの要素があるといい。
