Developed for anyone who is interested in mastering the complexity of the electrical function of the heart. This app helps healthcare professionals and medical/nursing students gain deeper understanding of the ECG. It employs interactive real-time 3D exploration to aid learning of the cardiac rhythm. All text is available in English, German, Spanish, Mandarin 所有文字均以中文提供 and Greek. Tutorial voice over text is available in English. Use Apple Pencil or a soft rubber tip pen for better interaction. ECG is one of the most common diagnostics for Cardiology that all medical and nursing students are introduced at an early stage of their training. Confidence and experience gained from simulated training can help make first diagnosis successful and decrease risk to patients. This app uses real-time 3D anatomy and control of physiological parameters. Utilises electrophysiology simulation and live ECG signals to simulate the normal heart rhythm. APP FEATURES Introductory tutorial with voice-over Electrophysiology parameters: SA node switch on/off SA node rate 30-150bpm AV node block/unblock Escape Rhythm Live single lead ECG display Live 12-lead ECG display Annotated 12-lead ECG display Pause and scroll ECG with simultaneous action potential wavefront and 3d heart vector view ECG calliper tool Simulation speed control: Slow-Mo, Hi-Fi, Fast ECG speed control ECG voltage control ECG leads display with heart vector DCCV Cardioverter/Defibrillator Temporary pacing device with limited functions: On/off switch Pace indicator Interactive placement of pacing wire tip All other pacing parameters are disabled in this app. For fully functional pacemaker please see the Epicardio Temporary Cardiac Pacing app on AppStore. Anatomy views with free 3D camera control Choice of displayed anatomy Preset views General app settings: Sounds on/off Background colour options and brightness Screenshot info Tool tips on/off Languages: English, German, Spanish, Mandarin, Greek This app executes in landscape mode only TRAINING OBJECTIVES Understand what causes the ECG signals during normal sinus rhythm Explore the heart in 3D and gain spatial and temporal understanding of the heart's electrophysiology in normal sinus rhythm BENEFITS Mobility. Users can access individualised simulation training on their personal devices anytime and anywhere Guidance. Guided tutorials aid self-learning without the need for tutoring Model pacing outcomes. Normal vs. pathology overlays make it easy to visually compare differences in pacing that would otherwise need to be imagined Deeper understanding. Real-time interactive 3D anatomy and pacing wire placement provide spatial and temporal understanding of what causes the ECG signals and helps with retention Realistic simulation.

Contrary to an accepted misconception, slow reading does not make you better understand what you are reading. On the contrary, when we read slowly, our attention gets distracted much more quickly because we give our brains the spaces to think about other things by trying to read slowly. Thanks to this application, you will be able to scan pages much faster by improving your eye muscles, you will learn to read more than one word at the same time by expanding your vision, and you will improve your concentration with concentration exercises. You will read your pdf and epub files much faster with the help of the reader with 2 different modes. o Do the exercises set for you every day in the speed reading course. o Improve your eye muscles, visual angle and concentration ability thanks to the exercises. o After doing the daily exercises, read at least 20 minutes daily with the help of the reader. o Do extra exercises until your eye muscles get tired to improve faster. o Track your 30-day progress with statistics. o You will now read and understand your books much faster than before. o It makes it easier for you to spend time reading books. Features : • Speed reading and concentration exercises. • Reading accelerator for pdf and epub files in 2 different modes. • 30-day speed reading course. • Exercises for the eye muscles. • Exercises to expand the angle of vision. • EPUB reader and PDF reader feature. • Statistics to see your progress. • Spritz reading mode is perfect for reading books • Bionic reading. Who is this app for ? • Those who are distracted while reading a book and cannot read a book. • Those who want to read their books faster. • Those preparing for exams. • Those who want to improve their concentration.. • Those who want to read their epub and pdf books in spritz form.

Verdict

The call

The clearest difference is price: Speed reading at Free against Heart Simulator's $2.99. Speed reading also leads on rating (4.7 vs 2.3) and update cadence (every 5 weeks vs every 10 months). Heart Simulator's advantage is in-app purchases (none vs 3) and review sentiment (33% vs 25%). On ads and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Speed reading holds the better App Store score, 4.7 against 2.3. That said, the two scores are not equally well evidenced: Speed reading has 143 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 33% of Heart Simulator's written reviews are positive against 25% of Speed reading's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Heart Simulator ships an update every 10 months, Speed reading every 5 weeks. The most recent releases landed on October 15, 2026 and October 7, 2026 respectively.
