ECG or Electrocardiography is one of the most useful clinical tools ever developed in the field of medicine. Learning about ECG is vital for almost every healthcare worker including paramedics, emergency staff, physicians, medical students, residents, and nurses. There are already tons of ECG resources to learn from but repetition is the key and this is the reason I came up with the idea of developing 'ECG Stat'. The app is very simple to use. It contains multiple categories ranging from ECG basics including ECG waveforms, intervals, segments to complicated ECG disease manifestations that users can access within seconds. I'm a strong advocate of visual learning and this is the reason I made sure to visualize every ECG feature in this app. If you search for 'Right bundle branch block', the app will quickly show you the core ECG changes seen in RBBB along with a visualization of those changes. Imagine yourself in a clinical setting where you're trying to recall the features of left atrial enlargement. Instead of googling for changes and then scrolling through thousands of images and search results, you can use the ECG Stat app to quickly look up the core ECG features seen in left atrial enlargement along with waveform changes! I have used multiple sources to create this app which is mentioned in the about section. The app is meant to be used by healthcare workers only. It's an educational tool and discrepancies can be seen. If you do find a mistake, you can easily report it through the contact form. The app is for educational purposes only and should not be solely relied on when it comes to patient care. I have strived to ensure that information contained in the app is accurate and personally created and reviewed all the images.

Verdict
The clearest difference is price: CorePendium at Free against ECG Stat's $2.99. CorePendium also leads on ratings volume (1.5K vs 2). ECG Stat's advantage is review sentiment (100% vs 62%) and iOS requirement (12.0 vs 15.1). On rating, ads, in-app purchases and device support there is nothing between them.
