What's New in ECG Tracker+ EKG Reader HRV

1.3.7

October 25, 2026

This update brings support for iPhone Duo and improves the layout on iPad, with a two-column Library that makes better use of the larger screen. As always, we also polished a number of smaller things and refreshed the design in a few places for a smoother, more reliable experience. ECG Tracker+ is an informational measurement tool and is not a medical device. It can make mistakes, and measurements may be affected by signal noise or recording artifacts. Possible findings, including possible premature beats, are shown for information only and are not a diagnosis. It does not provide medical advice, diagnosis, or treatment. Always consult a qualified medical professional about your ECG or health concerns. If you think you may be experiencing a medical emergency, contact your local emergency services immediately.

DO NOT TRUST…

...𝗧𝗛𝗘 𝗡𝗘𝗚𝗔𝗧𝗜𝗩𝗘 𝗥𝗘𝗩𝗜𝗘𝗪𝗦!!

This young developer is absolutely gifted!
The app is crafted with genius!

Enjoy the smooth and delightful communication between the Watch and the iPhone.

Take the ECG on the Apple Watch—isn't it extraordinary?—and read the results' transcript in just seconds! (Just make sure your phone is unlocked!)

The Watch App is truly a masterpiece. The clarity is simply breathtaking, and once you get the hang of it, you'll absolutely fall in love with it!

The Settings section is not only for making adjustments! It is a mini encyclopedia of valuable knowledge that will definitely assist in learning terminology, and overall understanding!!

The price of the one-time Lifetime subscription is a treasure on its own because with the surge of upcoming updates, and additions to the app’s arsenal, it’s destined to be the top choice in its category!

To the Developer:
Exceptionally well done!!
Bravo!!!❤️❤️

Thank you so much for your incredibly kind words and for taking the time to leave such a thoughtful review. I’m very happy to hear that the application is meeting your expectations and that you’re enjoying the experience across both the iPhone and Apple Watch. Your feedback and support mean a lot and are a great motivation to keep improving ECG Tracker+ and adding useful new features. Thank you again for your support!

Dangerous: causing harm

It gives diagnostic results without regulatory clearance, which can cause potential harm if i believed what it says that my qtc is long as it said.

Searched their claims and found no regulatory info but disclaims that it is not diagnostic

The developer must believe the disclaimer can protect them. It’s like saying you may have cancer but this is not a diagnosis… this is harm caused regardless

Response from developer

Thank you for sharing your concern. ECG Tracker+ is an informational tool. “Possible QTc above threshold” describes an estimated measurement, not a diagnosis of a heart condition. We make this clear in multiple places throughout the app, including measurement explanations and safety notices: results can be inaccurate and should not guide treatment decisions. Measurements and any health concerns should be discussed with a qualified clinician.

I don’t trust the app

A genuine review from someone suffering pac: I found it replicated ecg plus’ feature, for example scrubbing and tapping to locate a beat. I think this is a learn and copy tactic used by many, problem is for medical apps developers credibility is important.

Update: LYING to ur users is way worse than being up front, you didn’t independently develop the app when you just replicate which is so easy to do nowadays. Many apps learn from existing apps, which I don’t think is wrong, common to see, but dishonesty means you cannot be trusted I am sorry to say

Response from developer

Thanks for taking another look and updating your review. ECG Tracker+ was developed independently. Shared gestures such as scrolling a waveform or tapping a beat are common interface patterns. We respect your preference for another app and believe competition gives users more choice. We welcome specific feedback about your experience through Support in the app.

Full of ChatGPT languages

The developer’s English is either taught by ChatGPT or the app is built by ChatGPT

Response from developer

Thank you for your feedback. If any wording in the app felt unclear or unnatural, I’d appreciate a specific example so I can improve it. I’m committed to making ECG Tracker+ clear and easy to use, and feedback about your experience helps me do that. Please use the Contact Support option in the app to share more details so I can follow up with you directly.
