For a medical company, it’s a pretty bad app for what they charge.

Using a ZIO patch to collect information about your heart is not cheap (the materials that come with it are very open about finding assistance and payment plans) and the tech is cool, I love how small and portable the device is. When this millennial saw that I could log my symptoms with an app rather than write them down, I was thrilled.

My biggest issue is that you want to start filling out your symptoms the moment they occur. The feelings are front of mind, so after tapping my ZIO patch, I would open the app, enter the time, the symptoms, the activity, then I would wait to see how long the symptoms would last. If you let you open another app or ignore the MY ZIO app and your phone falls asleep, it forced you to log all of your info from the beginning. Because of this glitch I feel like I have missed a few logs.

There are also notifications that show up on the app and it is completely unclear as to what those notifications pertain to. I would think that iRhythm could take some of their massive profits and invest them in these customer facing applications.

App is so so

It’s a pretty basic app. But the messages that Zio sends can’t be read because they disappear when you click on them. Surely this corporation must be aware that they have a glitch happening with messaging. Why don’t they fix it? My other issue is that they don’t provide enough characters to adequately describe a symptom. This is the patient’s opportunity to convey important information to the doctor that could be helpful in making an accurate diagnosis. So why limit it to 75 characters? I mean really, even Trump gets 140 characters for his ridiculous Tweets. Why do we only get half that for something important like our hearts?

Less than zero

First 20 hours were a nightmare. Surprised that grief with the app didn’t cause a cardiac event in itself (I’m very tech-savvy). Had to call the manufacture five times, and my cardio provider twice. Thank you, Xanax. Very nice customer service people! But two out of three had telephone headsets that didn’t work - and they were aware of it! 90% frustrating static and unintelligible, so I had to keep calling back. Very poor app development for such a vital healthcare tool. Registering the app is nearly impossible! Deleting and reinstalling the app doesn’t help. One registration error and you’re locked out for another day. Once you remove the patch, all your info will go to the company (so complaints could be redacted) not your doctor, so there’s one more weak link in the chain. Also, any cardiac events are stored on a chip in the device, as opposed to transmitted wirelessly. Therefore, they will only find out about your heart attack when they analyze the data on the device around the time of your funeral. Yes, friendlier hardware than the Holter monitor, but falls far short in medical value. With all the one-star reviews, it’s amazing that the average number of stars shown is 2.8 out of 5!
