My diabetic life

I am a nurse and a very healthy person that contracted Covid 19 at work. I did not know that I had the virus except for the fact that my vision was different and I was urinating more frequently. These changes occurred over a one month period so I didn’t think much about it. When I did go to the doctor I was told that I was positive for the virus and that my blood glucose was 455. I didn’t feel sick no fever or cold like symptoms, just elevated blood glucose.. I stayed in the ICU room for about 2 days and then I went to a regular room…I was given insulin around the clock to return my glucose to a safe range, 250 before I was released…..Then my journey began, I am now diabetic…eating healthy, drinking more water, and most importantly, walking daily… I couldn’t have lost 49 pounds and monitored my vitals signs, and made all the necessary changes without the information provided to me by this app. It is my first line of defense, knowing. Knowing my numbers, heart rate, and being able to target my goals.. yes it is a great app.

Premium has a serious glitch(s)

The big advantage of the premium cardiogram app subscription is the ability of the app to alert you to elevated heart rate and low heart rates that could be indicative of a heart problem. You adjust the settings for high and low bpm. The default high heart rate setting is 129 beats per minute. The problem I have encountered numerous times since I started my subscription is that I get high heart rate notifications from cardiogram while I am working out in cardio sessions. These alerts come even though I have opened and am using my exercise app on Apple Watch 4 which syncs to cardiogram. Cardiogram app recognizes that I am in a workout as when I finish my workout by selecting end workout I get a nice workout display on the cardiogram app. I shouldn’t be receiving high heart rate alerts during a workout as I am trying to reach my target heart rate which is almost 150 bpm. Cardiogram premium should have different high heart rate alert settings: one for during workouts which for me might be 160 bpm and another for when I am not exercising which would be a lot lower. I agree I can change the settings before and after each exercise period but who will remember to do this and for the price of this app this should have been thought through.
Also at first I believed the premium app said they would respond to comments submitted thru the app in 24 hours. Now it says 4 business days. I sent an inquiry almost a week ago and have not had a response.

Developer Response ,

This is very helpful feedback, we're really sorry for not responding to your email. I've notified the team and we're working on a fix. We'd love to get more detail on the issue though—could you email me at harish@cardiogr.am?

Isuues and no help

So I had issues. Like I asked for them NOT to use my main EMAIL as I really don’t like the idea of what if they get hacked into like yahoo and others? I’d rather they used my throwaway Facebook account for me to use as a sign in and them to know my FB password as I really don’t care so much about it as I do my email account. I’ve emailed about it more than once and no one bothered to email back.
I had issues with my graphs not populating.... except for the Steps. But I have a Fitbit so that’s redundant. The main thing I wanted it for was to watch my heart and so far, it’s done a spectacularly crappy job at that. It doesn’t tell me a rhythm, only a high, doesn’t tell me a low. I’m trying to see what value it has OVER the HealthKit heart rate
I finally uninstalled it. Thanks for nothing guys. You were singularly unhelpful.

Update: Cardiogram support eventually got back to me and they reset my account. For those who have yet to open a Cardiogram account here is my advice. Make a throwaway email account to attach it to. Because they were nosy post on other formats. What business is it of theirs who my “friends” are? Oh and they’ll “ask permission before they post on your account”. Uh, I don’t want to take the time to say no. So upgrading from a 1 although I’m not sure how much more helpful it is than HealthKit truly. I have yet to see a aha moment

Developer Response ,

Hi Swetiepeti! I was going through our old reviews and just wanted to follow up on this. I thought you might be interested to know that last year, we made it possible for users to use Cardiogram without creating an account so users don't need to share their email if they don't want to.

I'm sorry to hear that it took such a long time for you to get a response to your concerns. We've made a lot of improvements to our support processes, so if you ever decide to give Cardiogram another try, we're here for you!

We've also added additional features (e.g., we do now show a low!) that will (hopefully) provide more value to our users, such as a journal section to track notes and symptoms, and multiple export formats for our Premium users.

In any event, thank you for being one of our earlier users and for taking the time to update your review! I hope all is well and that you're staying safe. If you have any thoughts or concerns, please feel to reach out to me directly at linda@cardiogr.am. Take care! ^Linda
