What's New in Cardalis

2.6

July 6, 2026

Completely revamped app

User reviews

“server error”

Trying to create my first reminder, as it requires, and it just keeps saying ‘server error’

Deleted 6 years of data being tracked on my dog in CHF

It is so disappointing that this app updated and deleted all historical data saved. Users were forced to register for a new account. I have been using this app to check my dog’s heart rate since February 2020. This is data that are so clinically important for appropriate care of my dog in CHF. If given sufficient warning, I could have saved the data. Really disappointing.

What happened!

Now it doesn’t work. CONSTANT ERRORS

Lost all my data

Used to like this app but the update messed everything up. When I first got this app, it did not make you create a password to log in. The update requires you to use a password to log in now so I’m unable to access all my previous data, meaning I now have to start from scratch. As my vet is using this data to monitor my dog’s health, this is absolutely ridiculous for all that information to be completely lost.

Can’t create account

App was revamped 1 day ago. All my data is gone. I tried to create a new acct cause I forgot my credentials and no matter what combination of letters, capital letters, numbers, or characters I use, the Create Account button remains dithered.
