What's New in Cardalis

2.6

July 6, 2026

Completely revamped app

User reviews

Clunky.

This app is not easy to use and lacks so easy refinements such as your dogs picture on the page - easy to do but not available. Also when you go into the heart monitoring page why use the image of a ‘heart’ to represent a breath, why not not a cloud or a balloon or anything else but a heart which makes you think that you are monitoring heart rate rather than than breath rate!

Used to be a great app

This app used to have a function allowing data to be emailed to the cardiologist. Now it is extremely difficult to transfer the data.

Notes?

Where do the notes go? And, why can’t you add a note if you need to, or modify? What is the sense of notes?

Could be better

Been using this for years to monitor my dogs breathing rate. Would LOVE to be able to scroll on the graph to clearly see the dates and results.
