HOW SURE ARE WE
Not in any grossing chart, so this comes from ratings growth (132 new ratings a month on average since launch): revenue grows with new ratings, more slowly for apps that collect ratings fast. Tested on 418 apps with verified revenue: typically off by about 2 times, and big earners tend to come out low. Countries we don't track (and Google Play in China, which doesn't exist) aren't included, and neither are ads or web payments. Gross revenue before store fees.

WHAT THEY ASK FOR

  • Additionally an option for users who are disabled to choose some other form of exercise would be nice. 5★, Feb 23, 2025
  • I ended up deleting app because it would display 4 or more HRV “needs attention” notifications a day. 2★, Nov 18, 2024
  • The only thing that would be nice to add on the app would be more advice on how to lower my heart rate especially when I sleep it says to not eat and exercise 3 hrs before sleep and no physical activity and no screen… 3★, Sep 21, 2023

★★★★★Oct 19, 2026
Early Detection of Pneumonia

Three weeks after surgery, one week after COVID, the alert for high heart rate went off over and over and over. High at rest. High when moving. High when sleeping. My blood oxygen was going down and I was getting those warning. Watch alerts were 5-10 times an hour. I did not have a cough. I was not easily out of breath. The next morning an x-ray showed the bottom left lobe was white on the X-ray. I had pneumonia. No symptoms except feeling agitated.

★★★★★Oct 11, 2026

I was getting Reports through September, but none during October. What’s going on?

Needs an update

Recent iOS updates broke the app. I am no longer getting updates for my cardio activity and all my old info is gone. Apple health is sharing with the app and yet, nothing. I’ve even reinstalled the app, set all permissions and it showed my info. Then the next open it had once again lost everything. I’m moving on.

★★★★★Sep 21, 2026
Saved my life

Because of this program on my Apple Watch I discovered I was having PVC’s showing my heart rate dropped below 40 for over 10 minutes and was able to have heart ablation to correct it. I’m so thankful.

Store description

Understand what your Apple Watch is telling you. CardioBot transforms your heart rate, Heart Rate Variability (HRV), stress, readiness, recovery, sleep, and activity into clear, personalized health insights—helping you better understand your body every day. Your Apple Watch continuously collects valuable health data, but individual numbers and charts only tell part of the story. CardioBot brings your health metrics together, reveals how they’re connected, and explains what changes over time may mean for your overall wellbeing. Built around your heart, CardioBot combines heart rate, HRV, stress, sleep, recovery, readiness, activity, and other Apple Watch vitals into one complete picture of your health. Discover how exercise, sleep, work, travel, illness, and everyday habits influence your body, recognize meaningful trends, and make more informed decisions about your routine. Health isn’t about a single measurement—it’s about understanding how your body changes over time. CardioBot helps you uncover patterns that are easy to miss and gives your Apple Watch data the context it deserves. With CardioBot, you can: * Understand your heart rate throughout the day, during sleep, exercise, and everyday life * Track Heart Rate Variability (HRV) alongside other Apple Watch health metrics * Follow stress patterns and better understand how daily life affects your body * See personalized readiness insights to understand whether your body appears prepared for activity * Monitor recovery trends and how sleep, stress, and activity influence them * Discover how your sleep affects recovery, readiness, and overall wellbeing * Identify long-term trends across heart health, stress, sleep, recovery, readiness, and activity * Receive clear, personalized insights instead of digging through scattered charts in Apple Health CardioBot is designed for everyday health awareness—not just fitness or training. Whether you’re improving sleep, managing stress, building healthier habits, staying active, or simply becoming more aware of your body, CardioBot helps you get more from the health data your Apple Watch already collects.
