How will RocketBody help you?
The application analyzes the data a fitness tracker received. RocketBody uses EKG monitoring to track the metabolic rate and analyze it over time. These data determine the best time for you to train. All this information is combined with previous EKG readings into a trend curve that shows the dynamics of metabolic change over time. RocketBody’s algorithms then define the dependence of your metabolism on the input data (e.g. calories spent during workouts and calories gained with food).
Choosing the best time for training increases efficiency and reduces the risk of injury. RocketBody's algorithms adjust your metabolism to your schedule and let you work out when your body’s performance capacity is at its peak.

The application can not only analyze information but also make predictions. The analysis of physical activity will help to make a precise forecast of an athlete’s recovery for the coming week.

RocketBody AI designs workouts and nutrition based on metabolism data and other factors (e.g. goal, HR/HRV, calories gained/spent, etc.). It pulls in your diet from HealthKit so that you could easily manage it in one app.

A Neat and Interesting AI Companion

I happened to stumble upon this app and decided to give it a go upon reading that it uses Apple Watch 4’s ECG reading. Though skeptical at first due to how foreign this was to me, I have sent a copy of my ECG reading before, after, and in between workouts and I continue to be somewhat intrigued what it recommends to me: when I am ready, when it might be better to rest, and when I ought to consider staying put.

As of this post, I have not found any reason to remove this app from my phone and continue to want to play around with it. There is a subscription that goes along with this app that gives more. But without a subscription, you still are able to have this app’s AI read and interpret your ECG reading to tell you how ready you are for cardio and strength training.

I hope this helps someone out there. 🙂

I love it

The problem with this app is that the same time I do an exercise of it it thinks I do a outdoor run of the same time and location. I hope they fix it that way It does not say I did double the work

Great in concept, but missing features

There’s zero audio guidance while working out, so you have to keep looking at your phone. It’s very easy to miss transitions. The app also doesn’t share calories burned with the health app which makes it pretty useless in my mind. The Apple Watch app only works when you initiate a workout from your phone, and provides basically no value. It seems like they over indexed on a cool futuristic feature (ecg) but forgot all the basics of a good fitness app.

Developer Response ,

Thank you for your feedback. We improved the workout process in our latest release. Now it is more comfortable for a user to go through the workout. And also, we added sound alerts. Please update your app to the last version. To sync calories with the Health App, please check your health settings: Health App -> Profile -> Apps -> RocketBody and check you allow all the categories. We will be waiting for your new review ;) The New Apple Watch app is in development now.
