HeartCloud offers extensive tools that let you do more with the workout and fitness functionality of your Apple Watch. View performance metrics for individual workout sessions, track workout-to-workout performance trends, and richly visualize, organize, compare, and search your entire workout history.

Dive Deeper

If you're a swimmer who uses an Apple Watch, you're probably used to fitness apps that show you some basic statistics like your lap time and stroke count. HeartCloud plunges far deeper into a combination of your swimming performance and cardiovascular health.



Lap-By-Lap Metrics

We start with the basics: each lap's time, stroke count, and lap distance. Then we add your minimum, maximum, and average heart rate per lap. The Apple Watch also can detect and record what style of lap (breast stroke, freestyle, backstroke, etc.) you're doing, and we show that recorded data on a per-lap basis right next to other important metrics so you can see which style you're most and least efficient at.

Lap-by-Lap Performance Variations

As a swimmer, it is important to know any variances between laps. Overall consistency in how fast and how long it takes to complete a lap should improve as you train more.

From lap to lap, HeartCloud shows you changes in your stroke count, lap time, and average heart rate between the current and prior lap. If a lap suddenly shows a spike in how many strokes it took to finish that lap, your average heart rate at that time might provide an indication of the anomaly.

Runs, Hikes, Walks, Cycling, and More

HeartCloud is incredible at visualizing workout sessions captured by the Apple Watch. These include runs (indoor and outdoor), hikes, walks (indoor and outdoor), cycling (indoor and outdoor), and elliptical workouts, just to name a few. HeartCloud uses the GPS and altitude metrics captured by the Watch and links historical weather data and rich maps. The resulting workout details include your workout route mapped with your speed, heart rate, altitude, mile times, weather during your workout, post-workout heart rate recovery, and heart rate zones.

Organize your Workout History

HeartCloud lets you organize and search your workout history based on location, weather, and date.



Mile Times

HeartCloud splits workout segments into individual miles, including the start and stop time for each. Each mile contains is calculated to include your average speed in miles and kilometers per hour, maximum and average heart rate, and the minimum and maximum altitude encountered during that mile.

Altitude and Speed

For every GPS recording, see your altitude, speed, and per-mile pace at every recorded GPS point. This gives you an extremely accurate picture at any point of your workout.



Workout Notes

The ability to take notes and record recollections about how your workout went can provide helpful support for diagnosing your performance or workout health data after the fact. HeartCloud provides a text editor so that you can write nicely-formatted notes to yourself.

Workout Maps

Location + Health Data

For every workout with recorded GPS data, HeartCloud displays your workout route in colored chunks indicating speed, altitude, and heart rate interpolated with your GPS data points.



Terrain and Trails Layer

Hikers and outdoor runners can see the topology on and around their workout routes.

Street Layer

For every workout with recorded GPS data, HeartCloud displays your workout route along the streets you ran, walked, or biked.



Satellite Layer

Your workout route if seen from space.

Mapped Heart Rate Zones

If your workout captured both heart rate and GPS data (which by default it will), HeartCloud can show you your heart rate zone along your workout route.


Workout Achievements

Track Your Wins

Achievements is what we call the part of HeartCloud that highlights you at your best. The results of your achievements will help you set more ambitious goals over time and help guide you to pushing yourself harder, faster, and more efficiently.

Track your fastest mile, your fastest swimming lap in the pool, your longest workout distance, and more. We're going to add so much to this throughout 2018 as suggestions from users have poured in.


Health-Centric Contexts to Workouts


Heart Rate During Each Mile

For workouts where your Apple Watch or iPhone captured GPS and distance data (virtually always), HeartCloud displays your mile times in the context of your heart rate during each second of each mile.

Heart Rate During Workout Sessions

HeartCloud shows what your heart rate was at any point across your workout. You can zoom in to see a particular time range more closely, with red and green color shifts respectively indicating decreases and increases in your heart rate during the workout session.

Heart Rate Zones

One factor in assessing how "normal" your heart rate is during a workout is your age. HeartCloud calculates your maximum estimated workout heart rate from your age and then shows you when you drop below, meet, or exceed that threshold.

Heart Rate + Altitude

Altitude changes are an important metric in analyzing a workout. Uniquely, HeartCloud can show you your heart rate in the context of these changes in altitude.



Workout-to-Workout Heart Trends

This HeartCloud Insight shows you your maximum and average heart rate for each type of Apple Watch workout (for example, a swim or a run). Over time, you can see how these trends in your heart rate exist for any type of workout.

About Post-Workout Heart Rate Recovery

How does heart rate recovery relate to your workout?

The concept behind heart rate recovery is that a person’s cardiovascular system becomes more active in response to the increased demands of exercise and then should drop and return to the resting state soon after the exercise is over. A greater drop in HR after stopping, and a shorter time to return to pre-workout resting values are generally considered to be desirable, as they indicate better cardiovascular health (Source: The New England Journal of Medicine). According to the National Emergency Medicine Association, heart rate recovery measures can be used to track changes from an exercise regimen. (Source: National Emergency Medicine Association).

What impacts heart rate recovery?

Besides regular exercise, some medications may impact heart rate recovery, either shortening or lengthening the time it takes to return to rest. HeartCloud Insights gives you the ability to monitor yourself and bring your data to your physician or other healthcare expert.


Workout Weather


Hyper-Local Weather

HeartCloud, as long as it has GPS data for your workout route, can deliver insanely-detailed metrics about ambient weather that may better inform your workout performance or location choice.


Weather Types

HeartCloud uses GPS coordinates and historical times to derive historical weather data for any of your workouts.
