Announcing Moxy support

We are happy to announce that we have included the support for Moxy.

Moxy is an innovative device that uses infrared light to continuously monitor oxygen saturation (SmO₂) levels in the muscles of athletes while they exercise.
Oxygen is the fuel that drives the muscle, and Muscle Oxygen levels are constantly changing.
Moxy is used to assess athletes, guide their training, and hone their performance during competition. It helps identify optimal training intensity zones and provides feedback on the physiologic systems limiting performance.


Now with SelfLoops you can analyze how the Total Hemoglobin Concentration (THb measured in g/dL) and the Percentage of hemoglobin saturated with oxygen (Smo2 %) vary while exercising.

These are additional metrics that can be used to evaluate and measure your trainings.

Since Moxy conforms to the ANT+ Muscle Oxygen profile, we have added this profile to our indoor bike power training service. Basically, train with our app, automatically upload your data on SelfLoops and get all the analysis on your workout, including THb and and Smo2, on the SelfLoops website.

You can only improve what you measure!

Advanced Running Metrics on SelfLoops

We now have a set of advanced metrics for runners. There is the Pace of course, but also the GAP (Grade Adjusted Pace) that estimates an equivalent pace when running on flat land. Because running uphill requires extra effort, the GAP shown will be faster than the actual pace you ran. When running downhill, the GAP will be slower than the actual pace. As a reference for GAP, see for example “Pace and Critical Gradient for Hill Runners: An Analysis of Race Records“, Anthony Kay.

In addition there are the Splits, Laps and the possibility to select areas to analyze in more detail.

Set your Goals and Track your Progresses

You can only improve what you measure. And you need to set goals and be able to track your progresses.

We have added the ability to set your weekly goals and track them. You can set your objectives in terms of number of activities, hours spent or distance. We believe we have added an important tools for people that are serious about their trainings.

If you have not done it yet, sign up to our SelfLoops website.



Calculating your Heart Rate Variability with SelfLoops

The SelfLoops HRV application calculates and displays the heart rate variability.

Heart rate variability (HRV) is the physiological phenomenon of variation in the time interval between heartbeats. It is measured by the variation in the beat-to-beat (called R-R) intervals. For an intro to HRV see:

The metrics calculated at the moment are: SDNN, RMSSD, pNN50, AVNN.

To use the application you need a Bluetooth Low Energy heart rate monitor. We have personally tested the application with the Viiiva, Wahoo BlueHR and Polar H7 heart rate monitors.
The Viiiva is available at our store:

If you record the session you will be able to export the data, saved in csv format, to Dropbox, Google Drive, by email etc, and open it using Microsoft Excel, a text editor, Apple Numbers.

By using the application you expressly agree that SelfLoops is not providing medical advice with this application. Please, consult or ask for the advice to your physician or other medical professionals for any health related questions.
