Selfloops – You can improve only what you measure

Why Wearable Compatibility Matters in Group Fitness

As wearable technology becomes increasingly common in the fitness industry, gyms and fitness clubs are facing an important operational question: should members be required to use a specific heart rate device, or should the platform adapt to the devices members already own?

For many facilities, flexibility and ease of onboarding are becoming key factors in member adoption and long-term engagement.

Supporting the Devices Members Already Use

SELFLOOPS Group Fitness is a group heart rate tracking service designed to support a wide range of wearable devices and heart rate technologies, allowing members to participate using equipment they are already familiar with.

The platform currently supports:

Whoop
Google Fitbit Air
Apple Watch
Wear OS
ANT+ heart rate devices, including products from brands such as Garmin, Polar, and Wahoo Fitness and many others.

This broad compatibility reduces friction during onboarding and eliminates the need for members to purchase additional hardware before participating in group fitness classes.

Reducing Operational Friction for Clubs and Franchises

For gyms operating at scale, compatibility can significantly impact both member experience and operational efficiency.

When members can connect devices they already own:

Setup time is reduced
Staff support requirements decrease
Adoption rates typically improve
Barriers to participation are minimized

This flexibility is particularly valuable for multi-location gyms and fitness franchises, where simplifying onboarding processes can have a meaningful effect across hundreds or thousands of members.

Optional Branded Heart Rate Devices

While many clubs prefer a bring-your-own-device approach, some facilities also choose to offer branded heart rate monitors as part of their ecosystem.

Providing club-branded devices can help reinforce brand identity inside the facility while giving members an additional option for participation. It also creates a more unified in-club experience for facilities that want tighter control over hardware deployment.

A Flexible Approach to Group Fitness Technology

Rather than locking facilities into a single hardware ecosystem, SELFLOOPS takes a platform-first approach focused on interoperability and scalability.

By supporting a broad range of wearables and heart rate technologies, clubs can implement group fitness tracking without disrupting the habits and device preferences of their members.

The result is a more accessible and scalable experience for both operators and participants.

STRENGTH TRAINING PLANS

One platform. Every discipline.

Strength training is evolving. Coaches and athletes expect more than spreadsheets, screenshots, and disconnected apps. They need a platform that simplifies programming, improves athlete engagement, and keeps all performance data in one place.

With the new Strength Training Plan creation feature from SELFLOOPS, coaches and personal trainers can now build professional strength programs, assign them to clients, and track every workout from a single platform.

From traditional strength training to HYROX, conditioning, running, cycling, and functional fitness, SELFLOOPS provides one ecosystem for every discipline.

Create Strength Training Plans in Minutes

The new Strength Training Plan Creator gives coaches complete flexibility to design structured workout programs for individuals or groups.

Programs can include:

Exercise instructions
Coach comments and notes
Video demonstrations for every exercise
Sets and repetitions
Weight prescriptions
RPE targets
%1RM targets

Coaches can quickly build reusable training templates and create their own exercise and workout library, making programming faster and more scalable over time.

Whether you coach strength athletes, personal training clients, or functional fitness classes, the platform adapts to your methodology.

Athletes Follow Workouts Directly From Their Smartphone

Clients can open the SELFLOOPS app on their smartphone and view their daily training session in a clean and structured format.

They can:

See the complete workout plan
Follow exercise instructions
Watch movement videos
Track sets, reps, and weights
Monitor workout progress in real time

Every completed workout is automatically stored inside the athlete’s training history for long-term analysis and coaching review.

More Than Strength Training

SELFLOOPS is not limited to strength workouts.

The same platform can also be used to create:

Running training plans
Cycling training plans
HYROX programs
CrossFit and conditioning workouts
Functional fitness sessions
Hybrid endurance-strength programming

Different sports require different performance metrics, and SELFLOOPS supports them all.

This allows coaches working with hybrid athletes and multi-disciplinary programs to manage everything inside one connected coaching ecosystem.

STRENGTH · HYROX · RUN · BIKE · CONDITIONING

One platform. Every discipline.

With the new Strength Training Plan creation tools, SELFLOOPS continues expanding its coaching ecosystem to help coaches, gyms, studios, and performance facilities deliver better training experiences across every sport and training methodology.

Whether your athletes lift in the gym, run outdoors, ride indoors, or train for hybrid competitions, SELFLOOPS provides the coaching tools to plan, monitor, analyze, and improve performance — all from one platform.

SELFLOOPS HRV — A New Era of Recovery & Performance

Back in October 2014, we launched the SELFLOOPS HRV app with a clear mission: bring professional-grade heart rate variability analysis to athletes and coaches everywhere.

Over the years, the app has been continuously improved. But this release is different.

This is a complete redesign—not just in how the app looks, but in how it helps you understand your body and train smarter.

A Fresh, Simpler Experience

The first thing you’ll notice is the new interface. It’s cleaner, faster, and built to make complex data easy to understand.

Your key metrics are now easier to read at a glance, and navigating the app feels more natural. Whether you’re checking your recovery in the morning or reviewing past sessions, everything is designed to be quick and intuitive.

Accuracy You Can Trust

SELFLOOPS HRV has always focused on accuracy, using precise beat-to-beat (R-R interval) data from Bluetooth heart rate monitors.

With this update, we’ve taken it a step further. Improved analysis and error correction bring the app closer than ever to state-of-the-art, professional-level accuracy—the kind trusted in elite sports and research.

This is not just a visual update. It’s a step forward in how physiological data can be used to support real-world performance decisions—for athletes, coaches, and organizations alike.

What’s new in the refresh:
→ Completely rebuilt interface — faster, cleaner, focused on your morning check-in
→ Trends analysis that shows your HRV trajectory over days and weeks
→ A Readiness Score that tells you when to push and when to recover
→ Full scientific metrics: RMSSD, ln(RMSSD), SDNN, pNN50, AVNN

The application can import R–R interval data from Apple Watch, as well as from any app that writes this data to HealthKit via the HealthKit API.

The Apple Watch automatically records R–R intervals throughout the day, but you can also trigger a dedicated HRV measurement using the Breathe app (now part of the Mindfulness app), which forces the watch to record and store R–R interval data in HealthKit. Once recorded, this session can be imported into the SELFLOOPS HRV app.

New: Trends & Readiness Score

One of the biggest additions is the introduction of Trends Analysis with the Readiness Score.

Instead of isolated data points, we now translate HRV into something actionable:
• Are you ready to perform?
• Are you accumulating fatigue?
• Are you improving over time?

This shift—from raw data to decision-support—is where we see the real value emerging. The app now looks at how your HRV evolves over time and turns that into a simple, actionable insight.

In practice, it’s straightforward:
• Measure your HRV daily, ideally in the morning
• Watch how your trend develops over time
• Use the Readiness Score to guide your training

When your readiness is high, it’s a good time to push. When it drops, your body may need recovery. It’s a smarter, more consistent way to train—based on how you actually feel, not just what’s planned.

Moving Forward

This redesign marks an important step forward for SELFLOOPS HRV. It’s faster, clearer, and more powerful—but still built around the same core idea: giving you reliable insights you can actually use.

Whether you’re a cyclist, runner, coach, or researcher — this is the tool that gives you an honest, accurate picture of your recovery and training readiness. No gimmicks, just data you can trust.

Available on the App Store and Google Play Store.

12 years later, we’re just getting started.

New Integration: SELFLOOPS × Health Sync

We’re excited to announce our new integration between SELFLOOPS and Health Sync, bringing together training, recovery, and lifestyle data into one unified performance platform.

With this integration, athletes and coaches can automatically sync sleep, HRV, resting heart rate, steps, activities, weight, and more into SELFLOOPS — from the Apple HealthKit and Google Health Connect with leading ecosystems including Garmin, Fitbit, Polar, Oura, Suunto, Coros, and many others.

This creates a single source of truth for performance and recovery insights, allowing coaches to make smarter decisions and athletes to train more effectively.

By consolidating data from multiple devices and platforms, SELFLOOPS now delivers a complete, continuous view of training load, recovery, and readiness, enabling truly data-driven coaching.

Because you can only improve what you measure.
