"SOUL FIT provides runners with real-time voice coaching function to maximize their running efficiency and minimize the risk of injury. The voice coaching function is based on the biomechanics data collected instantly from each run. And the data does not only include step counts, distance, speed and time, but also every aspect of your running motion with SOUL FIT and compatible earphones from SOUL.

Pair your compatible SOUL earphones with Beflex BiomechEngine® to your smartphone to start tracking your run. [1]

SOUL FIT delivers professional features to runners from different levels:

- Real-time voice coaching function to improve your running efficiency and minimize injury risk, based on various GAIT Analysis parameters (Cadence, Head angle, vertical oscillation, shock, step width and symmetry)
- Track and review your running activity (Distance, pace, speed, time, calories, step count, cadence and altitude)
- Analyze and review your running form (Head angle, vertical oscillation, flight-stance ratio, step width/ length)
- Analyze and review your injury risk (Shock, maximum force, leg stiffness, symmetry, consistency)

SOUL FIT will train you to be your best running coach!

Ratings and Reviews

RyanNystrom ,

Great tech, but app needs love

I got the Run Free as a gift for the holidays and it’s pretty special. Took it on my first run the other day and found the audio quality great, the coach helpful (and not too annoying), and they were comfortable too.

The app however is pretty rough.

- No integration with HealthKit. I want to record my workouts in one place.
- The UI is really bizarre. Would be 10x easier to use if it just followed Apple’s design guides.
- Crashed on me at least once but only while browsing data. Makes me nervous about crashing during a workout though!

That said, the data (real-time and post analysis) is just so cool. Really impressed, and modernizing the app a bit would make this a must-have!
