About this app

Revolutionise the way you train and prepare in the weights room!

The FLEX Stronger app syncs to a FLEX barbell sensor to deliver real-time feedback straight to your device.

Track, manage and review training performance just like elite and professional athletes right across the globe, through the Major Leagues, UFC, Premier League and Olympic institutes.

Developed by the team at GymAware, FLEX packages everything we learned from delivering gold standard products to the pro ranks into the only VBT system developed specifically for individual use.

The smartest system on the market, FLEX automates your entire training experience. Select an exercise. Load some weight. Lift. Completely wireless. No calibration, adjustments or exercise creation is required.

Perfect for individual athletes, remote coaches and personal trainers.

*Performance Metrics & Targets*

Precise and immediate feedback on Mean and Peak Velocity, Mean and Peak Power, Distance, Height, Position and live bar path tracing.

Set targets on key performance metrics to benchmark effort across your session.


Create connections in the FLEX community so you can browse their training history, download sessions (complete with their results), send workouts, train in groups. View session data live as it is uploaded set by set, and interact with fist bumps and comments directly on the platform.

*Store and Review*

All your data is stored and reviewable in History right in your app. Data is securely backed up on our servers and retrieved on your device at any time.

*Automated Workouts*

Save your training sessions as workouts to repeat later. FLEX will step you through every set, rep and weight change

What's new

In this version, you should notice that you are spending less time waiting around for things to happen. We’ve improved the login process, and reduced the time to load the exercise list and video list screens.

We also fixed a problem that caused a session edits not to be saved.
