vbt
BarbellVBT measures real-time barbell velocity (m/s)
using your Apple Watch accelerometer — bringing
professional Velocity-Based Training (VBT) to everyone.
No expensive dedicated devices needed. Just your
Apple Watch.
【Scientifically Validated】
A 2023 study by the Swiss Federal Institute of Sport
(SFISM) and ETH Zurich confirmed that the wrist-worn
Apple Watch achieves barbell velocity measurement
accuracy (r = 0.952–0.965) equivalent to professional
VBT devices.

DOI: 10.3390/sports11070125)
【Key Features】
Real-Time Barbell Velocity
Measures vertical barbell velocity in real-time
using Apple Watch sensors. Displayed simultaneously
on iPhone speedometer.
8 Exercise Modes
Squat, Bench Press, Deadlift, Overhead Press,
Snatch, Clean, Kettlebell, and Custom mode.
Automatic Velocity Zone Classification
Automatically displays Power, Dynamic, SPD-STR,
Strength, and Max Strength zones based on
measured velocity.
Athlete History Management
Manage training data for multiple athletes
individually. Records peak velocity, rep count,
and velocity loss per set.
Ready Alert System
Detects stillness and notifies you when
measurement is ready via haptic feedback.
Velocity Loss Monitoring
Calculates real-time velocity loss compared to
the first rep in a set, providing an objective
measure of fatigue.
【Supported Devices】
iPhone (iOS 16 or later)
Apple Watch Series 4 or later (watchOS 9 or later)
【What is VBT?】
Velocity-Based Training is a scientific training
method that adjusts training intensity based on
barbell movement speed. A method used by elite
athletes — now accessible to everyone.

Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
The following features were added in this update.
· Weight (kg) Input
Record the load used for each set.
Enter before lifting or edit later from history.
· Automatic 1RM Estimation
With two or more weighted sets logged,
estimated 1RM is calculated from the load-velocity relationship.
· External Device Data Integration
Export iPhone measurement records as CSV,
then load them into the web dashboard alongside
data from other measurement devices.
· Nine New Analysis Charts
Load-Velocity profile, velocity loss distribution,
weekly trends, per-exercise PR progression,
volume-velocity balance, cross-system matrix,
Force-Velocity profile, regional strength trends.
· Refined Measurement Screen
Camera and Weight actions placed in central view,
auto-hidden during measurement.
· PDF Output Optimization
Full athlete report fits cleanly on three A4 pages
for handouts or archival use.
· Various improvements and stability fixes
