AccelIntel: Velocity-Based Training App for iPhone and Apple Watch

Train Smarter.
Move Faster.
Get Stronger.

AccelIntel is a velocity-based training app for iPhone and Apple Watch. It helps athletes, lifters, sprinters, and coaches measure bar speed, track velocity loss, monitor fatigue, and train in the right VBT zone. AccelIntel is designed to help strength training support power, explosiveness, acceleration, and speed-focused performance.

Weight Only Tells Part of the Story

Traditional lifting tells you how much weight you lifted.
AccelIntel shows how well you moved it.

AccelIntel gives you real movement data so you know:
• when to increase weight
• when to stop a workout
• whether your speed and strength are improving

What Is Velocity-Based Training?

Velocity-based training uses rep speed to estimate effort, fatigue, and training intensity. Instead of relying only on weight, AccelIntel helps you understand how each rep was actually performed.

AccelIntel uses real movement data from your Apple Watch to guide your training in real time.

With every workout, you’ll know:
✓ When to increase weight
✓ When fatigue is building
✓ Whether your bar speed is improving
✓ Whether you’re training in the right zone

Real-Time Velocity Tracking

Measure bar speed on every rep.

AccelIntel captures movement from your Apple Watch and turns each set into useful training feedback.

Smart Load Recommendations

Know when to increase, maintain, or reduce.

AccelIntel compares your recent velocity, fatigue, and consistency trends so you can adjust load with more confidence.

Train in the Right Zone

Hit the correct intensity every workout.

AccelIntel helps you stay in the velocity zone that matches your goal — power, strength-speed, speed-strength, or max strength.
