Use cases:
Velocity based training - Lift in the correct velocity range.
Power based training - Train to maximize power to increase vertical jump and explosiveness.
Olympic Lifting - Know if failed lift was technical (didn't get under the bar fast enough) or because of strength (bar did not reach adequate height to get under)
Correct form - Ensure the bar path is completely vertical, squat depth is low enough, catch is not too low during power clean, etc.

User's thoughts:
"I like seeing how fast I’m performing each rep for things like pause squats and more explosive Olympic lifts"
"Nice way to visualize how much time you have between reps"
"Let's me measure power on my lifts without having to spend lots of money"
"I've never been able to measure my workouts so easily before"

Don't waste hundreds of dollars buying inaccurate accelerometers or other bulky hardware to track the barbell. With just your phone and an inexpensive subscription, you'll have everything you need to optimize your training.
