Do I need a sensor attached to my baseball bat to use ProSwing?

No. ProSwing uses your smartphone camera and computer vision to analyze your baseball swing. It tracks 33 body joint landmarks in 3D without any bat knob sensors, launch monitors, or external hardware. Simply record your swing with your phone camera and the AI handles the rest.

Which mechanical flaws in a baseball swing can ProSwing detect?

ProSwing automatically detects and matches corrective drills for: casting (early arm extension), early extension (premature hip thrust toward the plate), sway (lateral weight shift away from target), lunging (weight transfers too early), hand drop (bat path drops below optimal plane), and poor hip-shoulder separation. Each flaw is flagged with severity and paired with a personalized video drill.

Sequence

Shohei Ohtani

Study the sequence from lower body through the barrel.

Speed

What to watch

1.Lower-body initiation
Watch the back hip start the move while the hands stay back. The legs fire first.
2.Torso rotation
Watch the chest stay closed a beat after the hips open. That gap is hip-shoulder separation.
3.Hand and barrel order
Watch the hands follow the torso, not race it. The barrel arrives last.
4.Contact position
Watch the front side hold firm at contact with the head steady over center.

How ProSwing measures it

You get graded on the same ideas in every analysis. These are the reads this swing teaches.

Sequence: Hips lead, hands follow
Speed: Movement turned into bat speed
