The app uses the iPhone’s gyroscope to set all three angles of the upper assembly of the Quant Tee device. 3D graphics of the target angles and the actual angles are provided for easy set up. Once the upper unit has been set for a particular pitch location, the iPhone is removed via quick-release attachment and safely stored while training. The Quant Tee App is highly customizable and allows users to input custom parameters including Launch Angle, Vertical Bat Angle, and Pull/Opposite Field hitting preference.

The total amount of bat loft at and around the contact point is very complex. As hitters react to pitch location - early on inside pitches and later on outside pitches, there is a significant impact on total bat loft that needs to be considered. The best hitters are adjusting to this "Implicit Loft" in order to keep the total bat loft consistent. Manipulating the 3D graphic in the app makes this complex relationship between Implicit, Explicit, and Total Loft very easy to understand.

The Quant Tee app and device are based on years of data and hard evidence of what the best hitters are actually doing. Even among professional hitters, those who hit the ball more square (less backspin) and have more consistent launch angles outperform everyone else. 

It’s time to ditch hitting “philosophies” and rely on mechanics supported by hard evidence!
