Hitting Metrics – MTRx is a new app for Baseball, Softball, and Cricket batters of all ages and skill levels.

This app will help you improve important aspects of your hitting:

  • Core speed and quickness for bat speed and power.
  • Load and impact position of hips to enable hitting to all fields.
  • Switch hitting with consistent metrics from both sides of the plate.

Hitting MTRx will measure the rotation of your hips at Load and Impact positions. The correct rotation is critical for getting into position to hit balls that are inside, middle, or outside.

The measured Velocity reported for each swing is the top speed in degrees per second that your hips reach during the swing. Use velocity as a reference to see how hip speed affects your hitting.

The time in seconds shows how quick your swing is from the point you start after loading to the impact of the bat with the ball. Developing quickness from your core through the shoulders, arms and bat is critical to improving power and bat speed.

With the iPhone secured to your waist, the app uses the microphone, gyroscope and motion detector on the iPhone to detect and record swings. When you take your stance, load, stride, swing and contact the ball, the app records key data points. These include the rotation, velocity, speed, and timing of your swing. The microphone is used to determine the impact point.

The important swing data is displayed in simple formats that provide instant feedback about your swing.

MTRx has an intelligent swing recognition algorithm designed to record only real swings that contact a ball. Motion and sound data is analyzed 100 times each second so the data is highly accurate.

Your privacy is protected. During swing recording, no personal information is recorded or saved. The microphone is only used to listen for peak power of audio levels and the app does not listen to or record vocal conversation.

Record Your Swings

Press the Start Recording button when you are ready to record your swings.

Place the iPhone top down into the waistband of your pants. The middle of the iPhone should be behind your belt. Make sure it is secure so it won’t slide around.

Holders that strap around your waist work very well. These holders can be ordered from many online retailers. Strap holders are recommended because they keep the iPhone firmly against your hip to ensure accurate data.

Take your stance position ready to hit. Keep your hips still for at least one second. Start your swing and hit the ball from a tee or using soft toss, following through to a finish position. MTRx will play a “ding” sound when your swing is recorded successfully.

There must be an impact sound. Swings without a contact sound will not record.


  • Recording swings from live pitching or batting machines is not recommended. MTRx data may be inaccurate if you miss the pitch and the ball hits the catcher’s mitt or the backstop.
  • Wild pitches could damage your iPhone.

The iPhone or iPod touch can be in front or back. It can be offset to either side wherever it is most comfortable. The side of your hip is not recommended.

Orientation of the iPhone does not matter. It can be portrait or landscape, facing toward or away from your body. Try to keep it top up or down, or on either side, parallel or perpendicular to the ground.

Core speed and quickness for bat speed and power.

All hitters want to develop more bat speed which can result in more power. Bat speed is the result of many factors and one of the most important is the rotational power and quickness generated by your core, specifically your hips. The Hitting Metrics app provides two key data points critical to creating bat speed.

  1. The first is the angular velocity your hips reach during the swing. The velocity metric is measured in degrees per second. The faster your hips turn forward in the swing, the higher the measured velocity. The goal here is to learn to increase your hip velocity. You must maintain control of your speed; swinging too hard can cause a loss of stability and balance.
  2. The second is time from load to impact. The app measures this time from the point your hips start forward to the point the bat makes contact with the ball. The time metric depends on how quick you get your hips to peak velocity and how fast your torso, arms, and hands can deliver the bat to the ball. The faster you do that, the lower your time from load to impact will be.

Good velocity and a quick time to impact give you more time to see the pitch before committing to the swing.

Load and impact position of hips to enable hitting to all fields.

The Hitting Metrics app measures hip rotation as you load and at impact as you hit the ball.

Load is the number of degrees your hips rotate back at the start of your swing. Some hitters have little or no load while others start with an open stance and load 20 degrees or more. There is no single load number that is right for everyone. You just need to find the load that works best for you. Whatever load metric you use, it must allow you to get your hips to the right rotation at impact.

Hip rotation at impact should vary depending on the location of the pitch. To hit an inside pitch, the hips must rotate fully from 65 up to 100 degrees. This is necessary to allow your torso, arms and hands to deliver the bat to the ball in front of the plate.

But if you rotate that much on an outside pitch, your front side will open and you may not reach the ball. For pitches on the outer half of the plate your hips should be about 40 to 75 degrees open at impact. This allows you to contact the ball a little later and hit it with power to the opposite field.

For pitches in the middle, your hips should rotate between 50 and 90 degrees.

Placement of the tee or soft toss pitches should vary for pitches in, down the middle, and away. For inside pitches, place the tee on the inner half and 6 to 10 inches in front of the plate. For pitches in the middle, hit the ball from the tee or toss on the middle and front edge of the plate. For outside pitches, the tee or pitch should be on the plate’s outer half and 6 to 10 inches behind the front edge.

Switch hitting with consistent metrics from both sides of the plate.

To be a successful switch hitter you must be able to handle pitches both in and away equally well from either side. If you can only pull the ball from the right side, pitchers will adjust and throw outside. If your velocity and time from load to impact are better from the left side, then you need to improve those metrics from the right side.

Use Hitting Metrics to compare your numbers from both sides for pitches in all locations. Differences in the metrics will identify where you need to improve.
