What is PitchPerfect?

PitchPerfect is a complete solution that makes measuring, storing and analyzing the biomechanics of baseball pitchers accessible for any baseball player anywhere, anytime.

What does PitchPerfect do?

PitchPerfect measures the rotation speed of the upper body (trunk) and lower body (hips) using sensors that are integrated in sports clothing. We measure the timing between upper- and lower body and count all your throws based on these measurements.

Why would I use PitchPerfect?

PitchPerfect is the first custom built system that provides you with information on biomechanical workload and automatically tracks pitch count anytime and anywhere. We believe that technological advances are the catalyst needed to bring sports and performance to new heights. Biomechanical information can be readily available for everybody; all it takes is wearing a sensor during sports.


How does PitchPerfect work?

The PitchPerfect sensors send data to your mobile devices with a Bluetooth connection. You can start and stop measuring using our free mobile App: PitchPerfect Baseball. Once you finished a training, the session data is stored on our cloud-based platform. Our platform allows for some basic insight in the App and gives you the opportunity for a deeper dive in the data on your personal dashboards.

Where does PitchPerfect come from?

PitchPerfect originated from scientific projects at the Vrije Universiteit Amsterdam and the Delft University of Technology. We started PitchPerfect as an independent company in 2021. We are collaborating with multiple Dutch industrial partners that help build our hardware components and create the PitchPerfect application and platform.


Where can I buy PitchPerfect?

You can acquire a full PitchPerfect set in our webshop at www.pitchperfect-baseball.com/shop

Or contact us directly via our social platforms or email.

How much does PitchPerfect cost?

A membership to PitchPerfect is 30€ month and is billed annually. A full PitchPerfect set (consisting of two sensors, a charging station with UCB-c cable and a shirt and short to wear the sensors) is included when acquiring the membership for the first time.

Addition clothing sets can be purchased for 39,95€.

What do I need a membership for?

The membership includes access to tracking and direct feedback functionality in the App. 24/7 data access on the app and dashboards, and personalized dashboards with the option to add an edit data online.


Do you ship to my country?

We are currently shipping to all European countries. Shipping to the US is expected to start in the first quarter of 2022.

How do I turn the sensor on and off?

Press the button on the back of the sensor for 3 seconds. A double light flash indicates you turned the sensor on. When the sensor is on a light will flash every 3 seconds.

How do I connect the sensors to the app?

Please check the instructions in the App. You can find them in the ‘settings’ menu bij clicking the yellow question mark.

How long do the sensor batteries last?

Sensor batteries will last at least for a full day


Does PitchPerfect require an internet connection?

You need to be online to log-in to the app, but using the app does not require an internet connection.

Can I run the app in the background on my phone while recording?

Yes. The sensor tracks all your throws after you have started the tracking function. After tracking has been started, you do not need to run the application in the foreground to continue tracking.

Do I need to constantly stay connected to my phone while pitching?

The sensors measure and store information independently of the app after you have started them using the tracking mode with the PitchPerfect Baseball App. Make sure to collect and sync the data from the sensors after your training session by clicking the end session/save data button.

Can I measure my ball velocity using PitchPerfect?

PitchPerfect is developed to measure biomechanics in the field, it does not measure ball(flight) information.


What does 'rotation speed' mean?

Rotation speed is the value that described how fast an object is rotating around the centre of itself. Rotation speed is measured in the degrees per second and 360 degrees per second mean one full rotation in one second.

What is 'separation time'?

During the pitch the hips and trunk are rotating. We measure the moment in time when the segment is rotating at it’s fastest and compare this moment between the upper body (trunk) and lower body (hips). The timing between upper and lower body is crucial in transferring energy through the body and creating maximal throwing velocity. We measure this timing in milliseconds (ms). Scientific research has demonstrated that elite throwers rotate their upper body after their lower body (on average 35ms).

Am I the only person that has access to my data?

Your data can only be accessed after login to the app or online dashboards. We are continuously developing our platform and working on functions to easily share data with your team and/or coaches.

Can I share my pitching data with my coach?

At the moment we do not have a sharing function on our platform. We are continuously developing our platform and except to release a sharing function soon.


My sensors aren’t being detected by my phone.

Make sure the sensor are on, and a green light is blinking. Make sure your Bluetooth is on. Check if your app is allowed to access your Bluetooth protocol.

Does it matter if I pitch left-handed or right-handed?

We measure body mechanics, therefore is does not differentiate between left and right handed throwing.

Does PitchPerfect work for other sports?

The biomechanical basis of baseball pitching relies on upper- and lower-body coordination which are similar between overhand throwing sport such as the baseball pitch, a tennis serve or a javelin throw. However, the tracking algorithm is optimized for baseball pitchers.

At what level can PitchPerfect be used?

PitchPerfect can be used by pitchers playing on all levels from beginner/ high school to the pro-leagues. We advise young pitchers to start working with PitchPerfect from an age as early as 13 years old.

I am a coach and want my pitchers to use PitchPerfect?

That’s great! If you want us to help explain PitchPerfect to your players or are interested in a demonstration at your facility, please send us a message on our socials or by email at info@pitchperfect-baseball.com

What languages does PitchPerfect support?

The app automatically adjusts to the standard language of your phone.
