Revolutionize Your Game

Multi-Sport Mastery At Your Fingertips

The App features 3 unique sport modes, with unique setting programmed into the app for each sport:

  • Baseball
  • Softball
  • Tennis

You can measure, record, and track throws between bases, exit velocity, serve and return speeds in tennis, and even how fast a runner dashes around the diamond in baseball and softball. If it is in motion, it can be measured, as Peter Drucker once said, “What gets measured gets improved.”

Easy to use, especially with the hands-off Auto Capture Mode, the Stalker Sport App is a must-have for scouts, coaches, trainers, players, and parents – anyone who is focused on continuous improvement.

Stadium Mode

Turn Your Device Into A Speed Display

Convert your iPhone or iPad into a high-visibility speed sign that shows peak velocity, rolldown, and spin rate*.

*(Spin rate only displayed when paired with the Pro 3s).

Perfect for:

  • Instant feedback for players
  • Team motivation during practice
  • Fan engagement during games
  • Professional presentation for scouts and recruiters

Velocity And Spin Rate

In The Palm Of Your Hand

Players can be categorized by name and team, and organized by Action (pitching, hitting, fielding) and Pitch Type. Ball Spin Rate (using the Pro 3s), Peak Velo, and Rolldown Speeds are displayed and recorded in real time.

Track Your Entire Team, All From One App

The Stalker Sport App is powerful enough to store data from multiple players. Players can be labeled by their name and team. You can even track and label data from players on competing teams for analysis.

Statistics are saved to your history where you can then download, edit, and share.

High-Definition Video

With Zoom-In, Slow Motion, And Auto Mode

Customize your video recording settings with your choice of 3 resolution options and 3 different frame rate (FPS) selections.

Slow-motion recording lets you observe important details like finger positioning, player body alignment, follow-through, pitch break/drop, and more. You can even zoom in for a more detailed look.

Edit And Share

The Stalker Sport App makes it simple to share videos and stats with players, coaches, scouts, or parents. Create new clips from full recordings while keeping your originals intact, then overlay performance data like Peak Velo, Rolldown, and Spin Rate (Pro 3s).

You can also add notes, player details, and even your team logo, automatically embedded on every video. Saved in MP4 format, clips are easy to share through email, social media, Airdrop, and more.

Built For Serious Player Development

Accurate tracking data and statistics are vital to developing players to their full potential. The Stalker Sport App works hand-in-hand with the most trusted radar guns in the industry - the Pro 3s, Pro 3, and Sport 3 Connect - to deliver unmatched accuracy you can rely on.

  • Store data directly on your phone for instant access
  • Export as .csv files for Excel and spreadsheet analysis
  • JSON format export for cloud and application integration
  • Advanced filtering by pitch type, speed, player name, and more
  • Extract exact information you need from each session

And when you use the Automatic Video Recording feature, you can set up your phone and radar to record pitches, hits, or throws throughout entire practice sessions and games, which allows you to understand and track how player performance changes throughout the day.
