RELATED: The Best Activity And Fitness Trackers For Parents ShotTracker’s actually made up three parts: A water-resistant motion sensor that’s worn on the shooting arm and records shot attempts; a net sensor that tallies makes and misses; and a smartphone app that not only monitors all the stats in real time but also displays where on the court a player’s game is the strongest. Hit 25 straight treys from the top of the key, and you’ll see a “25/25,” “75 Points Scored,” and the time it took you do it. The set comes with a charger and washable wristband (in which to put the sensor), but for $20 extra you can upgrade to a breathable mesh full arm sleeve. For $50, you can get an elite compression shooting shirt. In addition to doing all that counting, ShotTracker also plays the part of coach ⏤ mind you, one who doesn’t make you run full-court sprints when you miss a free throw. It comes pre-loaded with hundreds of pro-designed drills and workouts, all engineered to make practice sessions more fun and effective. And finally, if you’re also coaching your kid’s rec league squad and want to keep detailed stats on every 5-year-old who chucks the ball, there’s a much more expensive (as in $3,000 more) ShotTracker TEAM version that uses shoe and court sensors, and a special ball to monitor live action/stats on your tablet.
