How it works
Three steps. Measured every week.
Coaching that starts with data instead of guesses, and keeps checking the numbers as you train.
Baseline
Step 01: Assess
We track your performance data and establish a baseline: movement mechanics, speed, body movement, and how you recover between sessions.
Custom program
Step 02: Plan
A custom training program for each player, built from what the numbers say about you. Not a template, not a group drill sheet.
Real-time analytics
Step 03: Train & Measure
Hands-on sessions guided by real-time analytics, so every rep is measured and every week shows where you moved.
Coaching
On the field with Cooper.
Three ways to work together, all built on the same idea: know your numbers, then train what they tell you.
The platform
The coaching, in your pocket.
Everything from a session with Cooper lives in the app between sessions: the recovery check, the movement score, and the plan.
Readiness
Know how ready you are today.
Sleep, HRV, and strain from WHOOP roll into one daily readiness score, and the plan for the day is written around it.
- Connects to WHOOP in one tap
- A daily plan that adapts to recovery
- Streaks and week-over-week trends
Motion analysis
Film a rep, get a score.
Point a phone camera at a swing, shot, stride, or serve and PlayBetter draws a 17-keypoint skeleton over it, then grades the movement across 8 categories.
- 17-keypoint skeleton from a phone camera
- Scored across 8 movement categories
- Drills matched to your lowest score
Team
Your whole team, one screen.
Leaderboards, game recaps, and progress updates that parents actually read. Built for 8 sports, so a coach with two rosters keeps one login.
- Team leaderboards that update after every game
- Game recaps to share with families
- 8 sports, one roster view

Research
Research-backed.
Cooper studied 428 MLB pitchers before and after Tommy John surgery, ten seasons of Statcast, Baseball Savant, and Lahman data, analyzed in Python. The same rigor goes into every player's plan.

FAQ
Questions, answered.
The three things every parent and player asks first.
No. Programs are built case by case for every skill level, from a first travel-ball season to a varsity roster. The baseline assessment decides where we start.
