Film study for regular kids

College and pro athletes spend hours watching film of themselves. They can afford coaches with fancy software. In 2026, your $800 iPhone plus a free app does most of what a $20,000 pro setup did 5 years ago. This is a huge unlock.

The tools

HomeCourt: basketball shot analysis, tracks made/missed and form
OnForm: tennis, golf, swim, any sport - slow-mo with markup
Dartfish: the pro choice for high schools, used by NCAA coaches
Kinovea: free desktop video analysis (free!)
Hudl: team film analysis, used by 90% of high school football
Apple Fitness+: guided workouts with AI form checks on your iPhone

HomeCourt vs. Dartfish for students

HomeCourt (consumer)	Dartfish (pro)
Just open iPhone, start shooting	Needs more setup, but deeper features
Great for solo basketball practice	Great for team film sessions
Free with Pro tier at $15/mo	School subscription, often thousands
Instant feedback on your shot	Detailed biomechanical measurements
Best for self-improvement	Best for coaching decisions

A real workout with AI

Set up your phone on a mini tripod (like $10 on Amazon)
Open HomeCourt or OnForm in practice mode
Do your drill (jumpshots, tennis serves, swim laps)
Review the AI markup: arm angle, foot placement, release timing
Pick ONE thing to fix next rep
Do another 10 reps with that fix in mind
Review again. See improvement.

What AI can see

Joint angles (elbow, knee, hip)
Speed of movement
Path of the ball or body
Consistency across reps
Side-by-side comparison with pros
Simple things like 'your left hand dropped'

What AI cannot see

How tired you are
Game situation pressure
Strategy and reading the defense
Your mental state
Injuries building up silently

Nutrition and sleep tools

MyFitnessPal + AI: tracks what you eat, suggests balance
Oura Ring / Whoop: measures sleep and recovery, gives AI-based suggestions
Apple Health: aggregates all your health data, AI insights coming

You do not rise to the level of your goals. You fall to the level of your systems.
— James Clear

The big idea: AI video analysis is coach-quality feedback in your pocket. Use it to fix one small thing at a time. Respect what AI cannot see - your body, your rest, and your real coach's eye.
