Angular Baseball gives hitting coaches a scored swing report for every player on the roster. Film a swing on your phone, and in about 30 seconds you have the breakdown, a slow-motion skeleton replay, and the drills to fix what it found. Free to start. BUILT FOR COACHES • Your roster, by team. Group players by team and filter in one tap. Archive a player at season's end and every swing stays on file. • Tap Record, pick who's hitting. The swing lands in that player's history. Players don't need their own account. • One take, one baseline. Film 5–15 swings off the tee and get a baseline report: a five-phase scorecard and the three things to fix first, with the swings that show each one. • Your voice on every report. Add your own notes on top of the AI analysis, so the family hears it from you. • Reports parents actually open. Share a baseline report by link, or email a session recap under your name. Parents don't need the app or an account to read it. • Bring families in. Invite a parent, and they follow their player's swings and your notes in the app. • Know who's next. Coach Home shows who still needs a baseline. Activity groups every player's swings by day, with their baseline pinned on top. • Show the progress. Check in with a new swing, scored against that player's baseline. FOR PLAYERS Every swing is saved. Watch your score move, compare sessions side by side, and keep a record of what is actually improving. FOR PARENTS You don't have to know what a good swing looks like. Film your kid from the side with the phone you already have. The app scores the whole swing — setup, load, stride, contact, follow-through — then tells you in plain English which fix comes first and the drill that fixes it. WHAT THE REPORT MEASURES Pose detection tracks 33 body landmarks through every frame, then scores the mechanics against bands calibrated on elite swings: • Setup — stance width, knee flex, balance • Load — back-knee stability • Stride — timing versus launch, forward move to the pitcher • Contact — trunk lean, back elbow, front-leg brace, lead-shoulder rotation, swing plane • Follow-through — hand speed through the zone Every issue is ranked high, medium, or low severity, so you know what to work on first, and each one comes with the specific drill for it. SEE IT, DON'T JUST READ IT Each report plays the swing back in slow motion with the skeleton overlay and phase markers drawn on it, so the fault is something you can watch, not just a number on a card. Export a shareable report card in one tap. THE 3-WEEK FOCUS PROGRAM Start from a baseline, pick two focus areas, and the app builds a 6-session plan: two sessions a week for three weeks — learn one cue, then the next, then both at game speed. Every session re-scores both focus areas, and a Final Check re-runs the full scorecard for a real before-and-after. DRILLS THAT MATCH THE DIAGNOSIS 20 drills across 8 focus areas, prescribed by what the swing actually showed — not a generic list handed to everyone. FREE TO START Free coach accounts get one analysis per player per day, up to 20 a week. Players and parents get 2 swings a day and 5 a week. No card required to see your first full report. Pro removes the limits. WHO IT'S FOR Hitting instructors, travel-ball and high school coaches, and the players and parents they work with. Baseball and softball, right- and left-handed swings. HOW TO FILM IT (30 SECONDS OF SETUP) Stand perpendicular to the hitter — from the side, not behind the plate. Hold the phone landscape. Line the batter's feet up with the on-screen guide, keep the light behind you, and let the 3-2-1 countdown start the clip. Clips up to 10 seconds. That's the whole thing. Film one swing and see what your players are working with.
