Squash Coach App is a courtside rally tracker. During a match you record each rally with two taps — outcome then court position — and optionally draw the ball's trajectory. The app infers the shot type and direction from your drawing and builds a live heatmap and coaching summary ready for the changeover. After multiple matches it generates AI-powered longitudinal analysis of a player's development.

Draw the ball's path after placing a dot and the app determines:

Boasts and corkscrews have no St/C prefix — their direction is determined by the shot geometry itself. St/C applies only to drives, drops, volleys, lobs and kills.

Every rally is stored as a compact code: outcome + [direction] + shot + [modifiers] + rally number.

Hover over any dot on the court to see the full code and description.

The heatmap shows density at each position where a shot was played from. Use the filter buttons to isolate what you need:

• W (green) — where the player is winning rallies. Front-court clusters show effective attacking positions.
• L + l (red) — where the player is losing rallies. Back-corner clusters show where the opponent is winning the length battle.
• W only — outright winner positions. Reveals which areas of the court the player can attack from with confidence.
• L only — own error positions. Identifies where decision-making is breaking down.

Open the menu and choose ⊞ Match & Game Analysis. It opens on the Full Match tab, with a tab for each completed game alongside it — heatmaps, stats, rally log and a written summary for whichever you pick.

• Factual summary — score narrative, best shot by win rate, error breakdown by shot type, stroke count, opponent pressure. Available on all plans.
• ✦ AI Tactical Insights — three priority-ranked coaching observations. Cached; the button reads ↻ Update AI Tactical Insights once new rallies have been added. Standard and above on the Full Match tab; Pro and Club on the per-game tabs.
• ↩ Load Game n — put a completed game back on the live court to add or correct annotations.

You do not have to come here at a changeover — the Changeover Card opens on its own the moment a game is won, and Start Game n on it takes you straight into the next game.

Point-a-rally scoring to 11, win by 2 clear, best of 5 by default (configurable in Match Settings). When a game ends a banner appears — tap Start Game n to continue. Completed games are saved automatically within the match session.

Missed a point? Tap the score number on the scoreboard to record a point without placing a dot. The code will show as w?? or l?? in the rally log. Use ↩ Undo to reverse it if needed.

Tap ↓ Save Match in the menu to save the completed match. Saved matches appear under Saved Matches in the menu, grouped by player.

• Free — up to 10 matches stored locally on this device. Use Export to back up.

↻ Historical Analysis (Standard and above) — every player-opponent group carries a ↻ Historical Analysis button. On Free it shows a 🔒; Standard and above open it. It generates an AI longitudinal report covering tactical trends, development over time, and coaching priorities — integrating all match data and your coach notes.

The core workflow: pick an outcome, tap the court, draw the path. The app infers the shot type from the trajectory, so you focus on watching the match — not memorising codes.

• Shots inferred from path — Drive, Drop, Boast, Trickle Boast and Corkscrew are detected automatically from the geometry you draw.
• Tags for what geometry can't see — V Volley, L Lob, K Kill, H Hold, N Nick, T Tin, O Out, S Stroke.
• Direction auto-inferred — Straight or Cross-court is computed from how far the ball crosses, applied automatically to directional shots only.

Build a roster of players from Match Settings. Each player gets their own colour that follows them through pins, rally logs, and stats.

• Roster by tier — Free and Standard: 1 player. Pro: up to 10. Club: unlimited and shared across coaches.
• Tap-to-switch — ▾ Switch moves between players in one tap; the app warns before switching if you have unsaved match data.
• Nine colour presets — Court Teal, Royal Blue, Forest Green, Plum Purple, Burnt Orange, Slate, Ruby, Amber, Pink.

• Match Date & Time — log when a match was actually played. Date defaults to today each time you open Match Settings.
• Event Name — free-text tag such as County League or Club Championship. The app remembers your five most recent event names as quick suggestions.
• Coach Notes — free-text observations at match end. Stay editable and feed into AI analysis.

Visual analysis from the first rally onwards, with filters that isolate the pattern you're looking for.

• Live heatmap — pins appear on the court where each rally was struck, coloured by outcome.
• Outcome filters — W · L · w · l. Available on both the in-game heatmap and the Historical Analysis aggregate view.
• Paths toggle — overlay the drawn shot trajectories as polylines on the heatmap.
• Coaching Summary — two mini heatmaps (Won / Lost), four stat tiles, and a changeover flashcard with a one-line AI directive ready to read to the player.

Three priority-ranked coaching observations powered by Claude, labelled Priority, Tactical, and Observation.

• Standard — AI insights after every match.
• Pro — AI insights after every game as well as every match.
• Cached, not stale — insights are cached per game. The ↻ Update button only appears when new rallies have been recorded since the last analysis.

Head-to-head reports (Standard & Pro) turn a player's full match history against one opponent into a single longitudinal view.

• Performance trend chart — each match shown as a W/L bar with score, plus a point-win % line and a dashed 50% reference.
• Aggregate heatmaps — pool pins across every match in the pairing, with the same outcome filters as the in-game view.
• Per-match timeline — date, event tag, score, with drill-through to any match's individual Coaching Summary.
• AI Longitudinal Report (Pro) — Claude synthesises every match and all coach notes into four sections: Performance Trend, Key Strengths, Key Weaknesses, Training Recommendations.

• Saved Matches — matches between the same two players are grouped together. Tap ◈ Historical Analysis on any group for the full head-to-head.
• Cloud sync (Standard & Pro) — matches save automatically to the cloud and are accessible from any device you sign in on. Free matches stay local.
• Import & Export — export any match as a file including every pin, score, trajectory, and coach note. Import restores it exactly on any device.

Every analysis view can be saved as a PDF to hand to a player or keep on file.

• Match summary (Standard and above) — ▼ Save to PDF on the Full Match tab of ⊞ Match & Game Analysis.
• Per-game report (Pro and Club) — the same button on any individual game tab.
• Historical report (Pro and Club) — ▼ Save Historical Report to PDF inside Historical Analysis.

A locked button shows which plan unlocks it rather than disappearing. PDF export is the one feature that needs a connection the first time it runs — everything else works offline.

The app speaks in red and green by default — green for rallies won, red for lost. For roughly one man in twelve that is unreliable, and it is the app's whole visual language.

Menu → Colour-blind mode switches every dot, outcome button, filter and heatmap to the Okabe–Ito blue/orange palette. Nothing is lost and nothing has to be guessed at. Available on every plan.

Light and dark follow your device, and can be switched from the menu.

• Enter — finish the trajectory you are drawing (same as a double-tap).
• Escape — cancel the trajectory, close the menu, or back out of renaming a player.

Hover any dot on the court to see its full code and a plain-English description of the rally.

Square brackets denote optional parts. Direction (St/C) is auto-inferred. H/N/T/O are tags you add.

Draw the ball's path after placing the dot — the app reads the geometry and fills in the shot automatically.

Trajectory can't see timing, arc, or aggressive intent. Tap a tag before or after drawing.

Auto-inferred from how far the ball crosses the court. Only added to directional shots (Dr, Dp, V, L, K). Boasts, corkscrews, reverse angles, and strokes carry no direction prefix — their geometry defines it.
