Zetacoach

Live analytics, weak-point detection, and personalised practice plans for
arithmetic.zetamac.com. Track every drill. Climb tiers.

ZetaCoach turns arithmetic.zetamac.com into a real training tool.

Every problem you solve gets timed — comprehension speed, execution speed, and total
latency — then sliced by operation, operand, and fact family. The result: you stop
guessing what's slow and start seeing exactly which numbers cost you points.

WHAT YOU GET

⚡ Live side panel — Comprehension and execution times update as you type, with
speed-zone classification (Direct Retrieval → Procedural → Systemic Friction). Drag it
anywhere on screen.

📊 Full dashboard — Fact-family heatmap, trend chart, per-tag sparklines, session
drill-down, and prescriptions that target your weakest patterns.

🎯 Coach tab — Auto-detects your weakest fact family (e.g. "× 12 table") and
pre-configures a ZetaMac session to drill exactly that. One click to launch.

🏅 12-tier ranking system — Unranked → Iron → Bronze → Stone → Silver → Gold →
Platinum → Diamond → Master → Grandmaster → Elite → Legend, based on your all-time
best score. Each tier shows your estimated population percentile. Tier-up animation
when you break through.

🎮 In-dashboard drills — Adaptive, Metronome, Stamina, and Free modes for focused
practice between ZetaMac sessions.

🔒 100% local — All data stored in your browser. No accounts, no servers, no tracking,
no telemetry.
