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. HOW TO USE 1. Open arithmetic.zetamac.com 2. Play a game — ZetaCoach tracks every problem automatically 3.
