ZeroMark turns your iPhone camera into a precision range analyst. Photograph any IDPA target after your shooting session and Machine Learning Vision scores every shot in seconds — zero zone, minus-one, minus-three, head box, or miss — with a confidence rating for each impact. INSTANT AI SCORING Point your camera at your paper target, capture the image, and ZeroMark's vision analysis pipeline maps every bullet hole to the correct IDPA zone. No manual counting, no spreadsheets, no guesswork. Raw accuracy data, right at the range. SHOT-LEVEL DETAIL Tap any shot on the interactive canvas to inspect its zone, confidence score, and exact normalized position on the target. PERFORMANCE ANALYTICS Track your progress across sessions with a full analytics dashboard: · Accuracy trend charts over time · Zone distribution breakdown (A-zone %, C-zone %, misses) · Clock-position diagram — see your consistent pull direction at a glance · Centroid bias compass — where your group center actually lands · Shot grouping trend — tighten your groups over weeks · Performance radar — multi-axis snapshot of your current skill profile AI COACHING CARDS ZeroMark detects fault patterns — low left pulls, high fliers, inconsistent grip pressure — and surfaces targeted coaching cards with drills designed to fix the specific mechanical fault it identified. YOUR ARSENAL Log every firearm in your safe: make, model, variant, caliber, notes. Add your ammunition loads. Track which gun you used in each session and compare average points across your entire collection. DRILL LIBRARY Built-in drills for accuracy, speed, draw, and movement — organized by category. Add custom drills for your own training protocols. SESSION COMPARISON Select any two sessions and compare them side-by-side: zone breakdown, total score, round count, and grouping — so you can see exactly what changed and what didn't. BUILT FOR SERIOUS SHOOTERS ZeroMark is designed for IDPA competitors, practical shooters, and anyone who wants to improve accuracy with data instead of gut feel. The app stores everything locally using SwiftData — your training history stays on your device, or in iCloud. Privacy: all analysis is processed via iOS Machine Learning Vision. No account required.
