Read full descriptionHide full description
Kumite Punch Tracker uses Apple Watch wrist motion to count straight punches and estimate wrist speed, with session history and training analytics on iPhone. ON APPLE WATCH - Start a workout and track straight punches from a briefly settled guard - See live punch count, pace, estimated wrist speed when available, and optional heart-rate context - Choose Automatic, Standard, or Enhanced motion sampling; supported watches can use 200 Hz batches to refine speed during workouts - Pause, resume, and end sessions, with configurable inactivity timers ON IPHONE - Review punch totals, available speed estimates, session history, and trends - Explore daily, weekly, monthly, yearly, and all-time stats - Inspect punch-by-punch speed, heart-rate context, and observations of the watched hand's return movement - Use fighter profiles and left/right hand filtering - Adjust detection settings and sync them to your Watch - Export CSV files with measurement and settings details - Dark mode support YOUR DATA STAYS YOURS No app account is required. Sessions are stored on your devices and sync directly between your own iPhone and Apple Watch. No ads, third-party analytics, or tracking. MEASUREMENT NOTE Speed is an experimental estimate of wrist movement, not exact fist speed. Physical accuracy and repeatability across Watch models have not yet been established. Movement, watch fit, sensor sampling, and the starting position can affect detection and estimates. Speed is shown as unavailable when quality checks fail. Return-movement observations describe the watched hand and do not grade hikite technique or verify hand and elbow placement. REQUIREMENTS Punch capture requires a physical Apple Watch running watchOS 10 or later, paired with an iPhone running iOS 17 or later. Higher-rate capture is checked at runtime and falls back when unavailable. SUBSCRIPTION Kumite Punch Tracker Pro is $2.99/month, with a 3-day free trial for eligible new subscribers. Localized pricing and offer eligibility are shown before purchase. Payment is charged to your Apple Account; the subscription renews automatically unless cancelled at least 24 hours before the end of the current period. Manage or cancel in Settings > Apple Account > Subscriptions. iPhone features require an active subscription.

Verdict
The clearest difference is in-app purchases: Nitro Swim at none against Kumite Punch Tracker's 1. Nitro Swim also leads on iOS requirement (15.1 vs 17.0). On price, update cadence, ads and device support there is nothing between them.
