StrikeMetric is two wrist-worn sensors and a mobile app that measures your boxing performance in real time - and builds a complete record of it across every session you train. All data private.
You wear one sensor on each wrist. Every punch you throw is captured: which hand, what type, how hard, how fast. The app processes this instantly, with no internet connection required. When the session ends, the full breakdown is ready. The next session, it compares. Over time, it builds a performance baseline that is entirely your own.
No leaderboards. No comparisons to other athletes. The only benchmark is you - session by session.
WHAT IT MEASURES
⚡︎Output: Total punches, punches per minute (PPM), offensive tempo, punch speed inside combinations, combination count.
⚡︎Power and speed: Peak power per punch (measured in G-force), average power, punch speed (km/h or mph), power punch ratio - the share of your strikes that cross your personal power threshold.
⚡︎Fatigue: How your output, power, and speed change from the start of a session to the end. Round one versus round four. Quantified, not guessed.
⚡︎Technique: Automatic punch recognition - jab, cross, lead hook, rear hook, lead uppercut, rear uppercut. Per hand. Classified in real time using on-device machine learning. No cloud required.
⚡︎Balance: Left versus right hand distribution across the session. How that balance shifts as fatigue builds.
⚡︎Progress - CPI and LPI: LPI (Live Performance Index) runs during every session - a real-time score showing how your current output compares to your personal baseline. Power, pace, and consistency combined into one live signal.
CPI (Composite Progress Index) is your long-term score. It unlocks after your 10th session and measures overall session quality - not just volume, but how hard, how fast, and how consistently you performed. A score above 100 means this session was above your personal reference. This is your most reliable signal of real improvement over time.
WHY THE HARDWARE MATTERS
Most boxing wearables use sensors rated to 16-32G. A light punch starts at around 12G. A power punch on a heavy bag easily exceeds 50G - a sharp hook or cross goes well beyond that.
When a sensor hits its ceiling, it stops reading accurately. The data beyond that point is clipped or estimated.
Think of a speedometer that cuts out at 30 km/h and then starts guessing: 45, maybe 60, maybe 99. The number on screen looks real. The reading underneath is not.
StrikeMetric sensors are rated to 320G - capturing the full acceleration curve of every punch, from controlled shadowboxing to maximum-effort bag work. No clipping. No invented data.
Battery life: 9 days in Stand-by mode, 22h active training.
THE APP
The app runs entirely offline on your phone. No subscription. No cloud dependency. No recurring fee. All data stays on your phone.
⚡︎During training: Live dashboard with real-time metrics - power, speed, PPM, hand balance, LPI score, fatigue signal, punch radar chart, punch heatmap.
⚡︎After training: Full session breakdown - power curve, fatigue map, punch type distribution, hand balance, combination analysis, CPI score.
⚡︎Across sessions: Progress tracking, personal baseline, long-term trend history. Every session stored and fully comparable.
⚡︎AI Coach: After each session, the app generates a structured data summary populated with your real numbers. You paste it into any AI assistant and receive specific coaching feedback based on what actually happened - not generic advice. For one session or compare various sessions.
⚡︎Training log: Every session is automatically saved in full detail. The record your training diary was always trying to be - without the effort, without the memory gaps, and without the guesswork. Save and print .txt file in case you like paperwork.
⚡︎Share across 3 devices: One pair of sensors can be paired with up to three phones - yours, your training partner's, a sibling's. Each device keeps its own profile, history, and personal baseline. Swap whenever. No accounts, no cloud, no setup hassle.
WHAT IS IN THE BOX
