Where it goes
Waistband clip, approved body placement, or future racquet/gear mount.
Stroke and serve
What HyperPulse measures for Tennis & Racquet
Stroke count, serve-effort proxy, footwork bursts, and court-session context.
NO GPS motion-first sensor
SPINE CLIP or approved placement
APP parent-readable reports
DEVICE + APP | SAMPLE RENDER
Why it matters
Racquet coaches get stroke volume, burst windows, serve effort, and session load context.
What it is not
Training-grade movement context only. HyperPulse does not make medical, injury, concussion, safety, return-to-play, college-placement, funding, eligibility, or official-record claims.

Motion intensity
See the session shape, not just the final number.
HyperPulse turns motion windows into parent-readable context: start, burst, effort, fade, load, and notes. These charts are sample visuals until real app screenshots replace them.

Questions parents and coaches ask.
Direct answers make the site easier for people and easier for AI/search engines to understand without misquoting us.
Does HyperPulse replace a tennis coach or video tool?
No. It adds motion context that can sit next to coaching and video review.
Can it measure official serve speed?
No. Serve speed is a proxy unless paired with a validated ball-tracking system.
