Volley Velocity: Spike Tracker

Volley Velocity measures volleyball spike speed from any phone video. Film a spike, trim to the contact, and get your spike speed, contact height, approach angle and a Power Score in seconds — no radar gun, no coach standing courtside.

HOW IT WORKS
1. Record or upload a clip of your spike, up to 30 seconds.
2. Trim to the contact, frame by frame.
3. The analyser reads the hit and shows your numbers.

WHAT YOU GET ON EVERY SPIKE
• Spike speed — ball speed in mph or km/h
• Contact height — how high above the net you made contact
• Approach angle — how steeply you came in
• Power Score — computed from spike speed and contact height
• The analyser's own confidence in the reading, and how many frames it sampled

A SPIKE TRACKER, NOT A GUESS
Every number comes from your own clip. Nothing on the result screen is a placeholder: the confidence figure is what the analyser reported and the frame count is what it actually sampled. When a reading cannot be trusted, the app says so instead of showing you a number anyway.

TRACK YOUR VOLLEYBALL STATS
A volleyball tracker and volleyball stat tracker in one: every spike is saved, so your peak spike speed, average power and personal best are one tap away. The stats screen charts your spike speed over 7, 30 or 90 days, breaks your hits down by type, and a form radar compares your speed, power, contact height and approach with benchmarks for your position and age. Over a season it is the clearest way to see whether your volleyball training is making you hit harder — measured, not felt.

SPIKE SPEED LEADERBOARD
Opt in and your best spike ranks on the leaderboard — against friends, your team or every player, this week, this month or all-time, filtered by age group and by city, state or country. Tap a ranked player to watch their best spike or open their profile: peak spike speed, power and recent hits. You stay hidden until you switch it on, and readings the analyser flags as suspect never rank.

WHAT THE NUMBERS MEAN
Spike speed is ball speed off the hand — the figure a radar gun would give you courtside, from a clip you already filmed. Contact height is how far above the net you met the ball, often the difference between a spike that gets dug and one that does not. Approach angle is how steeply you came in, and the first thing to check when a spike stops landing.

NO RADAR GUN, NO COURTSIDE SETUP
Volley Velocity needs a phone and a clip. Film from the stands, from the sideline, or hand the phone to a teammate between reps. Nothing to mount, nothing to calibrate, nothing extra to carry to practice.

FOR COACHES AND PARENTS
This is a measurement tool, not a training program — it does not hand out drills or workout plans. It tells you whether the volleyball training you already do is working. Follow a hitter through preseason, log every practice spike, and compare the season curve instead of a feeling. A team code puts a whole squad's peak spike speeds on one roster.

COMPETE WITH YOUR TEAM
Create a team with one code and invite friends in seconds. Club practice, a high school squad or a college tryout — Volley Velocity settles who spikes hardest.

BUILT FOR HITTERS
Made for outside hitters, middles and opposites chasing a faster, higher, harder spike. Spike speed, contact height and approach angle are the numbers coaches actually care about.

Volleyball spike speed, spike tracker, volleyball stats — measured from your own video.

Recent changes:
More readings, fewer retakes. When the first look at your clip can't measure the spike, the analyzer now looks again before asking you to refilm. Uploads retry on a weak connection, and a slow analysis no longer spins forever. New: quick filming tips before your first clip. Pro adds a weekly plan next to yearly and monthly.
