How it works
Three things happen: you set the phone down, you throw, and the pen is waiting for you afterwards.
Set it downand throw
Stand the tripod about two feet behind the pitcher, frame the lane, and go. There is nothing to strap on, nothing to calibrate between guys, and nothing in the ball. Peppr reads from 40 feet out to a regulation 60 feet 6 inches, so the same setup covers a 10U pen and a varsity pen.

Know your numberwith confidence
The velocity is called out loud the second the ball lands, and it is a number you can stand behind. We run Peppr next to a Pocket Radar on the same pitches in the same cage — that is what you are watching here — and every result, hits and misses, goes in the accuracy section below. The screen carries the rest as it happens: ride and run, spin rate, how much of that spin is doing work, and the axis it came off at.

Go back throughthe whole pen
Every session saves itself. Open it and the totals are already there — pitch count, average and top velocity, strike percentage, and how tight the release point stayed. The command chart plots where all of them actually finished, and any single pitch plays back on its own.

What pitchers say
“I stopped guessing. He throws, the number comes back, and we both know whether the last change actually did anything.”
Know your numberwith confidence
Every pitch thrown once and measured twice — by Peppr and by a Pocket Radar, side by side, same pitch. We publish the misses too. The side-by-side test is being run now; the figures below are placeholder.

Hardware prices are each manufacturer’s own published price, except HitTrax, which does not publish pricing — that figure is the commonly reported entry price for a system. Subscriptions are each company’s published price, shown per year: Full Swing KIT Player membership is $99.99 a year, Rapsodo’s Individual Pro Series membership is $500 a year (High School $1,000, Team $1,500) and is required to run the device, Pocket Radar’s $49.99 a year is its Plus subscription, which adds tagging and charting (the base app is free), and HitTrax does not publish the subscription for its Pro system — the ~$1,500 a year shown is the commonly reported facility rate (its Home system is $49.99 a month, $599.88 a year). Data points come from each product’s own published metric list: Pocket Radar publishes velocity only, Full Swing KIT publishes “Pitch Velo, Pitch Spin Rate,” and HitTrax Pro publishes velocity, location, late break and pitch angle.

Questions
How accurate is it?
We are running a side-by-side test right now — the same pitch, thrown once, measured by Peppr and by a Pocket Radar at the same time. Every result goes in the accuracy section above, including the ones we miss. Until that test is finished the figures on this page are marked as placeholder, and we would rather say so than publish a number we cannot stand behind.
Why is the number different from my radar gun?
Peppr measures velocity out of the hand. A radar gun standing behind the catcher measures it closer to the plate, after the ball has already lost speed — usually about three miles an hour on the same pitch. Neither reading is wrong. They are measuring two different points in the flight, and pro pitching data is quoted out of the hand.
What do I need to use it?
An iPhone 12 or newer running iOS 17 or later, and a tripod that gets the phone about five feet off the ground. Nothing goes in the ball and nothing straps to the pitcher.
Where does the phone go?
On the tripod, roughly two feet behind the pitcher, framing the lane. The app shows a framing guide and tells you when you are lined up. It takes about a minute the first time and a few seconds after that.
How far away can the pitcher be from the plate?
Anywhere from 40 feet out to a regulation 60 feet 6 inches, so the same setup covers a 10U bullpen and a varsity pen without changing anything.
Does it work indoors?
Yes. The session in the screenshots on this page was thrown in an indoor cage, through netting, under shop lighting. Peppr checks the framing and the light before the first pitch and tells you if something is off rather than guessing.
What do I actually see after each pitch?
The velocity is called out loud the moment the ball lands, so nobody has to walk back to the phone between throws. On the screen you get the ride and run, spin rate, how much of that spin is doing work, the axis it came off at, and whether it finished a ball or a strike.
What happens when the seven days are up?
It becomes $10 a month, or $120 billed annually. You can cancel any time, and cancelling stops the next charge rather than cutting off the sessions you have already recorded.
How is this different from a radar gun?
A radar gun gives you one number. Peppr gives you the number plus everything that produced it — spin, axis, break, and where the pitch finished — and it keeps a record of every session so you can tell whether a mechanical change actually did anything. A Smart Coach is $399 and measures velocity only.
