EasyServe

Prop your phone on the net, serve, and see your speed the moment the ball lands. No radar gun, no sensors, no subscription.

EasyServe turns your phone into a serve radar. Prop it on the net band, walk back, and serve. It hears the racket and the bounce, times the flight, and tells you how fast you hit it.

No extra hardware. No sensors on your racket. No subscription.

HOW IT WORKS

Your serve makes two sounds: the strike and the bounce. EasyServe measures the gap between them and works backwards through the ball's flight, accounting for air drag, to get your speed. All of it happens on your phone.

SEE IT WHILE YOU PLAY

Turn the phone around and the screen faces the court, so your speed flashes up in numbers big enough to read from the baseline. No walking back to check.

EVERY SERVE, WITH THE CLIP

After a session you get every serve, its speed in km/h and mph, and a video clip of each one with the speed burned in. Save the good ones to Photos. Sort by speed to find your best, or by time to see how a session went.

HONEST NUMBERS

Every reading comes with a margin, because a speed without one is a guess dressed up as a fact. Serves the app is confident about are separated from ones it is not, so noise never gets counted as a rocket.

WANT IT EXACT?

Tap any serve and mark where you stood, where the ball landed, and where the phone was. With the real geometry instead of an average, the margin tightens considerably.

IT LEARNS YOUR COURT

Tell it when it got one wrong and it trains a detector tuned to your court, your racket and your phone. Training happens on the device, in a second, with one button.

PRIVATE BY DEFAULT

Your video, your audio and your speeds never leave your phone. There is no account and no login. Sharing anonymous measurements to improve the app for everyone is optional and switched off unless you turn it on.

WHAT YOU NEED

A phone, a net to prop it on, and somewhere to serve. Quieter courts read better, and wind is the main thing that gets in the way.
