Fix your toss.
Fix your serve.

Set your phone on a tripod and serve. TossBuddy watches your toss. Every single one. The call is up before the ball reaches the top, so a bad toss never becomes a bad serve.

One email when it opens. Nothing else.

Your toss is the one part of your serve you never see.

What is the most important shot in tennis?
The serve.
What is the most important part of the serve?
The toss.
So how well do you know yours?
That is the problem.

Your last 10 tosses

5 of 10 found the zone.

Each ball replays from your hand, over your head and down into the zone. One never got high enough to count.

Everybody analyses the serve. The grip, the trophy, the leg drive, the pronation. Almost nobody analyses the one thing the whole motion is built around.

Two serves, two jobs

Pick which serve, and start.

A first serve and a kick serve want the ball in different places, so they are called differently. Choose the mode and the target moves with it.

First serve

Big serve, easy points.

Out in front and up. A toss in the right place is what lets you hit up and through it instead of reaching, and free points come from the serve nobody gets a racket on.

Kick serve

You are only as good as your second serve.

Everything you can do on a first serve counts for nothing if the second one has to be safe. A repeatable kick toss is the difference between attacking and hoping.

What makes it different

The only app that calls your toss in real time.

And it is there for every session, not just the ones you can book someone for.

Every toss, not a summary

A call on all of them, as they happen.

Not a score at the end of the session, and not something to read at home afterwards. A call on each toss, right now, while you are still on the court. Four calls, and no jargon to learn.

Why this exists

You can feel a bad serve. You cannot see the toss that caused it.

The toss happens above and in front of you, in under a second, while your eyes are following the ball and not your own hand. It is the most repeatable part of the serve and the hardest part to self correct, which is why coaches spend so much of a lesson on it.

Every coach tells you the same thing. Toss it out in front. Almost nobody manages it, and the reason is simpler than technique.

You cannot see where your own toss actually goes. Not roughly, not really. So you are being asked to correct something you have never actually observed, on feel alone, and feel is exactly what goes first under pressure. TossBuddy tells you where the ball actually went. Every single one.

1

A mirror does not help

You cannot watch yourself and toss at the same time. By the time you look, the ball has already gone where it was going.

2

Video is a homework problem

Filming yourself means reviewing it later, at home, long after the feel has gone. The correction has to happen right now, on the toss you are hitting.

3

Court time is on the clock

Most people are paying by the hour. Any minute spent fiddling with an app is a minute not spent serving.

The alternative

Practising alone is boring, and it does not tell you anything.

You hit fifty serves by yourself. Some of them felt better than others. You go home with no real idea which ones were actually good, so you have practised the repetition without practising the thing you came to fix.

Someone standing next to you would tell you. That is also the expensive way to find out, and almost nobody can have a coach there for every single session.

So why not do it with a buddy?

Someone who turns up every session, watches every toss, and is pleased for you when you get it right.

How it works

Two things, then you serve.

Setup is one line on the screen and one glance. It is built to be done with a racket already in your hand.

1

Put it on a tripod

A tripod or a cart mount, portrait. It has to be off the ground and it has to be still. Handheld does not work.

2

Line it up

A yellow line sits across the screen. Get it running the same way as the baseline. Parallel is what matters, and sitting right on top of it is a bonus, not the job.

Serve

Each toss gets its own call on the screen while you are still standing there, not later at home.

Practice anywhere

No court? No problem.

The toss is the one part of the serve that needs no net, no opponent and nothing booked. A wall, a driveway, a patch of grass in the park.

Set the tripod up, keep your feet under the yellow line, stay directly behind it, and every toss gets called exactly the way it would on court.

Indoors it switches over by itself. There is nothing for you to press and no setting to find, so a garage at dusk works the same as a court at noon.

The only thing you cannot improvise is the tripod. Ten minutes in a driveway is ten minutes of tosses. The serve needs a court. The toss never did.

After the session

Hitting your goal does not end anything.

Set a goal of nine tosses, or eighteen, or thirty six. Reach it and the bar keeps going, because a goal is a milestone and not a finish line. Go past it and it tells you by how much.

Who the buddy actually is

He is not a mascot. He is the person who built the app.

The buddy standing on the court with you is Sky Kim, founder of Road to Pro. He wrote TossBuddy because he had spent years teaching the same lesson in person and watching it fade the moment the lesson ended.

That lesson was not taught a handful of times. He has sent players on to Division I programmes and Ivy League teams, coached on the WTA tour, and coached a player into the ATP world top twenty. The toss came up in almost every one of them, which is the whole reason this app exists.

Let's fix that toss.

Leave an email and we will tell you the day it opens. That is the only reason we will use it.
